## What is Sixteen Hole Calibration?

16-Hole Calibration is a quiet single-player logic puzzle built around an ancient sixteen-holed astrolabe. Slide energy gems across a compact 4x4 relic board, use blockers wisely, and place each gem into its matching target seat to restore the old alignment.

Every level is small, readable, and deliberate. The challenge is not speed, but order: which gem should move first, and which one must become the stopper for another?

Features:
- Swipe-based sliding puzzle controls
- 4x4 ancient calibration board
- Offline single-player play
- Level progression and local save data
- 1-3 star scoring based on move efficiency
- Music and sound settings
- Clean relic-inspired visual style
