About Simon
This is a memory game built around four colored panels that light up and play tones. The game shows you a sequence, and you repeat it by tapping the colors in the same order. Each round it adds one more step, so the sequence grows longer and longer until you slip.
It comes from the late 1970s, when its distinctive light-and-sound toy became an arcade-era icon. The design is beautifully simple and quietly brutal: it starts insultingly easy, then a few rounds later your short-term memory is stretched to its limit and your fingers are tapping on faith alone.
You can play free in your browser with no download. There is nothing to learn beyond watch and repeat, which makes it instantly approachable for anyone. Beating your best streak is the whole draw, and it is the kind of game that pulls you into just one more try every time.
Controls
You play by watching, then tapping. The game flashes a sequence of colored panels with matching tones. When it finishes, you repeat the sequence by tapping the same colors in the same order.
The rhythm of a round is always the same:
- Watch and listen as the game plays the sequence. Each color has its own tone, so the sounds give you a second way to remember the order alongside the lights.
- Repeat the order by tapping the colors back exactly as they appeared. Get the whole sequence right and the game adds one more step for the next round.
A single wrong tap ends the run, so the game is a test of how long a sequence you can hold.
Each round makes the sequence longer, and the difficulty climbs across eight levels as the pace quickens.
Tips
- Use the sounds, not just the lights. Each color plays a distinct tone, so humming or listening to the melody gives you a second memory track that is often easier to recall than the colors alone.
- Group the sequence into chunks. Remembering 'red-red-blue' then 'green-yellow' as two small groups is far easier than holding five separate colors, the same trick people use for phone numbers.
- Say the colors to yourself. Quietly naming each color as it flashes turns the sequence into words, which are easier to rehearse and repeat than a string of silent lights.
- Stay relaxed and focused. Tension makes you rush and misremember, so keeping calm as the sequence grows helps you recall it cleanly instead of panicking near the end.
- Don't tap faster than you can think. There is no time pressure while you repeat, so tapping at a steady, deliberate pace prevents the slips that come from racing ahead of your memory.
- Watch the whole sequence before moving. Trying to tap along as it plays leads to mistakes, so wait for the full sequence to finish, then repeat it from the start.
Frequently asked questions
Is the game free to play?
Yes. You can play as many rounds as you want with no download and no account.
How do you play?
The game shows you a growing sequence of colored lights and tones. After it finishes, you repeat the sequence by tapping the colors in the same order. Each round adds one more step.
How do you win?
There is no final win. The goal is to repeat the longest sequence you can and beat your own best streak, since the game keeps adding steps until you make a mistake.
Why is it so hard after a while?
Each round adds another color to remember, and human short-term memory tops out at only a handful of items, so long sequences push right against that limit. Chunking and using the tones helps you go further.
Can I play on my phone?
Yes. It runs in any modern mobile browser with tap controls, so it works well on phones and tablets.
How do I get better?
Lean on the tones as much as the lights, break the sequence into small chunks, and name the colors to yourself as they flash. Staying calm and tapping steadily keeps you from slipping near the end.
