Zanzou — Working Memory

Zanzou is a minimal brain trainer for working memory. Colored shapes, characters, and digits flash briefly, then vanish. Four choices test what you saw. As levels climb, stimuli multiply, distractors appear, and questions sharpen. You fight with the residue. 〔Modes〕 • Levels 1–100 — graduated difficulty. Question types unlock by phase. • Daily Challenge — five seeded questions per day, with a weekday twist. • Endless — runs until three mistakes. Difficulty adapts. • Position — track which of 9 cells held each stimulus. 〔v2 additions〕 • Six modifiers — Blurred, Mute, Delayed, Silent, Strobe, and Reverse reshape later rounds. All are free. • Combo system — chain correct answers from WARM through FOCUSED to ZONE. Up to 2× score. • Adaptive difficulty — Endless and Position respond to your form. • Daily Twist — different constraints Monday through Saturday. Tomorrow's twist previewed today. • Streak flame — quiet count of consecutive days played. • Result share image — score and stimulus row, ready for social. • Immediate-correct highlight — the right answer outlines green the moment you tap. • In-review stimulus replay — each question's stimulus row in the recap. 〔20 question types〕 Nth stimulus / Nth color / Nth position / Was present / First or last / Reverse order / Color-shape separation / Count / Same or different / Stroop conflict / Missing item / Adjacency / Position / Combined / Digit sum / Most frequent / Excluded / Reversal / False memory trap / Attribute count. 〔Memory Age〕 Computed from accuracy and speed.
