Gravity Four

About this game

Connect Four with gravity. Pick a column and your piece falls to the lowest empty square. Line up four in a row — vertically, horizontally or diagonally — and you win. That's the whole game.

■ Choose your board
Four sizes, from the classic 6x7 up to a 10x12 monster. A wider board means more to read and a genuinely different game. Four in a row wins on every size.

■ Play solo
Three difficulty levels. "Hard" searches ten moves ahead and will almost certainly beat you. "Easy" is tuned so a beginner can win — but it still blocks your threats.

■ Play with a friend on one device
Pass the phone back and forth. No network, no waiting for an opponent — it works on a plane.

■ Play with a friend who isn't with you
Create a six-character passphrase and send it to them. When they type it in, the two of you are matched. No sign-up. Passphrases are never listed publicly, so a stranger cannot wander into your game.

■ Play the world
You are matched automatically with someone who picked the same board size. No sign-up. Their moves appear on your screen instantly.

■ Built to feel good
- Tap a column, or drag sideways and release
- A ghost piece shows where it will land before you commit
- Pieces accelerate as they fall and bounce on landing
- Only the winning four light up — everything else dims, so you can see exactly where it was decided

No ads. No in-app purchases. No account. Open it and play.

■ Data
Online play uses an anonymous identifier, the list of columns played, and — if you use one — your six-character passphrase. No name, email, phone number, device identifier or location is collected. It is used only to match you with an opponent. Match data is deleted after two hours and unused identifiers after 30 days. Playing the computer or a friend on the same device creates no data at all.
