A battle is more than a timer. The result records the board, participants, clear status, move count, elapsed time, and final decision reason.

Players can start when ready, which makes battles easier to share with a friend while still preserving the same-board comparison.

Once the whole match ends, use Practice this board to study the same puzzle without changing the official result. Records preserves the final moves, times, and decision reason; it does not replay either player's route.

One player creates a private room and shares the invite code. Both players solve the same hidden board, and each player can start when ready.

No. Each participant starts when ready within the room rules. The board is revealed only when that player starts, and each official timer runs from their own start.

No. The room checks for player status and result updates automatically while the page is visible and online. If the connection fails, it keeps the last known state and offers a manual refresh; returning to the page or reconnecting also checks for updates.

Resume restores an active attempt in the original browser when its saved moves are available; the official timer continues from the original start. Once the whole battle has ended, Practice this board opens the same puzzle with learning tools. Finishing your own run does not unlock practice while the match is still active.

Completed battles compare clear status first, then moves and time. Resignation, timeout, and draw conditions are recorded so the result remains transparent.

Completed battle records are available from the Records page together with practice and daily history.
