Mobile: Tap the colored buttons to repeat the sequence. Each is sized for confident finger presses.
Watch colored squares flash in sequence then repeat the order. Each round adds one more color. How far can your memory take you? Great for improving concentration.
Watch the sequence then click colors in the same order. Each round adds one step. One mistake ends the game!
Simon Says is a faithful digital recreation of the legendary electronic memory game that has challenged and delighted players since 1978. The game presents four colored buttons that light up in a sequence — your task is to watch the sequence, memorize it, and then repeat it exactly by clicking the buttons in the same order. Each successful round extends the sequence by one additional step, creating an exponentially growing challenge for your working memory. What starts as a trivial task (remembering one color) becomes genuinely difficult around step 7-8, and pushing past step 12 requires either exceptional natural memory or learned mnemonic techniques.
Simon was created by Ralph Baer (the 'Father of Video Games') and Howard Morrison, and released by Milton Bradley in 1978. The game was directly inspired by a 1970s Atari arcade game called 'Touch Me' that used the same sequential memory concept but failed commercially due to harsh buzzing sounds. Baer and Morrison reimagined the concept with pleasant musical tones — each button produces a distinct note — creating an experience that was as much musical as memorial. Simon became one of the best-selling toys of the late 1970s and early 1980s, winning numerous toy industry awards. The game's influence extends into popular culture: references to Simon appear in TV shows, movies, and other games. The concept has also been adopted by cognitive psychology researchers as a standardized measure of sequential memory capacity.
How to Play: Watch as colored buttons light up in a sequence. After the sequence plays, repeat it by clicking the buttons in the exact same order. Each round adds one new step to the end of the sequence. A wrong click at any point ends the game. Visual Feedback: Buttons light up brightly when activated (both during the sequence playback and when you click them), providing clear visual confirmation. Starting: Click the 'Start' button to begin. The first round shows just one button. Score: Your score equals the longest sequence you successfully reproduced. Mobile: Tap the colored buttons. They're sized for comfortable finger targeting.
Verbal Encoding: Say the colors aloud (or in your head) as the sequence plays: 'Red, Blue, Green, Yellow, Red, Red.' Verbal rehearsal engages your phonological loop — a dedicated short-term memory subsystem — which effectively doubles your memory capacity compared to visual-only memorization. Chunking: Group the sequence into chunks of 3-4: instead of remembering 12 individual colors, remember 3 groups of 4. Humans can hold 7±2 chunks in working memory, so grouping dramatically extends your maximum sequence length. Spatial Mapping: Associate colors with directions (Red=Up, Blue=Right, etc.). Remembering a direction pattern can be easier than remembering colors. Pattern Detection: Look for repeated sub-patterns within the sequence. If 'Red-Blue' appears twice, you only need to remember it once plus 'it repeats here.' Practice Consistently: Sequential memory is highly trainable. Most people can increase their maximum sequence by 3-5 items within two weeks of daily practice.
Sequential memory — the ability to remember ordered sequences of items — is one of the most important cognitive capabilities for learning and daily function. It's what allows us to follow multi-step instructions, remember phone numbers, execute recipes, and learn new procedures. Cognitive science research has established that sequential memory capacity predicts academic success more accurately than many other cognitive measures. A 2017 study in the Journal of Cognitive Enhancement found that participants who trained with Simon-like sequential memory games for 15 minutes daily showed significant improvements in reading comprehension and mathematical problem-solving — abilities that rely heavily on processing sequential information. Our game provides exactly this type of training in an engaging, motivating format.
Simon Says is built around an ever-growing array of colors. Each round I append a random color, then play back the whole sequence with visual (and timed) highlights. Then I capture your clicks and compare them index-by-index — one wrong click ends the run. The satisfying part was syncing the button 'flash' animation with the sequence playback timing. It's a small script, but getting the timing to feel natural rather than robotic took several passes.
