Glupo Puzzle: Water Sort

Tap a tube to lift the liquid from the top. Tap a second tube to pour it in. Water only pours onto the same colour, or into an empty tube. Gather every colour into its own tube to clear the level.

That is the entire rule set — no tutorial to sit through, no menus to learn. Easy to understand in seconds, and a great deal harder to master than it first looks.

200 LEVELS, EVERY ONE SOLVABLE
A sorting puzzle is only fair if a solution really exists. Shuffle tubes at random and some boards come out impossible, which is how players end up stuck on a level that was never finishable. Every level here was checked by a solver before it shipped — the game knows the shortest solution to all 200 boards, because it worked each one out and replayed the moves to the finish. If you are stuck, the answer is there.

A CURVE THAT GENUINELY CLIMBS
— Tubes get deeper, from two units of liquid up to five
— More colours join, up to seven at once
— Free space shrinks, so there is less room to manoeuvre
By the later boards there is almost nowhere to park a colour you poured by mistake. Space becomes the real puzzle, not the colours.

THREE HELPERS
— Undo: step back through your moves one at a time
— Hint: reveals a pour that keeps a solution alive
— Shuffle: rearranges the board into a fresh layout that is still solvable
You begin with three of each, nothing is locked behind them, and you are never forced to use them.

EARN YOUR STARS
Three stars for finishing in the shortest possible number of moves, two for a tidy solve, one for getting there in the end. Your lowest move count is saved per level, so there is always a cleaner solve to chase. Three stars on a late board means you found the exact solution the solver did.
