Rules & objective
Uses all 28 double-six tiles, including double blank. First leader is chosen by lot or your selected seat; any own tile may lead. Match identical pips, including blank with blank. Block and Draw have only two ends; doubles are crosswise but never spinners. Choose a tile/end or a draw preview, then confirm. No pass if a legal tile must be played or usable drawing remains. Blocked means every seat passes in succession. End-of-hand tiles are revealed for scoring; otherwise only your hand is visible. Local handoff hides all private tiles until Show my tiles. Computer and hints use only own hand, public layout and unknown-tile possibilities, never future yard or opponents’ private tiles. Undo/redo restores real actions; computer undo includes responses after your last action. Restart repeats this deal/settings; New changes the deal. Rules and score details pause computers. Swipe pans without acting; zoom and rotation retain game and preview. This is untimed casual play with automatic scoring, not optional manual muggins penalties.
Block profile: two receive seven tiles each, three/four receive five. The remaining yard is never drawn. If unable to place, pass. A hand ends when someone empties their hand or all are blocked. Count each remaining hand’s pips: a unique lowest player scores all opponents’ pips minus their own; a tie scores nothing. First to at least 100 for two or 61 for three/four wins. The next hand’s leader rotates from the previous leader, even after a block.
