Yahtzee is a simple dice game you can play here with 4 other members at a time. Each turn, you roll five dice, keep the ones you like, and roll the rest up to two more times. Then you pick a box on your scorecard and take whatever that roll is worth.
The whole card is visible while you play, so everyone at the table can follow along. When the game is finished, the scores can be posted to a thread, and you can also put [yahtzee=id] in a post if you want to show the card somewhere else on the board.
You can start a new table or join one that is already waiting.
