Glow Sort: Water Tube Puzzle

Glow Sort is a relaxing color puzzle about pouring liquid between
glass tubes until every tube holds a single color.

Tap one tube, then tap another to pour. Water only flows onto matching
colors. Sort every tube, clear the board, move on. That is the whole rule —
you will understand this puzzle in ten seconds and still be sorting an hour
later.

🧪 EVERY LEVEL IS SOLVABLE
Each puzzle is checked by a solver before you ever see it. No impossible
boards, no dead ends you could not have avoided. If you are stuck, a solution
exists — that is a promise most sort games cannot make.

💧 ENDLESS PUZZLES
Levels never run out. The water sort puzzles keep generating as you play, and
they keep getting harder: more colors, more tubes, tighter space to move
liquid around.

🌅 TWELVE WORLDS
The background changes color every ten levels — Lagoon, Indigo, Teal,
Amethyst, Midnight, Berry and more. You always know how far you have come.

📅 DAILY CHALLENGE
One puzzle a day, the same one for every player. Come back tomorrow for a new
liquid sort challenge and keep your streak alive.

costs money — this puzzle game has no in-app purchases at all.

👁 EASY ON THE EYES
Our color palette is designed so every liquid is told apart by brightness, not
just by hue. If you are color blind, this sort puzzle was made for you too.

☕ NO PRESSURE
No timer. No lives. No energy to wait for. Pour water, sort colors, undo a
move, think again. A calm puzzle for a bus ride or a coffee break.

🔌 PLAYS OFFLINE
No internet needed. Sort tubes on a plane, in the subway, anywhere.

HELPFUL TOOLS
• Undo — three free every level
• Hint — shows the next move toward the solution
• Extra tube — one more glass when the board gets tight

WHY PLAYERS LIKE WATER SORT PUZZLES
Sorting colored liquid is quietly satisfying. Every pour is a small decision,
every finished tube is a small reward, and the color puzzle asks just enough of
your brain to be interesting without ever being stressful.

If you enjoy ball sort, tube sort, liquid sort or any color sorting brain
puzzle, Glow Sort will feel familiar in the first minute and get properly
challenging by the tenth.
