Keep the tiles
moving.
Collider is designed to be easy to begin and satisfying to master. Start with the guidance below, or email us if you run into a problem.
Choose your board
Use the board selector to switch between 4 × 4 and 5 × 5 play. Each board keeps its own best score on your device.
Undo a move
Tap Undo to reverse your most recent move. Starting a new game or changing board size clears the available undo state.
Game Center leaderboards
Sign in to Game Center in iPhone Settings, then open LeMay Leaderboards in Collider to compare scores. Scores are submitted when a game ends or you reach the target tile.
Sound and haptics
Collider uses sound and device feedback to make each move feel physical. Use the sound control in the app or your iPhone volume settings to adjust the experience.
If something isn’t working
Close and reopen Collider, confirm that iOS is up to date, and verify Game Center is signed in. If the problem continues, email us with your iPhone model and iOS version.

Clear answers,
one move away.
Does Collider require an account?
No Collider account is required. Game Center is optional and is used only for Apple leaderboard features.
Why isn’t my score on the leaderboard?
Confirm that you are signed in to Game Center and have an internet connection. Scores are submitted when your game ends or when you reach the target tile.
Are 4 × 4 and 5 × 5 scores separate?
Your local best score is saved separately for each board size. The Game Center leaderboard records submitted scores across supported play modes.
Can I restore a previous game?
Collider saves best-score information, but an unfinished board may not be recoverable after the app is removed or its data is cleared.
Does Collider collect personal information?
Collider does not require registration, show third-party ads, or use cross-app tracking. Apple may process Game Center information under your Apple account settings.
