About this game
Memory Néon is a memory game in the Simon tradition, set in an amethyst sanctuary. On the altar stand four crystals of different shapes: a spike, a faceted sphere, a cube and an octahedron. Each has its own colour — ice, rose, jade, sun — and sings its own note: C, E, G and a high C, the four notes of a C major chord, so any sequence stays consonant. At the start of each round the crystals light up one by one, singing. A row of gems on the altar shows how many notes the round holds without ever revealing them: a lavender gem for each note the game sang, a cyan gem for each note you have played back. Then it is your turn: repeat the tune in the right order. Get it right and the next round replays the same tune with one more note. The sequence is drawn at random at the start of each game and then only extended: round 5 always begins with round 4. The pace quickens: a crystal stays lit for 520 milliseconds in the first round, then 12 less each round down to a floor of 230; the pause between two notes goes from 260 to 110 milliseconds. The screen reads “Round x/50”: 50 rounds is the maximum, and clearing it earns a “PERFECT”. Your score is the number of rounds fully reproduced. Every 10 rounds, an amethyst column in the backdrop lights up. At the first slip the run ends: the crystal you should have touched sings in its turn, then the end panel replays your tune. The four crystals are told apart on four independent channels — colour, shape, position and note — so the game stays playable with colour blindness. On mobile, touch the crystal you want; on a computer, click it or use the keys 1 to 4, or the arrow keys. Memory Néon is free in your browser, nothing to install.

How to play
Listen to the tune sung by four crystals, then play it back in order: it grows by one note every round, up to a maximum of 50 rounds.
Game rules
- Four crystals of different shapes (spike, sphere, cube, octahedron) each have their own colour and note: C, E, G and a high C.
- At the start of a round the crystals light up one by one, singing. The row of gems on the altar shows how many notes the round holds, without revealing them.
- Then play back the same tune, in the right order, by touching the crystals. While the game is singing, your presses are ignored.
- If you succeed, the next round replays the same tune with one more note: you play the whole run again from the start.
- The pace quickens: a crystal stays lit for 520 milliseconds in the first round, then 12 less per round down to 230; the pause between two notes goes from 260 to 110 milliseconds.
- Your score is the number of rounds fully reproduced. The screen reads “Round x/50”: 50 is the maximum.

How a run ends
At the first slip the run ends: the crystal you should have touched sings in its turn, then the end panel replays your tune. Your score is the number of rounds fully reproduced. If you clear all 50 rounds, the game shows “PERFECT” with the maximum score.
Tips & strategy
Say it out loud
Recite the sequence in your head — “spike, cube, cube, sphere” — while it lights up. Turning the flashes into a little rhythmic phrase helps a lot to hold the exact order.
Hold on to the tune
Each crystal sings its own note, so the sequence is a little tune, always consonant because the four notes make a C major chord. Many players remember the tune better than the positions of the colours.
Follow the staff
The row of gems shows how many notes are waiting and where you are: lavender for the notes the game sang, cyan for the ones you have played back. It never shows the tune itself.
Wait for the sequence to end
Your presses are ignored while the crystals sing, so there is no point rushing. The game speeds up, but it puts no time limit on your answer.
Did you know?
Memory Néon takes the principle of Simon, the electronic game launched by Milton Bradley in 1978. With its four big coloured buttons that each played a note, it was one of the first mass-market electronic toys.
The idea of repeating sequences was inspired by an Atari arcade cabinet called Touch Me. Simon tied a colour and a sound to every button; Memory Néon adds a distinct shape and position so everyone can read it, colour-blind players included.
The four notes — C, E, G, high C — make a C major chord: whatever sequence is drawn, the tune stays pleasant to the ear.
Frequently asked questions
- Is Memory Néon free to play?
- Yes. Memory Néon is completely free and runs straight in your browser — no download, no install, no paywall.
- How do you play Memory Néon?
- Hit “Play” to start Memory Néon. It runs on keyboard on desktop and on touch controls on phones and tablets — no controller needed.
- Do I need an account to play?
- No — you can play right away as a guest, and your best score is kept on this device. A free account (by email link, no password) syncs your high scores, puts you on the leaderboards and unlocks trophies.
- Does Memory Néon work on mobile?
- Yes. The game is responsive and fully playable with your fingers on phones and tablets, just like on desktop, with no app to install.
- Do I have to replay the whole sequence every round?
- Yes: with each success only one note is added at the end, but you must reproduce the whole tune from the start. The sequence is drawn once at the start of the game and then only extended.
- How can I play if I have trouble telling colours apart?
- Each crystal is set apart on four channels at once: its colour, but also its shape (spike, sphere, cube, octahedron), its position on screen and its musical note. You can follow the sequence by shape, place or sound alone.
- How many rounds does it take to finish the game?
- The sequence is at most 50 notes long: clearing all 50 rounds earns a “PERFECT”. A trophy already rewards 30 rounds.
