Login & Play
To log into the site, point your browser to, and provide your username and password in the upper right, and press the Login button.
To play a pickup game, press the "Pickup Rounds" link in the menu bar directly below the top banner on the home page. This will take you to the pickup round page. Then click on the big yellow "Play Pickup Round" button. This will open the Online EQUATIONS matchmaker in your browser. If this fails to load, please go back and check your Java version.
Once you are in the Matchmaker Lobby, there are two ways to get into a round with other players. The simplest way is to click on the Auto Round Finder tab at the top of the page. This will bring up the Round Finder button. Clicking on this button will put you into a round when there are two other players who have also clicked on the Auto Round Finder/Round Finder tab and button.
The second method to get into a round is to use the Custom Rounds tab and follow the instructions below. This method depends upon other players who are in the Matchmaker Lobby deciding to manually join the custom round you create. You can chat with them the encourage people to join.
To create a custom round of EQUATIONS, press the "Make Round" button in the main menu of the matchmaker window. This will open a dialog box where you can enter a name for your round, and you then select what type of round you would like to play off the drop down menu (such as Default, 3+ scoring or Timerless round.)
Once you make the Round, you will see your newly created Round in the "Rounds awaiting players" list in the matchmaker. Select your round by clicking on its name in the matchmaker window, and then click the "Join Round" button, which will add your name to the list of Players in that Round and open the Round Lobby window.
At this point, the other players with whom you want to play should themselves select your round, and click the "Join Round" button. Once all the players are listed in the Round Lobby with a red "X" by their name, each player should click on the red X to show they are ready to start. Clicking on the red X will change it to a green checkmark. When all players have green checkmarks indicating that they are ready, one person needs to click the "Start Round" button to begin the first match.
At any point while testing the matchmaker or the EQUATIONS game, please use the "Bug" button to report any problems or concerns.
