Simon Says Game

What this tool does

Simon Says Game recreates the classic electronic memory game: each round adds one more step to a growing sequence of colored pads, watch it play, then repeat it by clicking the pads in the exact same order, with your current and best round tracked.

Simon is the classic electronic memory game: a sequence of colored pads lights up in order, you watch, then repeat it exactly, each successful round adds one more step, testing how long your short-term memory can keep up.

This version recreates that core loop with four colored pads: watch the growing sequence play, then click the pads back in the exact same order, one wrong pad ends the run, with your current and best round tracked.

How to use Simon Says Game

1. Click "Start game."
2. Watch the sequence of pads light up in order.
3. Click the pads back in the exact same order.
4. Each successful round adds one more step, keep going until you make a mistake.

Tips for better results

• Try grouping the sequence into small chunks mentally (like remembering a phone number in groups) rather than one long unbroken sequence, this is a well-known memory technique that helps with longer Simon sequences.
• The sequence always plays from the very first step each round, even as it gets longer, so you’re re-watching and re-confirming the earlier steps every time, use that repetition to reinforce your memory.
• A single wrong pad ends the run immediately, there’s no partial credit, take a moment to be confident before clicking each pad rather than rushing.
• Your best round persists across attempts within the session, giving you a clear target to beat on your next try.

Common use cases

• A classic memory-training game for players of any age.
• Practicing and measuring short-term sequential memory capacity.
• A quick, satisfying game to play during a short break.
• A nostalgic recreation of the original electronic Simon toy.

Common mistakes to avoid

• Trying to memorize the whole sequence as one long unbroken string rather than chunking it into smaller groups, chunking is a well-established memory technique that generally helps with longer sequences.
• Rushing through your input without being confident of the next pad, since a single wrong click ends the run immediately with no partial credit, a brief pause before clicking is usually worth it.
• Expecting partial progress to carry over after a mistake, a wrong pad ends that run completely, you start a fresh sequence from round one on your next attempt.
