How to play: Take part in ruthless thumb battles and try to knock out your opponent in the game Extreme Thumb War. Alone against the AI or facing a friend by playing both on the same device, the objective will be to try to catch or hit your opponent's thumb when it's lowered to inflict damage. To win a round you need to fully empty the life bar of the opposing thumb. If you succeed in trapping your opponent's thumb he will loose more life, but beware of the counter-attack which can be dangerous! Each game is played in three winning rounds. You can choose the look of your thumb from the 20 characters available.
