Odd One!
Read full descriptionHide full description
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?

Verdict
The clearest difference is in-app purchases: Odd One! at none against Hidden Birds's 3. Hidden Birds's advantage is ads (none vs shown) and iOS requirement (15.0 vs 17.0). On price and device support there is nothing between them.
