Astro Jam: Block Sort Puzzle

Astro Jam is a color block sort puzzle set among the stars - slide the blocks, clear the board, escape the jam.

Every colored block has a matching door waiting on the edge. Drag a block and it slides until a wall or another block stops it, then line it up flush inside its door to clear it. This sliding block sort puzzle is easy to learn in ten seconds but quickly becomes a real brain teaser and a satisfying color sort challenge.

WHY YOU WILL LOVE IT
- One simple rule: match every block to the door of its own color
- A sliding puzzle that starts gentle and gets genuinely hard
- Every level is built backwards from a solved state, so it is always solvable
- Colorblind friendly - each color carries its own symbol too
- A relaxing brain teaser to play offline in short bursts or long sessions
- Global leaderboards for every mode, so a good board is worth something
- Free with no in app purchases - nothing is locked behind a paywall

GAME MODES

- Endless: fresh puzzle boards at your chosen difficulty, never the same twice
- Daily Challenge: one block sort puzzle a day, the same board for everyone, with a streak to protect
