Store description excerpt
Hueku is sudoku — but with colors. Instead of numbers 1 through 9, you place 9 hand-picked colors on the grid. Same rules you already know: every row, column, and 3x3 box must contain all 9 colors exactly once. New way to see it. WHY COLORS? Numbers train your logical brain. Colors train your visual brain. After a few puzzles, you stop thinking "what's missing" and start seeing it. It's calmer, faster, and feels nothing like the math homework version. 4 DIFFICULTIES - EASY: gentle introduction, 5 lives, around 40 colors pre-filled - MEDIUM: the daily-coffee level, 4 lives - HARD: for when easy feels like reading, 3 lives - EXPERT: sparse boards that take real concentration, 3 lives Every puzzle has exactly one solution. Generated locally on your device. No internet required. DESIGNED TO RESPECT YOUR TIME - No accounts. No login. No email. - No banner ads cluttering the screen. - Optional rewarded ads: only when YOU tap to restore a life or reveal a hint. - Or unlock Hueku Pro ($3.99 one-time) to remove ads forever. - No notifications begging you to come back. ACCESSIBILITY - Optional 1-9 number labels on top of each color, for color-vision accessibility. - Adaptive light and dark themes: switches automatically with iOS. - Full VoiceOver labels. - Adjustable haptic feedback. - Available in 15 languages. WHAT YOU TRACK - Personal best time per difficulty - Current streak and best streak - Score breakdown after each win - "New Best" celebration when you beat your record All stored locally on your device.
