Flang is a board game similar to chess or shogi but differs in some special rules. If you like chess or other board games, you might want to try this one.

The unique thing about flang is the freeze mechanic. Once you move one of your pieces, it cannot be moved in your next turn because it is freezed except for the king.

- Flang TV: see other people play Flang
- Profile: watch played games
- Analysis board: reinvestigate your games, optionally with computer hints
