SPECIAL TILES
- ROCK: Cannot be merged. Crack it with 3 nearby merges to shatter it!
- BOMB: Merge it to detonate a massive 3x3 explosion and clear the board.
- RAINBOW: A wild tile that merges with any number.
- FROZEN: Frozen solid - slide it twice to thaw the ice before it can merge.
A new special tile drops every 20 moves, so no two runs ever feel the same.
