You must play a move in both chess and Gomoku within the shared 7-second limit.

Chess win +50 points · Gomoku win +10 pointsThis is an endless challenge. Winning restarts that board and raises the difficulty from Easy → Normal → Hard. Play continues at Hard and ends only on a timeout or defeat.

In Gomoku, you always play black stones and the computer plays white stones. The colors stay the same in every new game.

Start with your first chess move. Choose 7, 5, or 3 seconds first. The game starts as soon as you make an actual chess move. You can play Gomoku after that.

One timer, two moves. A chess move switches to Gomoku, and a Gomoku move switches to chess. After the computer replies and you can play again, the selected time limit starts afresh.

When computer waiting ends and player input becomes available, the selected time limit starts in full.

Win to keep going. Only the board you win resets, and your total score is retained. Each win raises the computer's level from beginner to intermediate to advanced. Play continues at advanced level. A draw resets only that board without awarding win points.

Game over: The whole game ends if you fail to make both moves in time or lose to the computer on either board. The computer never makes your moves for you. The time limit keeps running even if you switch tabs.

Chess: You start as White. Standard rules apply, including check, checkmate, castling, en passant, promotion to your chosen piece, and draws. Only legal moves are allowed.

Gomoku: You start as Black on a 15×15 freestyle Gomoku board. Connect five or more stones horizontally, vertically, or diagonally to win. Forbidden moves such as double-three do not apply.

For rankings, the server verifies moves, time limits and scores. You can keep playing if the connection is lost, but that game cannot enter the rankings.
