Simon — Memory Sequence

Simon is a free browser-based memory sequence game that tests your ability to watch and repeat increasingly longer color patterns. Each round, you watch the game play a sequence of colored lights, then click them back in the same order. It's the classic Simon Says game brought to your browser, requiring nothing but your attention and quick reflexes.

With every correct repetition, the sequence grows by one more color, ramping up the challenge steadily. What starts simple becomes a real memory and concentration test as the rounds progress. Since it runs entirely in your browser with no sign-up required, you can jump in and start playing instantly—your scores stay on your device.

This memory sequence game is perfect for quick mental breaks, training focus and recall, or just seeing how long a pattern you can remember. It's engaging enough to hold your attention but simple enough that anyone can pick it up and play immediately.
