Color Grid: Block Puzzle

Expanded Core Game Rules
1. Grid Sizes & Color Types
Early stages use compact 3×3 grids with 2 hues (red + orange). Starting from Level 6, puzzles expand to 4×4 grids with 3 distinct colors: green, orange, red. Later special levels (like Level 8) introduce star decorative tiles as unique target markers inside the template grid.
2. Drag & Fill Mechanic
Color orbs sit along the right and bottom edges of the play area. Simply drag each orb onto any empty white tile of the lower grid to paint the cell. No move limits, you can re-drag tiles to swap colors anytime if you misplace a shade.
3. Clear Completion Trigger
Once your bottom grid matches the top reference template pixel-for-pixel, the "COMPLETE!" text pops up on screen, unlocking the textured "NEXT" button to advance to the next puzzle chapter.
4. Level Select Library
The main Codex menu holds a 6-row × 5-column lock grid. Every solved puzzle unlocks one locked padlock, letting you browse all completed color challenges via page navigation arrows.
