Memory Sequence

How to play

Four colored squares light up in a sequence. Watch it, then tap the squares back in the same order. Every round you survive adds one more step to the chain, so a level eight run means holding eight colors in your head at once. One wrong tap ends the game, and your best level is saved.

Tips

• Say the colors to yourself as they play. "Red, red, blue" sticks far better than a silent picture.
• Chunk the sequence into groups of three or four, the same trick that makes phone numbers memorable.
• Let the whole playback finish before you move. The game only accepts taps once it hands you the turn.
• Rhythm is memory too. Many players recall the beat of a sequence more reliably than the colors themselves.

The game this is based on

Four coloured squares lighting up in a growing sequence is the format made famous by Simon, the electronic game released in 1978. It has stayed popular for nearly fifty years because it is a clean test of sequence memory: not where things are, but in what order they happened. Every round replays the whole sequence with one new step added, so the difficulty grows linearly and your limit shows up as a hard wall rather than a gradual fade.

The classic result on tasks like this is that most people can hold around seven items, give or take two. A level eight or nine run is a genuinely good result, and people who go well past that are almost always using a memory technique rather than raw capacity.

Going further than seven

• Say the colours. Red, red, blue is a phrase, and phrases are much easier to hold than a sequence of flashes.
• Group them. Red red blue, green red is two chunks, not five items, and chunks are what your memory actually stores.
• Notice repeats. Two of the same colour in a row is a single event to remember, not two.
• Replay the sequence in your head once before tapping. It is cheap and it catches the step you were about to drop.
• The sequence is not random every round, it is the same one with a step added. Only the last step is new, so that is where your attention should go.

Common questions

What is a good level to reach?

Most people manage around seven steps. Eight or nine is a good result, and going well beyond that usually means you are grouping or naming the colours rather than remembering raw flashes.

Is the sequence different each round?

No. Each round replays the same sequence with one more step added at the end, so only the final step is new.

Does one mistake end the game?

Yes. One wrong tap ends the run, and your best level is saved on this device.
