Inside Collider
Clean by design.
Hard to put down.
Collide
Make one move. Change everything.
Learn
Simple rules. No instruction manual.
The whole idea
One swipe.
Every tile moves.
Matching numbers collide and become something bigger. The rules fit in one sentence. Finding the next move can take considerably longer.
16+16→32
Two boards. Two targets.
Play the classic 4 × 4 board and chase 2048, or open up the 5 × 5 board and push toward 4096.
A new board every day.
Daily Challenge gives every player the same starting board—one fresh test of strategy each day.
Undo without judgment.
Take back your last move when the board turns against you. Or leave Undo untouched and chase a harder achievement.
Compete through Game Center.
Climb the leaderboard, compare high scores, and unlock achievements from First Contact to true mastery.
Every collision feels physical.
Smooth motion, responsive sound, and precise haptics give each merge a satisfying sense of weight.
No ads. No timers. No noise.
Collider stays focused on the puzzle. Play at your pace without interruptions or artificial pressure.
Your board. Your pace.
No registration.
No tracking.

A few clear answers,
then back to the board.
How do I play?
Swipe up, down, left, or right to move every tile. Two matching numbers merge when they collide. Keep making space until you reach the target—or run out of moves.
What is Daily Challenge?
Daily Challenge creates one shared 4 × 4 board each day. You can leave and return without losing the day’s board.
Are 4 × 4 and 5 × 5 games saved separately?
Yes. Collider preserves each board independently, including its score and current tiles, so changing modes does not erase your other game.
Why isn’t my score on the leaderboard?
Make sure you are signed in to Game Center and connected to the internet. Collider submits scores when a game ends or you reach the target tile.
Does Collider collect personal information?
No. Collider does not require registration, show third-party ads, or use cross-app tracking. Apple handles optional Game Center activity under your Apple account settings.
What happens after I reach 2048?
That would spoil the surprise. Reach 2048 on the 4 × 4 board and Collider will take it from there.
