The game is played on a 19x19 board. Opponents take turns: one plays with white stones, the other with black. The objective is to create a sequence of 5 or more stones of your color in a row, or to capture 10 or more of the opponent’s stones. Capturing occurs by surrounding exactly two of the opponent’s stones on both sides. It is allowed to surround multiple pairs of stones from different sides simultaneously. Stones are removed only once per turn, so you may place stones in an already surrounded area.
To play online with real players, as well as online bots, go to the "tables" tab, select a table that suits your parameters and join the game. You can also create your own gaming table with the desired settings by clicking the "create game" button. In training mode, you can play offline with yourself or with the computer. The more time you give the artificial intelligence to think, the better it will play. In addition, if the game is new to you and you want to understand what strategy and tactics to follow, you can choose a CPU vs. CPU game and watch the process.
If it is obvious to you what your opponent should do next, and you already have an answer, you can, on your opponent's turn, continue the game by making moves for both your opponent and yourself to an unlimited depth. As long as your opponent's actual moves coincide with those you made on the board, your moves will be executed instantly without losing time. If you also predicted the subsequent moves correctly, they will also be executed instantly. If your opponent's move differs from the predicted one, the position will be updated, and you will simply continue the game as usual. To cancel planned moves, simply click on an empty space on the board, or make an illegal move.
