coin game

A surprisingly amusing and simple game invented by me and gf in Applebees:

1. Place 4 coins in a square about 15 cm wide on a table; this forms the goal.
2. Each player gets an additional 2+ coins set aside in their bank. One player owns all non-goal coins showing heads, the other owns all showing tails. They flip their coins to match this.
3. Winner of previous round starts, attempting to slide/flick a coin from outside the goal into the goal. Once slid, coins are considered to have left the bank and entered play.
4. Whenever a coin in play stops outside the goal, it flips over and goes to the bank of the corresponding player.
5. Continue, alternating turns. If it's a player's turn and they have no coins in their bank they are skipped.
6. Once both banks are empty, whoever owns more coins in the box wins the round.

Penalties:

1. If a player touches any coin in the goal they lose. Hitting something with a coin is not considered touching it.
2. If a player sends a coin into play and it crosses a side of the goal not closest to them before it crosses the side closest to them, they lose the round. "The side closest to them" is static throughout the round.
3. If, on a player's turn, one of the four goal coins is moved, that player loses the round.

Examples:

1. Heads slides a coin into the goal. Tails slides a coin into the goal, knocking the heads coin out of the goal. The heads coin flips over and returns to tails's bank. It is now heads's turn.
2. Heads slides a coin into the goal. Tails slides a coin into the goal, knocking the heads coin out, but then two tails coins also leave the goal. All three coins flip—heads adds two coins to bank, tails adds one. It is now heads's turn.
3. Heads is caught cheating with their finger still touching their coin as they try to flick it into the goal. Heads loses (penalty A).
4. Heads lets go of the coin properly while sliding it this time, but the coin stops outside of the goal. The coin flips and goes to tails's bank. It is now tails's turn.

Adjustments:

• If each round is too long or too short, consider shrinking or growing the goal respectively.
• Consider allowing players to have an arsenal of coins of different shapes and masses. This is more relevant than one might think. For example, a US penny will hit a US quarter and then rebound, when another US quarter will not.
