Every game kept棋譜
A finished game is filed with its stones in order, and kept for good: no move history here goes missing after a few years. Replay it, send a friend the exact move you mean, and see how a player's rating moves.
Fork any position分岐
A close game deserves a second try. From any move of any game, start another game at exactly that position, against the same opponent, and play both.
Where this comes from由来
For years the founder of this site and his parents played across two households on the great turn-based sites of the early web, ItsYourTurn and GoldToken — Othello with his father, and five-in-a-row, Pente and Othello with his mother — sometimes hours a day, dozens of games open at once, and memberships bought to lift the daily cap on moves, because twenty was never going to last until lunch. Those sites understood that a game between people who love each other does not need to be fast; it needs to be kept. Itsutsu is a continuation of that, and a tribute to it.
The family is half Japanese, and the games came with the heritage. Five in a row has been played on go boards in Japan since the Heian period, a thousand years ago, and the name of this site is just the Japanese for the number — 五つ, five stones.
