Sequence Master Challenge

Sequence Master 3.0 is here! Master the Stroop test, train at chimpanzee flash speeds, challenge friends in split-screen duels and track your 5-axis cognitive profile.

Elevate your brainpower with Sequence Master — the comprehensive cognitive training and working memory app engineered to boost recall, focus, reflexes, and mental flexibility.

Featuring 8 scientifically grounded training modes, Sequence Master adapts to your skill level while presenting an elegant dark forest aesthetic that makes daily brain training a joy.

8 DIVERSE GAME MODES • STROOP ILLUSION [NEW IN 3.0]: Tap the ink color while suppressing the reading reflex. A gold-standard neuropsychological challenge of inhibitory control. • CHIMPANZEE MEMORY TEST & AYUMU FLASH [NEW IN 3.0]: Memorize numbers across the grid before they hide. Turn on Ayumu mode to test your photographic memory at 0.21-second speeds! • ADAPTIVE DUAL N-BACK [NEW IN 3.0]: Track spatial locations and audio tones simultaneously. The adaptive engine automatically raises N as your accuracy exceeds 80%. • COLORS: Watch the grid flash and reproduce the sequence with precision. • NUMBERS: Numbered tiles appear briefly across the grid. Recall and tap them in ascending order. • REVERSE: Exercise executive memory by repeating sequences backwards. • SPEED: Pure reaction time — strike flashing targets before the timer runs out. • CONSTANTS (π, e, φ, √2): Memorize the decimals of mathematical constants with an interactive reference library and mistake heatmap.
