Six games, one board culture
Each one teaches a different way of thinking — and every one is playable right now, no account required.
Xiangqi
A river cuts the board in half. Cannons only capture by jumping over a screen. The two generals may never look at each other down an open file.
Play XiangqiGo
You surround territory instead of capturing a king. Still played under essentially the same rules it had two millennia ago.
Play GoReversi
Flip the board in your favour. A handful of stones can swing the whole game — easy to learn, brutal to master.
Play ReversiChess
The western classic, fully playable: castling, en passant and promotion, against a sharp alpha-beta engine. One board, infinite lines.
Play ChessTsumego
Go life-and-death puzzles. One correct move captures the group — train the reading that wins real games.
Solve TsumegoEighteen rungs, borrowed from the real thing
Chinese board culture ranks players in grades and dan, not in bronze and platinum. We kept that, and mapped it onto a rating that actually moves when you win.

What we actually built
Online games are refereed server-side
Every move in a friend match is validated by the server before it lands on either board. A patched client cannot invent a win.
The engine runs in your browser
Our Gomoku opponent searches with alpha-beta pruning under a hard 500 ms budget, on your machine. No round trip, no queue, no rate limit.
Written in five languages, not poured through a translator
English, 中文, Español, 日本語 and Português do Brasil. Rules, tooltips and error messages included — not just the marketing page.
