Each game uses a purpose-built AI engine. Our Tic Tac Toe AI on Impossible mode runs an exhaustive search — it evaluates every legal board position from the current state to the end of the game, guaranteeing perfect play. On Easy mode it uses a simplified engine that deliberately misses some optimal moves, creating winnable positions for new players.
The Connect Four AI combines search with pruning techniques to look multiple moves ahead. It scores each column by how much it contributes to building chains and controlling the center. On easier difficulties it uses a shallow heuristic focused on immediate threats. On Impossible it searches deeply into the game tree, constructing traps and blocking yours simultaneously.
Our Gomoku AI uses line-tracking to evaluate the 15x15 board. It scans every possible line of five — horizontally, vertically, and diagonally — scoring each by how many stones are yours, how many are the opponent's, and how many slots are open. It prioritizes blocking your strongest threats before building its own attack, creating games that feel patient and methodical rather than purely reactive.
Every engine runs client-side in the browser. There is no server lag — moves are calculated in milliseconds using TypeScript game logic that runs entirely on your device.
Also known as five in a row online, Gomoku challenges you to place five stones in a continuous line on a 15x15 grid. The AI evaluates open threats and blockades to create a balanced challenge. Start on Easy to learn pattern recognition, then push to harder levels where the AI's defensive play becomes more sophisticated. Every game improves your ability to think ahead and recognize formations.
The vertical drop mechanic adds a spatial reasoning layer to classic four-in-a-row. Gravity forces you to consider column stacking and bottom-up chains. Our Connect Four AI adapts its minimax depth to your chosen difficulty — Easy for casual play, Medium for balanced strategy, and Impossible for a near-perfect opponent that punishes every mistake. Building overlapping traps is the key to winning.
The perfect entry point for AI gaming. Tic Tac Toe's small 3x3 board makes it solvable — on Impossible difficulty the AI plays a perfect game using exhaustive minimax search. You cannot win, but you can learn to recognize forks, blocks, and forced draws. Easy mode lets you practice openings and experiment with different strategies. It is the fastest way to understand how deterministic AI works.
All three games are free, run entirely in your browser, and require no account. Choose your game, pick a difficulty, and start challenging the computer in seconds.
Playing against deterministic AI has a unique advantage over human opponents: the computer never makes mistakes due to emotion or distraction. Every move is calculated. This means every loss teaches you exactly where your strategy broke down. Review your games mentally, identify the move that gave the AI an opening, and adjust your approach for the next match.
Over time, playing against strong AI opponents builds pattern recognition and forward-planning ability. These skills transfer directly to chess, Go, and other turn-based strategy games where thinking ahead determines the outcome.
