The game is free to download and was designed to fit on a standard sized poker card (2.5 inch x 3.5 inch)
Gameplay:
Place the card in between two players and thumb wrestle to see who goes first. The starting player picks two fingers to use for the game and places them on any two (+) spaces. Their opponent uses the same two fingers and places them on any two (-) spaces. The starting player calls out a finger to move to any open space. After their movement, their opponent must respond by moving the same finger to any open space. Players continue to alternate calling out which fingers are to be moved to an open space.
Game End:
A player wins when the opposing player cannot move their finger to an open space or their non-moving finger is lifted or moved from the circle it was currently in.
