About this game

A falling-sand puzzle set on an alchemist's bench.

Pour pieces of alchemical sand into a glass vessel. On landing they crumble into thousands of grains that flow, slide and settle. Build a line of one colour from wall to wall and it dissolves. The sand keeps rising — how long you last is up to you.

AN HONEST ENDLESS GAME
One pure rule, no gimmick levels, no forced progression. Every line you dissolve is a line you built yourself.

FIVE WAYS TO PLAY
• ENDLESS — the pure run, played for the score.
• SQUEEZE — the glass narrows at every drop. Resist as long as you can.
• DREGS — a crust of stone lies on the floor. Break all of it: the only mode you can win.
• ART — no score and no end. Pour sand with a finger, press it in where you want it, then seal the work into a wax-stamped vial and keep it on your shelf.
• DISSOLVE — take a work back off the shelf and play it. It is dealt into the glass framed in stone, and every line you close eats into it.

RARE MATERIALS
A hot piece freezes into glass that counts for any colour. Salt melts and takes what it touches. Stone stays until a line shatters against it. Water levels into a floor, then dries away. The transmuter recolours the sand around it.

TWO TOOLS IN ART
The needle pushes grains aside and the column above drops into the gap: it leaves a furrow with a bank beside it, and nothing travels more than a cell, so two bands of sand stay two bands. Draw it down through the boundary between them and the colour above pours into the notch — a row of notches is how a figure is drawn. The injector adds: press for a disc under your finger, hold still and it grows, drag and it draws a line. Press one colour inside another and the first is left as a ring around it. Nothing is ever erased.

A BENCH FULL OF CHOICES
• Three Ways of the alchemist — Fire, Salt and Mercury — each a full palette of sands, unlocked with the Essence your lines pay.
• Six themes dress the room, three lit for night and three for day; four finishes tint the glass.
• Grain size from chunky gems to the finest powder: the same game at three resolutions.
• A record for every run you can lose, and a shelf that keeps your sealed works — 24 of them, with room for more to buy.

QUIET BY DESIGN
A dark, elegant apothecary's atmosphere — engraved stone, embers and glass. Light on ads: optional reward videos, one full-screen ad between two runs, and never anything in the middle of one.

In English, Italiano, Español, Français, Deutsch and Português.
