Odd One Out is a visual observation puzzle where you must find the ONE item that is different from all the others in a grid. The items may differ by color, shape, size, or pattern. As levels progress, grids get larger and differences get subtler.

How many levels are there?

There are 30 handcrafted levels across 5 difficulty tiers: Tutorial (3x3), Easy (4x4), Medium (5x5), Hard (6x6), and Expert (7x7). Each tier has 6 levels with increasing challenge.

You earn 3 stars for solving quickly (under 50% of the time limit), 2 stars for moderate speed (under 80%), and 1 star for completing the level. Time-based tiers reward speed!

Is Odd One Out different from Spot the Difference?

Yes! Spot the Difference shows two images and you find ALL differences between them. Odd One Out shows a single grid of items where exactly ONE is different — you must identify and tap that single odd item.
