Sudoku was just the warm-up. Unwind with Ripply, a relaxing logic puzzle inspired by Ripple Effect and Suguru. Fill every zone while respecting the distance rule between identical numbers. Why you’ll love Ripply: • Puzzles for every level: progress from Beginner to Extreme. • Clean, minimalist design: stay focused on each deduction. • Daily challenge: discover a different puzzle every day. • Notes mode: keep every possibility in sight. • Play at your own pace: no pressure, just satisfying logic. • Ad-free option: remove ads for an uninterrupted experience. How to play: • Zones: each area outlined by bold lines is a zone. A zone with N cells must contain every number from 1 to N exactly once. • Distance rule: when the same number appears in a row or column, at least that many cells must separate the identical numbers. For example, two 4s must have at least four cells between them. Use deduction to complete every zone and watch each answer unlock the next.
