About this game
Connect Four, the way you remember it. Drop discs on a 7×6 grid, opens instantly, plays fully offline, and asks for nothing — no ads, no sign-in, no internet permission at all.
Play a friend on one phone, or take on the CPU at three strengths.
TWO WAYS TO PLAY
• Pass and play — two people share one device, taking turns dropping discs.
• Versus CPU — you go first, the engine replies.
THREE CPU LEVELS
• Easy — searches ahead but throws away some of its best moves, so a beginner can win
• Medium — solid four-ply search, punishes obvious mistakes
• Hard — six-ply negamax with alpha-beta pruning, favours the centre column and reads ahead for forks
The CPU thinks on a background thread, so the board never freezes.
EVERY RULE, PROPERLY
Discs fall with real gravity — drop in a column, watch it settle on the lowest open slot. Four in a row wins, horizontal, vertical, or either diagonal. A full board with no line of four is a draw, called out clearly.
HELP WHEN YOU WANT IT
Tap a column to drop, tap again to change your mind before it lands. Stuck? Hint names the strongest column to play right now. Undo takes back your disc — and against the CPU, its reply too, so you land back on your own turn.
SIX THEMES
Classic, Ocean, Midnight, Bloom, Aurora and Black. Several are true dark themes for late-night play, and Black is near-OLED-black. The theme recolours everything, status bar included.
BUILT TO FEEL GOOD
Discs drop with weight, the winning line lights up, subtle haptics on every tap, plus optional tones you can leave switched off.
NEVER LOSE A GAME
Leave mid-match — a call, a notification, a closed app — and the board, whose turn it is, and your settings all come back exactly as you left them.
STATISTICS
Wins, losses and draws against the CPU, tracked per difficulty and resettable whenever you want a clean slate.
PRIVATE BY DESIGN
No internet permission. No ads. No accounts. No analytics. Nothing to collect, because nothing leaves your device. Works fully offline, on a plane, in the underground, anywhere.
Whether you are teaching a kid their first strategy game or looking for a quick match against a CPU that actually plans ahead, this is the Connect 4 board that gets out of your way and just lets you play.
