ShapeFall

Match colors. Chain combos. Survive the panic. A mobile-first puzzle game on tglgames.com.

How it plays

Colored shapes fall continuously into a 7×12 grid. Slide them left/right and drop them where you want. When 3 or more matching shapes (same color or same type, depending on the mode) connect, they clear and award points. Gravity collapses pieces into the empty space, often triggering a chain reaction — and bigger chains are worth a lot more.

Combos compound. Clear again before the combo timer expires and the score multiplier climbs (×1 → ×2 → ×3 → ×5+). Let the stack creep toward the top and the panic meter kicks in: drop speed climbs and the stage shakes. Survive long enough for the next perfect chain to buy you breathing room.

Modes

• Endless — survive + score. Difficulty climbs over time (faster drops, more colors, special blocks).
• Timed — score as much as possible in 90 seconds.
• Challenge — goal-based runs (e.g. clear 50 red shapes, survive 60s with only 3 colors).

Anti-cheat

Every run is replay-validated server-side using the same Mulberry32 PRNG the client uses. The server re-spawns shapes from the seed, replays your moves deterministically, and scores the run itself. Fabricated submissions don't post.
