Sort balls into tubes. Some tubes hold 5 orbs, some only 3. A 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.
