Flash

A visual memory game. Squares flash, then vanish. Tap them back.

Flash is a visual memory game. A grid appears, a few squares light up for a split second, and then everything goes blank. Your job: tap back every square that was lit. It takes a second to learn and a long time to get good at.

Every level adds squares or grows the grid, from 3×3 up to 7×7, and the flash gets a little quicker. Then, from level 8, the board starts to turn after the flash, so you have to rotate the pattern in your head too.

Flash is part of Unrot, a series of twenty short games that each put one mental skill to the test: memory, attention, speed or logic. Twenty games. Zero brainrot.

How to play

  • Watch the squares that light up.
  • When they vanish, tap every one that was lit, in any order.
  • A wrong tap is a strike. Three strikes and the run is over.
  • From level 8, a label warns you when the board is about to rotate or mirror. Tap where the squares landed, not where they were.

Scoring

  • Your score is the level you reach.
  • A level cleared with no wrong taps is perfect, and perfect levels break ties.
  • Play the Daily for one scored run on the same boards as everyone else, and keep your Unrot streak alive.

Tips

  • Don’t memorize squares one by one. See the shape they make together: a line, an L, a corner cluster.
  • Tap the squares you’re sure of first, then think about the rest. There’s no timer.
  • On a turn, track one corner of the shape and let the rest follow it.
  • A mirror only swaps left and right. Top stays top.

FAQ

Is Flash free?

Yes. Flash is free to play in your browser on desktop and mobile, with no download and no account.

How does Flash work?

A grid appears and a few squares light up for under a second. Then they all go blank, and you tap every square that was lit. Clear the board to reach the next level, which has a bigger grid and more squares.

What happens when the board turns?

From level 8 the board can rotate a quarter turn, mirror, or later flip upside down right after the flash. A label warns you while the squares are lit, so you can turn the pattern in your head and tap where the squares ended up.

How many mistakes can I make?

Three. Every wrong tap is a strike, and the round keeps going. A round with no wrong taps counts as a perfect level, which breaks ties between runs that reach the same level.

What is the Daily?

Once per day (UTC) everyone gets the same boards. Your first Daily run is scored, and playing any Unrot Daily keeps your Unrot streak going. After that you can practice the same boards as much as you like.
