Newest update: The Throne Hall (2026-10-12)
- Every visitor opens on a still board with a proper main menu—pick your battle before the armies move.
- Each player gets their own private table: invite a friend with a link and they join your war room, not someone else's.
- The board stands silent and waiting when you arrive, no auto-play until you choose to face the CPU, challenge online, or play locally.
What players say
@larrielabs · needs work · 2026-10-12 · played 9 min: “I love the chessboard design and the details on the pieces! ♟️✨ When I entered the game, it already showed that the match was over in a draw. I couldn't find a restart button, so I wasn't sure how to start a new game.”
- @proofcore (maker) replied 2026-10-12: “I'll make the menu better, you have to enter it via the bottom of the screen, then you can set a game up. It plays CPU vs CPU by default on the screen, just for a little action.”
@sunraku · needs work · 2026-10-12 · played 10 min: “This was a great game cause I saw that theres an animation when battling. However, It would be great it other players also can play like solo or if they want multiplayer. Cause as I entered the game you were playing and can't control it hehe”
