The whole idea
Slide. Merge.
Collide.
Matching numbers become something bigger. Pulsing hints can reveal the next collision, but choosing the best move is still up to you.
16+16→32
Two boards. Your choice.
Play 4 × 4 and chase 2048, or spread out on 5 × 5 and aim for 4096. Each size keeps its own saved game.
See your next merge.
Pulsing hints illuminate matching tiles and show where they will combine, with a touch of gold to guide the move.
Three hints. Three undos.
Every game gives you room to rethink. Your remaining hints and undos are saved when you leave and return.
A fresh challenge, every day.
Take on changing tile, score, and merge goals. Build your completion streak and revisit recent challenges.
Satisfying from the first swipe.
Smooth slides, springy merges, layered sound effects, and responsive haptics bring every collision to life.
Pick up. Play on.
Games save automatically. Play offline, choose Light, Dark, or System appearance, and adjust sound, haptics, and calmer effects.

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, then keep going if you want a higher score.
What is Daily Challenge?
Daily Challenge gives players one shared board with a changing tile, score, or merge goal. Complete challenges to build a streak and track recent results.
How do hints and undos work?
Each new game begins with three hints and three undos. Hints pulse matching tiles and show the next merge. Collider saves the number you have left when you leave.
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.
Can I change the appearance and effects?
Yes. Choose Light, Dark, or System appearance, and adjust sound, haptics, and calmer effects in Settings.
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.
