Sort glowing energy cores by colour in armoured tubes and stabilise the reactor. Time attack and hard mode!
About the game
Ball Sort moves the familiar sorting puzzle inside a sci-fi reactor. Armoured glass tubes with steel clamps stand in front of a dark control panel, holding mixed glowing energy cores in cyan, orange, crimson, toxic green and violet. Tap a tube and its top core lifts into the air, tap another tube and it flies over with a light trail and drops in with an impact spark. A core can only land in an empty tube or on top of the same colour. When a tube holds four matching cores a steel cap slams down to seal it and an energy wave ripples out, and sealing tubes on consecutive moves builds an overload multiplier. In Classic, levels come in sets of five, new core types join the mix and your progress is saved. In Time Attack you start with ninety seconds and every solve adds fifteen more. Hard mode hides the lower cores, removes undo and sets a move limit. Your best results are ranked in the menu next to clearly labelled BOT rivals. Play free in your browser, no download needed.
How to play
- Pick Classic, Time Attack or Hard in the menu.
- Tap a tube; its top core lifts up.
- Tap another tube; the core lands in an empty tube or on the same colour.
- Four matching cores seal a tube; consecutive seals build an overload multiplier.
- Seal every tube to clear the level; running out of time or moves ends the run.

FAQ
Can every level be solved?
Yes, levels are generated by scrambling a solved state backwards, so each one has a guaranteed solution.
What is the difference between the modes?
Classic goes level by level with saved progress, Time Attack races the clock, and Hard adds hidden cores and a move limit with no undo.
Can I play on my phone?
Yes, you just tap the tubes; no download needed.
