Two tile pictures sit one above the other with a few quiet differences. Tap each one before you run out of lives. Every round hides more.

A real run of the game, recorded with captions and no sound.

Two six by six pictures appear, an original on top and a changed copy below.
Find the tiles that are different: a missing shape, a new shape, a different colour or a different outline.
Tap the tile on either picture. A correct tap turns it green on both.
A wrong tap costs a life. Find every difference to clear the round and earn a bonus. Three lives per game.

Controls: mouse or touch. Made by CalcoTools.

Scan one row at a time instead of the whole picture at once.
Check empty tiles first. A tile that is blank on one side is the easiest difference to miss.
Colour changes to a similar shade are common. Compare corners and edges carefully.
Later rounds hide up to seven differences, so keep a count and stop tapping when you have them all.
