Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
A hidden rule in every grid. Find the tile that breaks it - 100 levels, arcade runs, endless lives, and a daily puzzle the whole world shares.
Every grid hides a rule - one tile breaks it. Can you spot the odd one out?
Odd One is a calm, minimalist brain-training puzzle. Look closely: shapes, colors, sizes, counts. Three of a kind follow the pattern, one quietly doesn't. Tap it.
FOUR WAYS TO PLAY
• Classic - 100 handcrafted and generated levels, no timer, pure logic. Grids grow up to 5×5 as you climb.
• Arcade - a 60-second time bank. Solving adds seconds, mistakes cost them. How far can you go?
• Endless - three lives, no clock. Pick your difficulty and settle in.
• Daily - five puzzles, the same for everyone on Earth, once per day. Your time is your score. Keep the streak alive.
MADE WITH CARE
• No ads. No tracking. No account. Completely free.
• Optional Game Center leaderboards and iCloud sync
• English, German, French, Italian, Spanish
• Light & dark mode, subtle haptics, calm piano soundtrack
• Color-assist mode for color-blind players
• Works beautifully on iPhone and iPad
If you enjoy Odd One, you can leave a small tip - it unlocks nothing, it just keeps the game free for everyone.
An earls studio game.
