Click on the correct answer to the addition problem to give your tugboat team pulling power. You can choose to create/play in a private game with friends or just play in a public game against the computer and/or other online players. At the end you can view the statistics on how you did against the other player and see any errors you might have made.
To create a private game where you can play with your friends or by yourself against computer players, click the Create Game in the Multiplayer Lobby. Then click the Private Game text in the Create Game box and enter a password. Give the password to your friends and wait for your friends to join the game before starting the game.
