## What is Odd One!?

Find the single tile that does not belong—and tap it.
That is all it takes.

Odd One! is a fast, addictive observation puzzle that is easy to understand but difficult to master.

Start with just four tiles. Every correct answer immediately brings up a new puzzle, while the number of tiles and the difficulty continue to increase.

The difference might be a symbol, color, size, rotation, opacity, or font weight. As your score rises, those differences become increasingly subtle—until you are searching for one tiny detail among 100 tiles.

Features

• Simple one-tap gameplay
• Instant transitions with no waiting
• Puzzles ranging from 4 to 100 tiles
• Randomized objects, colors, and positions
• Increasingly subtle visual differences
• Personal best score tracking
• Game Center leaderboards and achievements
• Support for English and Japanese
• Perfect for quick play sessions

Easy to learn. Difficult to master.

How many odd ones can you find before your focus breaks?
