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.
All Fives profile: two receive nine tiles each, three seven, four five. Play if able; otherwise draw until a tile can be played or the yard is empty. A usable drawn tile must be played; you may choose its matching end but cannot draw again first. Only the first double is a spinner. Its first two neighbors go on the sides; only then do the other two arms open. An exposed double counts both halves. The spinner itself counts both halves until both side arms are used; empty extra arms count nothing until a tile starts them. After placing, a positive open-end total divisible by five scores that whole total. Out wins the hand; a block is won by the player or team with lowest remaining pips. Award opponents’ pips rounded to nearest five. A tied two/four-player block gives no hand bonus. For a three-player lowest tie, this digital profile rounds the third hand total first, then shares it equally, allowing half-five points. Opposite partners share scores and exclude partner’s remaining pips from their bonus. A sole leader at or above 250 in two or 200 in three/four wins immediately; do not count or play remaining tiles after an in-play win. Simultaneous tied match leaders continue into another hand until one leads alone. Out’s player leads the next hand; after a block the leader is chosen by lot.

Worked example
Score when the sum of the open ends is a multiple of five. Doubles and the first spinner affect which ends count.
