Prism — Color Block Puzzle

A vibrant color-block puzzle in a Chrome popup. Place pieces, clear lines, chain combos, dodge obstacles. Fully offline.

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 ▸ FEATURES ✦ Two ways to clear: lines AND color clusters, with dual-clear bonuses ✦ Stone obstacles that can only be destroyed by line clears ✦ Combo multiplier up to ×5 ✦ Sound effects with toggle + volume controls ✦ Persistent high score across sessions ✦ Smooth animations, particles, screen-shake on big combos ✦ One-thumb gameplay — works on touchscreens ▸ PRIVACY (READ THIS) PRISM stores your high score and audio settings on your device only.
