Blue spheres
By Klemen Z
Blue spheres is a small browser puzzle game by Klemen Z in which you guide shiny blue orbs through mazes built from stone walls and grass, working around the obstacles in each layout. The view is a flat top-down rectangle surrounded by water, so the whole maze is visible at once. It runs free in your browser on desktop, with no download or sign-up.

How to Play Blue spheres
Each stage is a single walled rectangle sitting in the water. Inside it, stone blocks divide the grass into corridors, dead ends and narrow gaps, and one or more blue spheres sit somewhere in the maze. You use the movement keys to work the spheres through those gaps and past the stone barriers.
Layouts change as you go. The frames show a stage with two wide chambers joined by a single opening, then a tighter version where the middle of the field is cut into thin vertical channels, so the same movement has to be threaded through much narrower routes. Letter markers (P, R and M) appear along the top edge above the maze, and the game also uses M, R and P keys alongside the movement keys.
Because the whole board is on screen, the puzzle is about reading the walls before you move rather than reacting quickly.
Tips
- Trace the corridor with your eyes first — the stone blocks often leave only one gap between chambers, and that gap is easy to miss.
- In the tighter layouts the field narrows into thin vertical channels; line a sphere up with the channel entrance before committing to a long move.
- Watch both spheres when two are on the board, not just the one you are pushing.
- Keep the whole rectangle in view — nothing scrolls, so every wall you need to plan around is already on screen.
