ALL-HU
Mahjong Puzzle
Where Every Hand Must Win.
You are not one player at the mahjong table. You are all of them. ALL-HU is a perfect-information mahjong puzzle. Every hand, the pool and the discard pile are dealt face up — nothing is hidden but the wall. Rearrange the tiles so every hand on the table reaches a winning shape at the same time, inside a fixed budget of moves. No dice, no opponent, no luck. Only reading the board. New to mahjong, or just want something calm? Start in Cozy Mode: large tiles, unlimited hints, and a step-by-step walkthrough that explains why each swap works — made for older players and anyone who wants an unhurried puzzle. ■ THIS IS NOT MAHJONG SOLITAIRE No tile-matching, no stacked pyramids, no pairs to clear against a timer. ALL-HU uses real mahjong hands — sequences, triplets, the pair, yaku and han — and turns them into a pure logic puzzle you solve by reading, not by reflexes. If the only mahjong you know is the tile-matching kind, this is the other kind: a strategy brain teaser for sudoku lovers. ■ HOW IT PLAYS ■ FIVE WAYS TO PLAY, 900+ LEVELS ■ NEW TO MAHJONG? START AT ZERO The course assumes you know nothing: suits and honor tiles, sequences, triplets and the pair, four melds plus one pair, then tenpai, yaku, han and special hands. Every lesson is interactive, and every answer is checked by the engine that runs the game. Already play riichi or Hong Kong mahjong? Skip it — the yaku list will look familiar. ■ BUILT TO BE FAIR ■ STRAIGHT ABOUT THE BUSINESS MODEL Free to download, and no purchase unlocks content: all 900+ levels are earned by playing — no paywall. Ads never interrupt a puzzle in progress: a full-screen ad can only appear after a win screen, and not at all in your first half hour. One optional purchase — a single non-consumable — removes every ad permanently and makes Solve unlimited. No subscription, no loot boxes, no recurring charge. The price is set by the store for your region. ■ ALSO WORTH KNOWING ALL-HU: where every hand must win.

Questions
Do I need to know mahjong?
No. The game opens with 17 interactive lessons that start at "what is this tile called". Everything after that assumes nothing.
Does it work offline?
Yes. The whole game runs offline and needs no account — nothing to sign up for, nothing to sync. Ads are the only thing that touches the network.
Is every level really solvable?
Yes. Every level ships with a solution verified by the game's own solver, and its three-star threshold is set from that level's verified solution — not from a guess.
What does the one-time unlock include?
Unlimited Solve demonstrations and no ads, permanently, from a single non-consumable purchase. It restores on your other devices signed in to the same store account.
Which mahjong rules does it use?
Standard hands — four melds plus a pair — scored on a 33-yaku han table. There is no drawing, no calling and no opponent: it is a puzzle, not a match.
Is there a mode for beginners or relaxed play?
Yes. Cozy Mode uses large tiles and text, gives unlimited hints, and walks you through every move explaining why each swap works. Difficulty rises gently — made for older players and anyone who just wants a calm puzzle.
