Stack-a-Cash is 3-in-a-row style game played with coins.
The game was made as a challenge to see if a game could be made to fit on one side of a business card.
To play the game you need a 3x3 board and six coins.
You need 2 large, 2 medium, and 2 small coins. Denominations are irrelevant.
One player plays heads, the other plays tails.
All six coins are common to both players.
On your turn you can
place a coin
move and/or flip a coin
Coins can be stacked big to small.
You cannot move or flip a coin that was just moved, flipped, or placed.
Game ends as soon as someone makes three in a row of the same side (heads or tails) on the topmost layer of coins.
Be careful you don't lay traps for yourself, the game is trickier than it looks!
