Grid Flash

Squares flash on a grid for a moment. Tap them all from memory. Every round adds more squares and the grid grows as you improve.

How to play

  1. Press Show pattern. Some squares light up for a short time, then go dark.
  2. Tap every square that was lit. You do not need to follow any order.
  3. A wrong tap adds a mistake and shows the pattern again so you can try the round once more.
  4. Clear every round to finish. Rounds get harder with more squares and bigger grids.

Tips and strategy

  • Group the lit squares into shapes such as a line, an L or a corner instead of remembering each one on its own.
  • Look at the pattern as a whole picture rather than scanning square by square.
  • Use the first moment of the flash to find the extremes, such as the top-left lit square.
  • Stay relaxed. Replays are free apart from the mistake count.

FAQ

How long is the pattern shown?
The flash lasts a little longer for every extra square, starting at about one and a half seconds.
Is the daily pattern the same for everyone?
Yes. All six daily rounds are built from the UTC date.
Does the order of my taps matter?
No. Only the set of squares you tap has to match.
