How to Play Stack A Cash | place, stack, move, and flip coins to form a three-in-a-row

About Stack-a-Cash, from BoardGameGeek:

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! -description from the designer
