Three moments in time, read left to right. The number below each grid is the step.

One numbered tile lights up at a time. Keep a short ordered phrase in mind, such as “top left, center, top left”. After the flashes stop, tap that same route.

Three moments in time, read left to right. The number below each grid is the step.

The return visit counts

Tile 1 flashes, then tile 5, then tile 1 again. Tap 1, 5, 1. Tapping just 1 and 5 would leave the third position blank.

Undo removes your last tap. Clear removes the whole answer. You can check as much as you remember without filling every position; each correct tile in the correct position earns a point.

1, then 5, then back to 1. Three flashes need three taps.
