Watch recorded matches unfold one move at a time
Completed games are saved with their full move history — whether they were played by a registered member or a guest — and any of them can be played back here. Board playback is available for Connect 4, Checkers, Reversi, Mancala, Gomoku, Hex, Battleship and Ultimate Tic-Tac-Toe; a few of the newer games record their moves but do not have a playback board built yet. Use the filters to pick a game, then open a replay to step through it with play, pause, variable speed, and move-by-move navigation.
Finish a game of Connect 4, Checkers, Reversi, Mancala, Gomoku, Hex, Battleship or Ultimate Tic-Tac-Toe and it will show up in this list for anyone to watch.
Play Connect 4Most games are not lost at the moment they look lost. By the time a position feels hopeless, the mistake that caused it is usually five or ten moves in the past, and in the heat of play almost nobody notices it happening. Replays exist to find that moment.
Stepping through a finished game slowly changes what you can see. The move that felt natural at the time — taking an obvious capture, blocking the threat directly in front of you — is often the exact point where the game turned. Watching it back without the pressure of a clock or an opponent waiting makes those turning points much easier to spot.
A replay stores the sequence of moves and the final result. It does not store anything else about the player. Games played while logged in are attached to that username; games played as a guest are saved as anonymous. Either way the match becomes part of the public recent-games feed, which is worth knowing before you play — other people can watch your games, and you can watch theirs.
Open any replay card and the board reconstructs itself from move one. The controls let you step forward and back a single move at a time, play the whole game automatically at half, normal or double speed, and jump around using the progress bar. Stepping manually is usually more instructive than watching it play: pause before each move, decide what you would have done, then advance and compare.
A method that works well: play the replay through once at normal speed to get the shape of the game, then step back to the point where the result stopped being in doubt. Rewind a further five or six moves from there. Somewhere in that window is the decision that actually mattered. Ask what the alternative was and why it looked less attractive at the time — that reasoning is the thing worth fixing, not the individual move.
Losses are more useful than wins here. A won game mostly confirms what you already believed; a lost one shows you a hole in it. Watching other players' games against the AI is also worth your time, especially in games such as Reversi where strong play looks counter-intuitive until you have seen it work.
Replays show you what happened. Coach mode tells you what the engine thought about it — running an evaluation over each position and marking exactly where the advantage swung, along with what the stronger move would have been. If a replay leaves you unsure why a game went wrong, the coach review usually answers it.
