About This Demo

Mahjong with nothing hidden

In ALL-HU you see the whole table — every hand, the discards, the entire wall. Victory demands more than one win: plan draws, discards and yaku so that two, or even four, hands each reach a winning "Hu" in a single flawless sequence.

AI Generated Content Disclosure

The developers describe how their game uses AI Generated Content like this:

Some of this game's art and audio were created with generative AI tools, then selected, edited and assembled by the developer: the ink-wash illustrations and character portraits, part of the interface artwork, and the background music. The store page artwork and the trailer were produced the same way. Everything ships as fixed, pre-rendered assets. The game generates no content while you play and connects to no AI service. Puzzle levels are built and verified by our own deterministic mahjong solver, not by AI.
