Description by Mostafa Ayman Written by the developer, not by AppBrain. Click to read.
9u9uCrest is a captivating logic puzzle game that challenges your spatial reasoning and pattern recognition skills. Rotate concentric rings filled with colorful geometric symbols to match hidden target rules.

HOW TO PLAY

Each level presents a multi-layered circular crest divided into sectors. Tap a ring to select it, then rotate it clockwise or counterclockwise. Every rotation counts as one move. Your goal is to rearrange the symbols so they satisfy the rule shown at the top of the screen.

Press "Confirm" to check your solution. Mismatched sectors are highlighted so you can learn from your mistakes and try again.

FEATURES

- Intuitive ring rotation controls with smooth animations
- Progressive difficulty with 2 to 4 concentric rings
- Multiple rule types including symbol grouping, color placement, adjacency constraints, and rainbow ordering
- Over 50 levels with hand-designed teaching puzzles
- Endless challenge mode with randomly generated puzzles
- Track your high scores and compete against your own records
- Minimalist dark theme designed for focused gameplay

RULES AND SCORING

Each puzzle has a unique target rule. Complete the puzzle within the move limit to advance. Use fewer moves for a better score. New rule types are introduced gradually through the teaching levels, making the game accessible to newcomers while remaining challenging for puzzle veterans.

WHY YOU'LL LOVE IT

ShiftCrest offers a perfect mental workout for commutes, breaks, or quiet evenings. Each puzzle is uniquely generated, so no two games play the same. The satisfaction of finding the perfect rotation sequence that solves a complex puzzle keeps you coming back for more.
