Gomoku, Reversi, Four in a Row

Classic Board Games brings three timeless strategy games, Gomoku, Reversi, and Four in a Row, to your mobile device with offline play. Practice calm deduction against the AI or share a single phone to play face-to-face with friends in local 2-player mode. ◆ Gomoku (15x15 Board) - Black moves first, alternating turns. Connect five stones horizontally, vertically, or diagonally to win. - Renju Rules: Standard competitive rules where only Black has forbidden moves: double three, double four, and overline (six or more). Forbidden intersections are marked with an X to prevent illegal moves. A move making exactly five wins immediately, even on forbidden spots. White has no forbidden moves and wins with six or more. - Free Style: A simple mode with no forbidden moves where five or more in a row wins. ◆ Reversi (8x8 Board) - Black moves first. Trap opponent discs between yours in any direction to flip them to your color. - Show Legal Moves: An optional setting that displays dots on all valid squares where you can place a disc. - Automatic Pass: If you have no legal moves, the turn automatically passes after 1.5 seconds. - Game Over: The game ends when neither side can move or the board is full. The player with the most discs wins. ◆ Four in a Row (7x6 Board) - Black moves first, taking turns. Drop discs into columns to line up four horizontally, vertically, or diagonally to win. - Gravity: Discs drop to the lowest empty slot; full columns accept no more discs. - Draw: If all 42 slots (7x6 board) fill with no four in a row, the game is a draw. ◆ Game Modes - Play vs AI: Three difficulty levels: Easy, Normal, and Hard. AI calculations run smoothly in the background. - 2 Players (Local Pass-and-Play): Share a single device without internet or extra setup to play together. ◆ Helpful Features - Undo: Undo moves without limit. Undoes 2 moves in AI games (your move and the AI's move) and 1 move in 2-player games. - Auto-Save and Continue: Every move saves automatically to local storage. Resume your game anytime where you left off. - Game Records: Win, loss, and draw records are tracked locally by game and difficulty, and can be reset anytime. - Confirm Before Placing: Optional two-tap confirmation to preview your move on first tap (column preview for Four in a Row) and confirm on second. - Display Theme and Audio: Choose between System, Light, and Dark display modes. Toggle placement sound effects and vibration feedback. - Accessibility: TalkBack support with a Board Reader (Read board, Go to square, Last move, Threats/Legal moves), landscape/portrait modes, and display scaling up to 2.0x. ◆ Limitations - Designed for offline play; online multiplayer, user accounts, and external leaderboard servers are not supported. - Game notation export and AI move recommendations (hints) are not included. ◆ Advertising and In-App Purchase - This app is free to download and contains ads. - There are no banner ads or rewarded video ads.
