Prism — Color Block Puzzle

About

Cure new-tab boredom in 30 seconds.

PRISM turns every new tab into a satisfying color-block puzzle. Drag pieces onto an 8×8 grid, clear full rows and columns, pop clusters of matching colors, and chain combos for multipliers up to ×5. Pick it up for a quick break. Put it down whenever. No timer, no pressure.

▸ HOW IT PLAYS

- Drag any of 3 pieces from the tray onto the 8×8 grid
- Fill a row or column → it clears (line clear)
- Connect 4+ same-colored blocks adjacent to existing ones → they pop (color match)
- Trigger both in the same move → bonus multiplier
- Chain clears across consecutive turns → combo multiplier up to ×5
- Game ends when no piece fits anywhere on the board

▸ 5 DIFFICULTY LEVELS

Climb thresholds to unlock harder shapes, more colors, bigger match requirements, and faster obstacle spawns. Each level adds a real twist:

- LV1 — 3 colors, easy shapes (warm-up)
- LV2 — tetrominoes unlock + stone obstacles begin spawning
- LV3 — 4th color enters, obstacles spawn faster
- LV4 — all 5 colors, S/Z + plus shapes, match threshold rises
- LV5 — expert mode with weighted hard shapes
