Think Tank is a minigame in Mario Party 7. In this minigame, one player rides in a big tank, while the other three players ride in smaller tanks. In order to win, the team of one must destroy the three smaller tanks by shooting them until all their health (which is displayed by hearts), and visa-versa for the team of three. Hearts will be taken away for each shot taken. The big tank has ten hearts while the three smaller tanks only have three hearts which provides a big challenge for the team of three.
