Classic pattern-memory game. The board plays a colour + tone sequence. Repeat it. Each correct round adds one more step. Your best round is saved in your browser.
How to Use
The board flashes a coloured tile with a tone. Repeat the pattern by clicking the same tile. Every correct round adds one more step to the sequence. Get one step wrong and the round ends. Your best round is saved in your browser.
Crypto-random selection picks each step from four pads (green, red, yellow, blue) with unique tones (220 Hz, 280 Hz, 330 Hz, 440 Hz). As the sequence grows, the playback speeds up. No server calls, no tracking of your patterns: everything runs locally.
Most people plateau around 8 to 12 steps. Trained memory users reach 20+. The classic Simon electronic game topped out at 31 steps. Challenge yourself against your own best round.
About This Tool
Memory Sequence is a classic Simon-style pattern memory game. The board flashes a colour and tone; you repeat the pattern by clicking the pads. Each correct round adds one step; a wrong click ends the round. Your best round is saved in your browser.
Four pads (green, red, yellow, blue) each have a unique tone (220 Hz, 280 Hz, 330 Hz, 440 Hz). Playback speed increases as the sequence grows, mimicking the 1978 Simon electronic game that topped out at 31 steps.
Random tools are most helpful when the rules are clear before the result is generated. Decide what the input means, whether duplicates are allowed, and whether the first result should be final. Clear rules make the result easier to trust and explain.
For casual choices, games, classroom activities, examples, and creative prompts, a browser-based tool is usually enough. For regulated contests, high-value selections, safety decisions, legal records, or professional advice, use a process designed for that responsibility.

Frequently Asked Questions
Simon is an electronic memory game from 1978 with four coloured buttons, each with a tone. The game plays a random sequence; the player repeats it. Each round adds one step. Our version is a faithful web adaptation with crypto-random sequences and the same four-colour layout.
Short-term pattern memory typically caps at 7 to 10 steps unchunked. With active chunking or melody-like cues, trained people reach 15 to 20+. A few elite memorisers hit 30+. The original Simon electronic game stopped at 31.
Mixed evidence. Pattern memory trains working memory on the specific task well. Transfer to general cognition is contested: most research finds the improvements are narrow. What is consistent is that practice feels good and reduces boredom: play for fun, not for IQ.
Yes. Tick the "Mute sounds" checkbox before or during a round. The pads still light visually.
Yes, locally in your browser. Nothing is sent to a server. Clearing site data or using the Reset button deletes it.
Yes. Tap the pads instead of clicking. The layout is fully responsive; the board shrinks to fit.
