9 score pads and helpers for the games where the adding up is the hard part. Each follows the rules on its game page, opens with a sample game so you can see how it works, and keeps your game in this browser if the page reloads. Nothing is sent anywhere.
Roll up to 12 dice of any common size. Hold dice between rolls and keep a running history.
Which rules they use
Each one scores the most common US version of its game, the same version set out on the rules page, and has switches for the house rules that groups really do disagree about: three 1s at 1,000 or 300 in Farkle, the crib flush in cribbage, blind nil and bags in Spades, defending alone in Euchre, and mini buncos in Bunco.
If you'd rather use paper
Every game has a one-page sheet with the setup, a turn and the full scoring table. See printable rules.
