About this game

Two classic board games in one app: Connect Four and Tic-Tac-Toe! Challenge an Artificial Intelligence, play a friend on the same device or take on real opponents online - anytime, anywhere, and single-player even offline.

🎮 HOW TO PLAY
Drop your red discs into a 6×7 grid. Be the first to connect four of your color in a row — horizontally, vertically, or diagonally — and you win!

🤖 FIVE DIFFICULTY LEVELS
• Beginner - For your very first games. The AI plays random moves.
• Easy - Perfect for children. The AI looks one move ahead.
• Medium - A genuine challenge. The AI thinks two moves ahead.
• Hard - For experienced players. Look-ahead alpha-beta search.
• Expert - Can you beat the AI? Minimax at depth 10 — near-perfect play.

⭕ TIC-TAC-TOE - THE SECOND GAME
Three in a row on a 3×3 grid, with its own menu and its own achievements. Play solo against the AI across three levels up to "Unbeatable", two players on one device, or online against a friend. Switch between the two games with the button at the top left.

👥 2-PLAYER MODE (PASS & PLAY)
Play together on one device — in Connect Four and in Tic-Tac-Toe! Take turns and go head-to-head — perfect for friends and family, no internet needed.

🌐 PLAY ONLINE
Challenge real opponents worldwide — in both games! Auto-matchmaking finds you a match in seconds, or invite a friend with a link or a share code. 20-second move timer, resign or ask for a rematch anytime. Report or block players you'd rather not face again.

📅 DAILY CHALLENGE
A fresh Connect Four puzzle every day: every player worldwide gets the same preset starting position. Can you do better than yesterday?

🔥 STREAKS
