Cube Jam Online

by crokocat · Puzzle

Cube Jam is a 3D color-clearing puzzle: a solid figure built from colored cubes, and one rule for taking it apart. Tap a cube and it disappears along with every same-colored cube connected to it, however big or small that group turns out to be. The rest of the shape settles inward to close the gap, and the goal is to strip the whole figure down to nothing before your moves run out.

The rule is simple, but reading it in three dimensions is not: a group is any cubes of the same color touching face-to-face, and it can wrap around a corner, run through the middle of the shape, or hide almost entirely out of sight on the far side. Spinning the figure before you commit to a move matters as much as picking the right color — the biggest group is rarely the one facing you when the level opens.

Cleared cubes don't just vanish. They fly off into a row of jars, one per color, so you can see at a glance how much of each color is left buried in the shape and how close you are to finishing it. Watching the jars fill up is half the satisfaction of a good clear.

Across 500 levels the shapes grow from simple tiles and cubes into spheres, octahedra, cuboctahedra, rhombic dodecahedra, spiky stars, drums and spires, each with its own move limit tuned to how it actually solves. Finish inside the limit for a level to count, match the shape's optimal solution for all three stars, and check back daily for a puzzle that's the same for every player that day.

Everything runs free in the browser on desktop, phone or tablet — no download, no sign-up. Your progress and stars are saved locally, so you can close the tab and pick up the campaign exactly where you left it.

Frequently asked questions

Is Cube Jam free to play?

Yes. Cube Jam is free on crokocat with no download and no sign-up — it runs entirely in your browser, on desktop, phone or tablet.

How do I clear a group?

Tap any cube. Every cube of the same color connected to it face-to-face is removed in that one move, no matter how the group is shaped or how much of it is hidden inside the figure.

What do the jars mean?

Each jar tracks one color. Every cube you clear flies into its matching jar, so you can see how much of that color is left in the shape without having to spin it around and count.

How does the star rating work?

Finishing right at the move limit earns one star, finishing with moves to spare earns two, and matching the level's optimal solution earns all three.

How many levels are there?

500 campaign levels, plus a new Daily Puzzle every day that's the same for all players.

Does it save my progress?

Yes, your level, stars and daily streak are stored in the browser, so you can close the tab and pick up where you left off.
