About Sort Flask

Ball-and-water sort in a midnight alchemist's lab. Pour the top color of one glowing flask into another — onto an empty flask, or onto a matching top color with room — until every flask holds a single solid color. Sort the whole rack to brew a deeper, harder layout; the run never ends on a sort. Every generated rack is proven solvable by a real solver, and you always have undo + reset, so you never hit a dead end. The only way out is running your move budget dry. Bank essence to buy permanent bench upgrades.

How to play

Tap (or click) a flask to pick it up, then tap another flask to pour its top color in. You can only pour onto an empty flask, or onto a flask whose top color matches — the whole top run flows across. Make every flask one solid color to sort the rack and descend one batch deeper, forever. Desktop: number keys 1-9 select/pour, Arrow/A-D move a cursor, Space or Enter acts, H hints, U undoes, R resets. Use Hint, Undo, Extract and Reset whenever a rack gets tangled. Spend essence at the Essence Bench on permanent tools.
