Multi Round Robin Tournament Management

Frequently Asked Questions

What is multiroundrobin.com?
Multiroundrobin.com is a platform that empowers clubs and associations to oversee internal member ratings and organize multiple round-robin tournaments. In these tournaments, members and guests compete against those with similar ratings. Multiroundrobin.com offers flexibility in terms of tournament management, allowing organizers to:
  1. Take full control of tournament management.
  2. Delegate all the tasks to the players.
  3. Utilize a combination of both approaches for tournament administration.
Is this site free?
Yes. The site uses banners to finance itself. As long as our visitors are interested to our sponsors and visit them, we can keep this site free.
Which rating systems can be used?
At this time the club can choose among the following rating systems:
  • Based on the USATT rating system
  • based on the ITTF World Ranking System(under construction http://www.ittf.com/_front_page/ittf_full_story1.asp?ID=22863&Category=
  • Old USTTA Rating System
  • Elo rating system (under construction)
  • Based on the USTA rating algorithm (under construction)
In addition a club can add some custom parameters like:
  • A minimum rating value
  • Additional points to be added for players who win all matches in their group. (This value can also be reduced for each game lost)
How does multiroundrobin.com calculate each groups ranking?
The ranking inside each group is calculated using the following criteria. Each criterion is used only when the prior criteria return a match.
Individuals [1] and teams ranking:
  1. The player with the highest difference among won matches and lost matches
  2. The player with the highest difference among won games and lost games
Best Couple (For Couples/Doubles tournaments where Couples are chosen by multiroundrobin.com and players rotate during the tournament)
  1. The couple with the highest ratio among won matches and lost matches
  2. The couple with the highest ratio among won games and lost games
[1] Individual Ranking is used for singles tournament, teams tournament, and Couples/Doubles tournaments, where couples are dynamically chosen by multiroundrobin.com and players rotate during the tournament. Since the couples changes during a Couple/Double Tournaments, the classification is made per each single player, however the best couples are also provided using the criteria shown above.
Can multiroundrobin.com manage double/couple tournaments?
Multiroundrobin.com can organize multi group round robin tournaments in which the composition of the teams is set by the software and it changes dynamically during the tournament. Groups can be set from 5 to 14 players per group and every player will play 4 matches. Multiroundrobin.com double tournaments are not pure round robins in which every team is set before the starting of the tournament, and they play against all the other teams.
How do I find a partner for a double/couple tournament?
Multiroundrobin.com will team up players; therefore, you just register like a single tournament. In most cases teams are not static, but they change during the tournament. For every match, players have different opponent and often different partner. This logic allows to have groups of any number of players, and, even with odd number of players, all the players will always play 4 matches. (An exception to the "4 matches feature" is when one or more players don't play all the games.)
Multiroundrobin.com flexibility will even allow tournament administrators to set multiroundrobin.com to choose whether partners should be kept together as much as possible, or they should change as much as possible. In both cases multiroundrobin.com will never partner together the 2 players with the highest rating or the 2 with the lowest rating, and teams are created so that the total rating of one team is always as close as possible to that of the opponent team.
Playing double, what happen when one player don’t show up or leave before playing all games?
When one or more players are missing at the starting of the tournament, or as soon as it is known that one player is no longer playing, one of the player in the group (or a tournament manager) has to click on the "report absent" link for that player in the “enter results" page, and multiroundrobin.com rearrange all the matches trying to assure that every player keep playing at least 4 matches. Some players might need to play 5 matches to overcome the missing player(s). This can be applied again as long as there are at least 4 players in the group. Before clicking the “report absent” link, make sure that all played matches have a result, and temporarily change the result for matches in progress to 0 to 0 (or any other result different from "-") so that multiroundrobin.com saves those matches. All matches with a result with both dashes will be replaced by a new match with available players.
In doubles, for each group, how many matches are played and can matches be played in parallel?
The following table show characteristics for each group based on the number of players in the group:
Matches per player44444444444
Total matches4567891011121314
Roundsn/a n/a n/a n/a 4556677
Parallel matches111122222 or 32 or 32 or 3
[1] 4 players group is only available when a 5 players group looses one player. For this group composition there are teams in which both players have a higher/lower rating than their opponents, and rating optimization is not possible. Also, to ensure 4 matches per player, one of the match is played twice.
Does playing double affects my club rating?
Multiroundrobin.com keeps 2 separated rating for single and double. Double rating is also associated with the individual and not to the team. When you play double, your rating increase or decrease is calculated together with your partner, but then, it is separately applied to you and your partner.
When you enroll to a club you only provide your single rating. The first time you play double the system use your single rating to rate you for the double. From this time on, multiroundrobin.com keeps your 2 ratings separated.
How Do I Use Multiroundrobin.com?
  1. Registration:

    If not registered, click "login/register" and choose "Register" at the form's bottom.

  2. Tournament Entry:
    • Log in, open the top-right hamburger menu, and select "Tournament Registration". You'll see a list of all tournaments you can play.
    • For first-time tournament play at a club, seek manager confirmation for your rating and status.
    • From the second time onward, if allowed by your club, check the tournament's checkbox to register. Once checked you are registered. Unselect to unregister.
  3. Manage Your Tournaments:
    • Access "my active tournaments" from the hamburger menu.
    • Make sure you are registered.
    • Once the tournament begins, this page will automatically change and show you your round robin group and matches. Click on any match to enter the match result.
    • If your club uses Multiroundrobin.com for table assignments, your designated table will be displayed at the top of the page.
How do I enroll to a club/association in order to play tournaments?
  1. Verify that your club uses multiroundrobin.com
  2. If you are not registered to multiroundrobin.com, register to multiroundrobin.com by selecting "Login/Register" and then "Register"
  3. If you are already registered to multiroundrobin.com, login to it, then open the hamburger menu on the top right and select "My profile". Click the editing button and then the "Add club" button at the bottom and follow the on-screen directions. You can add as many clubs as you wish but only one per each submit.
Why am I unable to find the tournament I’d like to register?
First, ensure that you have selected the club where you'd like to play the tournament. You can check it, and, if needed, add the club by going to "My Profile." Then, verify that your age, sex, and rating meet the tournament's restrictions.
My opponent didn’t want to play or didn’t show up, what should I do?
The club can set the system to subtract penalty points from the rating of players whose score is equal to "-". In case the club has enabled this feature (check here), it should have provided rules on how to manage these scenarios. In case it hasn’t, the general rule is to change the score of the available player from "-" to "0", and to leave the score of the not available player to "-".
When one of the scores is equal to "-" and one to "0", the player with "-" loses the points as set by the club, and loses the match. The player with the "0" wins the match, but he/she doesn’t get any change in his/her rating.
I don’t have an Internet device, how do I enroll to a tournament and enter my results?
Any assistant in your club can enroll and enter your results. Results can also be entered by any player in your group.
How do I define a new club/association?
First you have to be registered as user to multiroundrobin.com. Then go to "Management -> Manage Clubs" and add the new club. You’ll be one of the administrators for the club, so you will be allowed to create and manage tournaments for the club.
How are members/guests added to a club/association?
Members or guests have to register first to multiroundrobin.com. Once a user is registered to the site, he/she can enroll to as many clubs as he/she wishes going to "My Profile". When a user enrolls in a club, he/she is enrolled as a guest. Administrators can change the status of the user from guest to member.
Members/guests can also be added by administrators and assistants before a tournament (see next question)
How do I create a new tournament?
To create or manage a tournament you have to be a manager for the club. As manager, you can go to "Management -> Manage Tournaments" and add a new tournament. From that form you have to select a tournament model and then provide the date of the tournament. All the other fields in the form will be automatically filled with data taken from the model, and you can keep or change them.
What is a tournament model?
A tournament model contains all custom parameters that define a tournament. To create a new tournament you only have to choose one of your models and possibly change only a few values or even only the starting date. You can create a new tournament in less than a minute.
Can I Modify a tournament after I have created it?
Some parameters can be changed others not. In general, you can modify the parameters until it is still possible doing it. For example, you can change the tournament start time before the starting time, but not after the tournament has begun.
Can I delete a tournament?
Tournament managers can delete a tournament before registration begins. After registration starts and until results can be updated (which is when new ratings and statistics are created), only the tournament creator can delete it. To delete a tournament, go to "Management," select "Manage Tournament," choose the tournament, and click the delete icon. The software may ask a few questions before confirming the deletion. Registered players will receive a notification email about the tournament cancellation.
Can I add a player after the tournament has started?
Yes, there are two ways to add one or more players up to half an hour after the tournament has started. However, adding players after the tournament has started may negatively affect other players, and should be used sparingly. If you do add players after the tournament has started, you should do so as soon as possible and notify the players in the affected groups that their groups have changed, so they can refresh their page and see their new opponents.

The first way to add a player involves adding one player to a group. If the group to which the player is going to be added is small (e.g.: 4 players), the software will simply add the player to that group. If the group is large (e.g.: 5 players) then the software will try to move one player into an adjacent small group and then add the new player to the group. This is only possible if there are adjacent small groups. To use this method, go to "Management," "Tournament Recovery Tools," and "Add a Player." Keep in mind that one or two groups, player compositions will change, matches already played might no longer be required, and any results already entered in those groups will be lost.

The second way to add a player involves going back to the registration status. To do this, go to "Management," "Tournament Recovery Tools," and "Reopen Registrations." This will destroy all created groups and matches as if the tournament has never started. All already entered results will be deleted. Groups will be created ex novo when the new tournament time is reached. Remember to inform everybody about the restart so players know the tournament will have a new restart.

In both cases, since some matches will change and others will not, you should provide clear rules about started and already finished matches. One possible rule is that for every group that changes composition, every match will be void (when registrations are reopened, all groups have to reenter completed match results).
Is it possible to select who can participate in a tournament?
Yes. You can choose any combination of the following criteria:
  • Members only (vs. members and guests)
  • Sex (men, women or both)
  • Age range
  • Rating range
How are tournament groups created?
Groups are always created so that players play against players with a rating as close as possible to theirs. However, you have many parameters to customize the group composition according to your own preference, like max number of players, max number of groups, optimal number of players per group, including several parameters to choose how to manage uneven groups.
Can I adjust the group composition?
Yes. You can set an interval between the end of registration and the start of the tournament. You can use this time to review the group composition, and manually move players from one group to another.
What are the Member Access Levels and Privileges?
Upon enrolling in a club, users are initially registered as guests. Club administrators and managers have the authority to adjust a user's access level to one of the following:
  • Member: Regular members with standard privileges.
  • Tournament Assistant: Members able to assist players during a tournament.
  • Manager: Able to perform a subset of tasks, particularly related to tournaments.
  • Administrator: Users with full access and control over all aspects.
The following table show in detail the function available for each level.

How do I manage players that don’t show up, or don’t play all the matches, or don’t report results?
Administrators can set in the club management some penalties points that are subtracted from the rating of players whose match score is left equal to “-“. This feature can be used to penalize players who don’t update their result, and to penalize player that don’t play some matches if the club policy is to penalize them. Clubs that decide to use this feature should provide to the players a policy that states how players should enter the results. When setting the policy remember that the system subtract the penalty points to players whose score is equal to “-“; therefore changing the “-“ to “0” will prevent the system from subtracting points. Also consider that the general rule, when a player is not available, is to leave his/her score to “-“ and change the score of the available player to “0”. This rule might be already used by players who also play in other clubs.
What happen if a player forgets to update a result?
You can set a time before the deadline for reporting results at which multiroundrobin.com will send a reminder email to all players who have not yet reported their results. If they still don't enter the results, penalties points could be subtracted from their rating (see previous question)
What happen if a player enters a wrong result?
When a player updates a result, multiroundrobin.com sends an email to the other player, so he/she can check the result, and he/she can correct it if it is wrong. Then, a new email is sent to the first player, and so on. The email might not be sent when the other player has already seen the result.
Can I fix an incorrect result after the statistics have been created?
Yes, you have 4 weeks to fix a match result that has been entered incorrectly. However, since the system will also adjust the players rating, this operation should be done ASAP and ideally before the players play another tournament. If delayed, the correction could negatively impact the players rating. To fix a result go to “Management”, “tournament Recovery tools” and select “Fix Wrong Match Result”.
Why I cannot find a player for registering him/her in a tournament?
Make sure the player is registered to multiroundrobin.com and (s)he has selected your club. Then verify that the age, sex, and rating comply with the tournament restrictions. If you are using the “Register Others” page, check the filters at the top of the page.
Some players are not reliable on reporting results, or they register to tournaments and they don’t show up, can I ban them?
Yes, managers can ban players from either register to tournament and/or reporting results. Managers and assistants can still register them. Other players on the same group, managers and assistants can also report their results.
Can I send an email to all players?
Yes, you can send an email to players who participated in previous tournaments by filtering based on the tournament name and/or time. To send the emails go to “Management”, “tournament Recovery tools” and select “Send Emails to Players”.
What can I do if there is a problem with the software?
MultiRoundRobin.com provides a backup web server that runs a previous version of the software. If you encounter errors using the regular web server, you can try the backup server by visiting www2.multiroundrobin.com (note the "2" after "www"). This option is available for both managers and players. As a manager you should check that www2 works, and then communicate to all players to use www2.multiroundrobin.com instead of the www.multiroundrobin.com. Keep in mind that you will lose access to the latest features added to the software, but the core functionality should work. Do not bookmark this URL, as it is intended as a temporary solution.
What can I do if the previous solution doesn’t work?
As a manager, you can still run a Round-Robin (RR) tournament manually. You'll need access to a printer to produce paper documents for recording results. To use this manual subset of the software, visit www.multiroundrobin.com/local.html from the same devices where you have added players on the previous tournament. This will launch a local web page that allows you to register players that have already played in past editions of the tournament. Then you can create groups that you can print on paper, and also create results sheets, where players can record results. Beyond this point, you will need to complete tournament management tasks manually. Please note that this solution provides basic functionality for players to enjoy a tournament, but there won't be statistics or rating updates for the event.
My club has few tables and many players. How can I manage it?
You can create 2 or more tournaments at different times or days setting the 2 tournaments for different rating ranges. For example, tournament 1 Saturday for player with rating from 0 to 1300 and tournament 2 Sunday for players with rating from 1000 to 5000. When splitting the tournament consider that a RR tournament with groups of 4-5 players lasts about 2 and a half hours. It is advisable to overlap the tournament rating ranges (as shown in the example where tournament 1 last rating is 1300 and tournament 2 starting rating is 1000) to ensure that players with ratings close to the borderline can continue playing in the same tournament, even as their ratings fluctuate.
Can I link to multiroundrobin.com?
Yes. Most of the page can be called directly just copying the complete URL. For example, you can call directly the page with your member rating or with the past result for your club.
Can I include a box with the tournament winners list in my site?
Yes. You can add 3 kinds of boxes that contain the list of the players who won each group. You can have:
  1. Winners of the latest single or double tournament played in the club.
  2. Winners of the latest single or double tournament played in the club that has a specific string in the tournament name.
  3. Winners of a specific tournament.
The format of the box is always the same. To see the box and get the code to put in your page to show the boxes, go to "Statistic -> Past Results", select your club, select one of the tournaments if you have more than one, and follow, at the end of the page, the link to add the winner boxes to your site.

See the winners box instruction page for more information.

Can I change the graphics of the winners list box?
Yes. The graphics of the box can be changed by you just overriding the css tags. You can also delete the call to the css file, and use your own css.

See the winners box instruction page for more information.
