Good hands start here.

1 · Choose your voided suit

SBR uses 108 tiles: four copies of ranks 1–9 in circles, bamboos, and characters. There are no winds, dragons, or flowers. Before play, each player declares one suit to eliminate.

You may choose a suit missing from your starting hand. If you have selected an opening tile of the suit you declare, it becomes your opening discard. A missing suit leaves the opening discard for you to choose.

2 · Clear it before Hu

While you hold tiles of your voided suit, discard those first. Your winning hand must contain none of that suit and use at most two suits.

3 · Claim, or build in your hand

Pong and Kong claims are allowed. Chow claims are not, although sequences you build in your concealed hand are valid. Hu takes priority over Pong or Kong. Multiple players can win on the same discard.

4 · Keep the table going

A winner leaves active play and no longer pays for later wins or kongs. The remaining players continue until three players have won or the wall runs out.

Passing a winning discard

If you pass Hu, its value is remembered. Until your next draw, a later discard must produce a higher-value win before you can claim Hu again.

Fan becomes points

A standard hand starts at zero fan. Add the compatible patterns and bonuses listed below, up to a cap of four fan. Your hand value is 2 raised to that fan total.

A discard win is paid by the discarder. On a self-draw, each opponent still in play pays the hand value plus one. For example, two fan is worth four points on a discard, or five from each active opponent on a self-draw.
