The Odd Stair

Memory · Odd one out

Every stair looks right. One is a single step off.

Count the steps on one stair. Every stair has the same count except one. Tap the stair with one step more or one step fewer. Guess wrong and both stairs number their steps so you can compare. Ten levels, and the grids get bigger and the stairs get more steps. From level 5 some stairs climb left. From level 7 the stairs come in different heights, so a taller stair is not the odd one. Only the step count is different. Try to finish all ten with as few wrong taps as you can.
