## What is GrainGlass?

Sort. Settle. Unwind.

GrainGlass is the sand-sorting puzzle for anyone who loves water sort, ball sort, and tube-sorting games — but wants to actually watch the sand move. Every pour is a real granular simulation: individual grains fall, pile up, and settle into place, not a flat color filling a glass. Pour colored sand between glass tubes until each one holds a single color, and feel the whole board go still and satisfying at the finish.

WHY GRAINGLASS FEELS DIFFERENT
- Real sand physics — grains fall, jitter, and settle with a visible shake-to-level finish, not a liquid animation reused from every other sort game.
- Apple Liquid Glass tubes and UI — a genuinely modern look built for the newest iPhones, not a dated flat-color skin.
- Sound designed for sand — pour, trickle, and settle audio built specifically for this game, not stock water-splash effects.
- One-tap controls — tap a tube to pick it up, tap again to pour. No tutorials required.

CALM ON THE SURFACE, SHARP UNDERNEATH
Early levels ease you in. Later ones test real planning — more tubes, more colors, tighter capacity, and pours that only work if you've thought two moves ahead. Undo freely, restart with no penalty, and use a hint if you're stuck. There's no timer and no one to lose to — just you, the grains, and a board that wants to be solved.

FEATURES
- Hundreds of hand-checked levels with a genuine rising difficulty curve — every level is solvable, no dead ends.
- Unlockable sand and tube themes — Sunset Dunes, Midnight Glass, and more, each with its own palette and feel.
- Auto-saved progress — pick up exactly where you left off, every time.
- Fully offline — play anywhere, no connection required.
- Play with sound on. This one's built for headphones.

WHO IT'S FOR
If you've burned through water sort, ball sort, or color sort puzzle games and want the same addictive one-mechanic loop with a satisfying new texture, GrainGlass is the next one to try. It's a calm, no-pressure puzzle for a commute, a waiting room, or unwinding before bed — pick it up for two minutes or two hours.

Pour. Sort. Watch it settle.
