How much can you recall after the picture disappears? Zanzou is a visual memory game: watch colored shapes, letters or digits flash one by one, then answer a question using four choices. Recall what appeared, its order, color or position. CHOOSE YOUR CHALLENGE • Levels 1–100 are free and introduce harder combinations step by step. • Position asks you to remember where elements appeared on a nine-zone board. CHANGE THE RULES Later rounds can blur a shape, show grayscale, delay the question, mute sound, alternate display time or ask you to choose an incorrect answer. Read the round's rule before answering. Check the result screen to review the questions and what was shown. FREE PLAY AND Zanzou Plus The free version includes ads. Zanzou Plus is a one-time in-app purchase that includes: • No ads. • The Master+ course, levels 101–110. • Saved detailed answer history and review. • Insights under matching conditions over 7, 30 and 90 days. • Focused three-question practice. If you previously purchased Remove Ads, you receive every Zanzou Plus feature at no extra charge. The price is shown on the in-app purchase screen. Scores describe your performance in the game. The displayed “Memory Age” is an in-game indicator calculated from accuracy and reaction time, not a measure of your actual brain age or a medical assessment. No account is needed to play.
