Cube Sweeper is part of Steam Next Fest, October 19 to 26, 2026.
The free demo stays open through the fest. It is available now, so there is no need to wait for the fest to start. Every board in the demo is generated and certified exactly like the full game's.
Cube Sweeper is Minesweeper played on the surface of a 3D solid: you orbit the board and read the numbers around corners. Every board is certified solvable by pure logic, every mine and every hidden gem. No guessing.
During the fest I will read the community hub every day. Questions and suggestions are welcome.
The full game launches in November 2026. Wishlist Cube Sweeper to be notified the day it releases.
