Getting into Simon Deep

Each level adds one step to the light pattern, and the playback gets faster as the level climbs. You watch, you repeat, and one wrong tap ends the run. The patterns that speed up every level, down to 340 ms per flash, so late rounds feel less like a memory game and more like a reflex test.

Why Simon Deep sticks

It suits anyone with a queue to wait in or a kettle to watch: students between classes, commuters, parents stealing ten quiet minutes. There is no meta-progression to lose and nothing to catch up on - a week away costs you nothing but a little sharpness.

How to play

1. Press play and watch the pads flash in order.
2. Tap the same sequence back to clear the level.
3. Each level adds one more step to the pattern.
4. One wrong tap ends the run - your best level is saved locally.

Tips and strategy

• Keep your eyes on the pad you always miss; it is usually the same one.
• Ignore everything except the newest step when replaying a long pattern.
• Play with sound on; the melody is an extra memory channel.
• Group the sequence into chunks of three and repeat each chunk under your breath.
• Tap in the same physical rhythm as the playback - rhythm is memory.

Who it suits: Perfect for players who want a real challenge in a small package - commuters, students, and anyone who enjoys beating their own record more than beating other people.
