Orb Tubes: Ball Sort Puzzle

Orb Tubes is a ball sort puzzle. Colored balls start mixed across a row of glass
tubes, and you pour them from tube to tube until every color sits alone. You may
pour a ball only onto a ball of the same color, or into empty space. That is the
whole rule, and it takes ten seconds to learn.

The hundredth level will still take you a while.

🔵 THE TUBES ARE NOT ALL THE SAME SIZE
This is what makes Orb Tubes different from other ball sort games. Some tubes
hold five balls, some four, some only three. A five is a valve: room to park an orb
you cannot place yet. A three is a trap, because it can never hold a
complete color, so everything you drop there has to come back out. Each tube is
as tall as the number of balls it takes, so you see which is which before you
pour.

🎨 COLORS YOU CAN ACTUALLY TELL APART
The most common complaint in this genre is that two colors look the same. This
palette was not picked by eye — it was generated and measured, including a
simulation of color blindness, and the closest pair of orbs in the set stays far
enough apart to be safe. Twelve distinct colors, and the first ones you meet are the
furthest apart.

✅ EVERY LEVEL IS CHECKED BEFORE YOU SEE IT
Every puzzle is solved by the generator before it reaches your screen. A solution
always exists. No dead ends, no impossible boards, no level nobody tested.

♾ THE LEVELS NEVER RUN OUT
Puzzles are generated as you play and they grow: three colors at the start,
twelve later, with taller tubes and tighter space. No last level, no waiting.

🌌 TWELVE CHAPTERS
The puzzle changes color every ten levels — progress you see, not a number.

📅 DAILY CHALLENGE
One puzzle a day, the same one for every player in the world. Solve it and
keep your streak alive.

🛠 TOOLS WHEN YOU ARE STUCK
Undo any pour, as often as you like. A hint shows a move that leads to a real
solution, not a guess. Add one extra tube per level when a
puzzle has you cornered.

🎁 UNLOCK WITH ADS, NOT MONEY
Ball sets, tube shapes and backgrounds unlock for three short ads each. Nothing
costs money, and you always see how close you are.

☕ NO TIMER, NO LIVES, NO ENERGY
Take an hour on one puzzle if you want. A calm color sorting puzzle for a
commute, a queue or a coffee break.

🔌 PLAYS OFFLINE
No internet, no account, no sign-in. Sort balls anywhere.

💯 NO IN-APP PURCHASES
None at all. There is nothing in this sort puzzle that can be bought.

WHY BALL SORT PUZZLES WORK
A sorting puzzle shows everything at once. Nothing is hidden, nothing random,
and the answer is always on screen. Every pour is a small
decision you see the result of immediately, and the moment a tube fills with one
clean color is worth more than it should be.

If you like water sort, color sort, ball sorting games, hoop stacks or any puzzle
where you tidy something into place, Orb Tubes will feel familiar in the
first minute and get properly hard around level forty, when the small tubes
arrive.

Pour a ball. Sort the tubes. Sort them all.
