How to Play

The rules

The computer lights up a sequence of colored pads, each playing its musical note.
After the sequence finishes, repeat it by clicking the pads in the exact same order.
Each correct round adds one more step to the sequence.
One wrong click ends the game — your score is the level you reached.

The 8 notes

Each pad plays a note of the C major scale: Do · Re · Mi · Fa · Sol · La · Si · Do'
Use both the color and the sound to memorise the sequence — the combination makes it much easier.

Difficulty

Easy — slow playback, plenty of time to watch.
Medium — normal speed, a good challenge.
Hard — fast playback, train your reflexes.

History of Simon

Memory Sequence is inspired by Simon, the electronic memory game invented by Ralph Baer and Howard Morrison and released by Milton Bradley in 1978. The game became one of the defining toys of its era, selling millions of units worldwide.

Simon itself was based on an Atari arcade game called "Touch Me" (1974). The iconic circular design with four large coloured buttons — red, blue, green, yellow — became instantly recognisable. Each button played a distinct musical tone when pressed.

Our version expands the original to 8 pads, each mapped to a note of the C major scale, adding a richer musical dimension to the memory challenge. The 3×3 grid layout is inspired by modern drum pads.

Tips & Fun Facts

Memory strategies

Chunk the sequence — group 3–4 notes mentally rather than remembering them one by one.
Sing along — humming the melody as the computer plays it locks the sequence into musical memory, which is more durable than visual memory.
On Easy, focus on spatial position (top-left, center-right…). On Hard, rely more on sound — you won't have time to think visually.
Start with Medium to calibrate your pace, then push to Hard once you can reliably reach level 10.

Did you know?

The world record for the original Simon game is over 31 steps — the theoretical maximum of the original device.
Research shows that musical patterns are remembered up to 3× better than purely visual ones.
The C major scale (Do Re Mi Fa Sol La Si) is the foundation of Western music — most people can hum it after just a few rounds.
