Ball Box: Color Slide Puzzle

One swipe moves everything.

Ball Box is a small, calm sliding puzzle. Swipe in a direction and every ball on the board slides that way at once, until a wall, an edge or another ball stops it. You choose the direction — the board decides where things land.

Each ball has its own color box, and it only counts in that one. Getting every ball into a box is easy. Getting every ball into the RIGHT box is the puzzle.

WHAT MAKES IT HARD
• A ball that reaches its own box settles there and stops moving — but it is still in the way of everything else, so the order you solve in matters.
• Fix one ball and you have usually moved another one somewhere worse.
• Every few levels an ALL AT ONCE board arrives: nothing settles, and all the balls have to land on the same move.

EVERY BOARD HAS A BEST ANSWER
Levels are not hand-tuned guesses. Each board is solved completely before you see it, so the move count shown is the true shortest solution — not a number somebody picked. Three stars means you found the optimum, and it means it honestly.

The hint knows that solution, so it never guesses either. And undo is generous: ten to start, ten more for a short ad, and ten back every two hours — because a swipe moves everything and taking one back is part of playing, not a favour.

A CALM, RELAXING BRAIN GAME
No timers. No lives. No waiting to play. It is a logic puzzle you can put down mid-level and pick up a day later, and it works with no internet at all — offline on a plane, a train, or a basement.

Levels keep coming, and every one is checked by the solver before it is handed to you, so you will never be stuck on a board that cannot be finished.

MAKE IT YOURS
• 12 boards to unlock, from plain to marble to gilt
• 14 color sets
• A daily challenge with its own board every day
• A level map that keeps going

Colors were checked against red-green colour blindness simulation, because in this game the color IS the rule — the three ball colors stay distinguishable, and every board sits well clear of them in lightness.

Made for the bus, the queue, the ten minutes before sleep.

Recent changes:
The level map now runs as one continuous road instead of stopping dead every fourteen levels.

The game also tells you when a newer version is on Play, so fixes actually reach you.
