OffBeat — One Is Lying

New: Daily Challenge, one puzzle a day, the same for everyone, one attempt. Plus slow-motion replays of a miss, practice for your weak spot and an atlas of differences.

A field of shapes. One rule they all obey. Except one.

OffBeat is a quiet game of attention. The objects on screen share a behaviour: the same colours in the same order, the same morphing, the same orbit, the same pulse. One of them doesn't. Find it and tap it.

Early on it jumps out. Later the difference no longer fits into a glance and only surfaces if you keep watching: a colour sequence out of order, a lagging phase, a tempo six percent slower, an extra step. At high levels several groups share the field, and the odd one belongs to none. Not a reaction game, and not spot-the-difference on static pictures.

Modes

• Chain: endless. Every correct tap raises the difficulty; one mistake ends the chain. No lives.
• Quick Game: 60 seconds across five difficulties, from Easy to Master.
• Daily Challenge: one puzzle a day, the same for everyone, and a single attempt. Its own leaderboard and a streak for consecutive days.
• Practice: ten rounds on a single kind of difference, no timer. The game tells you which kind you miss most often.
• Colorblind Mode: a full separate mode with its own progression and leaderboards, where colour is never the difference - only shape, size, orientation, movement, rhythm and sequence.

Every round is checked before you see it, so the odd one is always findable. Missed it? Watch a slow-motion replay of the moment. The atlas of differences collects every way to break the rule, with a live example and your own accuracy for each.

Game Center leaderboards and achievements. VoiceOver, Dynamic Type and Reduce Motion supported - the latter calms the movement without removing the puzzle. Haptics on iPhone, sound synthesised in the app.

No in-app purchases and no accounts. Adverts only on your terms: a short video you can choose to watch to continue a broken chain. One download for iPhone, iPad and Mac.
