Mahjong Handle

Mahjong Handle takes the Wordle formula and swaps letters for mahjong tiles. The answer is a 14-tile winning hand from riichi mahjong, and the game tells you the round wind, the seat wind and whether the hand was won by ron or tsumo, since those affect which yaku are possible.

You build each guess from an on-screen keyboard of characters, circles, bamboo, winds and dragons. Guesses must be complete winning hands with at least one yaku, with the tiles sorted by number and suit, except the final tile, which is the winning tile and sits in its own column. After each guess, the tiles change colour to show whether each one is in the hand and in the right spot, in the hand but in another spot, or not in the hand at all.

Everyone gets the same hand on the same day: the game counts the days since 2 February 2022 and picks the matching hand from its list. The list holds 10,027 hands, so the cycle will not come round again for more than 27 years. The game credits Wordle as its inspiration and links its open source code under the GitHub name yf-dev.

It suits riichi players who know their yaku and want a daily test of hand shapes, and it is a fair challenge for learners who want to practise reading waits.

There is no account and no ad on the page. A statistics panel keeps your win distribution and streaks in the browser, a share button copies your result grid, and a dark theme is one tap away. On a phone the tile keyboard fits under the six rows, and on a desktop you can also type hands in the usual notation (m, p, s and z).
