Isochrone - Timing Puzzle
A puzzle of perfect timing
Only for iPhone
Free · Designed for iPhone. Not verified for macOS.
iPhone
Land every branch on its exact beat. 367 puzzles + a daily puzzle to challenge your friends. No ads ever.
A pulse leaves the source and moves one cell per beat. Your job is to get it home to its receiver, on exactly the beat it is waiting for.
Not one beat early. Not one late.
You do it by laying pieces on the board:
• Mirrors turn the pulse.
• Splitters break one beam into two or three, and now every branch has its own deadline to meet.
• More pieces will be revealed as you progress.
Every piece in your tray is needed, but if you can solve it with pieces to spare, you get a bonus added to your score.
DAILY PUZZLES
Compete with friends and global players with a daily puzzle (puzzles are playable for free, leaderboard requires full game unlock)
An overall game leaderboard shows where you stack up against other players on the core gameplay.
367 SOLVER-VERIFIED LEVELS
Every board is proved solvable by a solver before it is released. Difficulty comes from the shape of a puzzle, not from burying you in pieces.
Nine zones, each introducing one idea and then asking harder questions about it. A branching map lets you pick your own route through them.
SOLVE IT IN YOUR HEAD
Clearing a board on the first run is worth more. Reasoning it out beats guessing.
PLAYS ANYWHERE
Every level ships inside the app. No loading, no downloads, no connection - it works in full on a plane or underground.
FREE TO START
No ads. No timers, no lives, no energy, no currency. The first 2 zones are free; a one-time purchase unlocks all 367 levels and the daily leaderboard, forever.
