What Cubers Say
Frequently Asked Questions
Do I need to create an account?+
No! Cube-Kala is completely login-free. No accounts, no passwords, no tracking. Just open the site and start solving. Your preferences are stored locally in your browser.
How does the Two-Phase Solver work?+
It uses the Kociemba algorithm, which splits the solve into two phases: first reducing the cube to a simpler subgroup, then solving that subgroup optimally. It runs entirely in browser Web Workers so the UI stays smooth.
What is a Mirror Cube?+
A Mirror Cube (also called a Mirror Blocks or Bump Cube) is a 3×3 puzzle where pieces are different sizes instead of different colors. When scrambled, it becomes an irregular shape. Our 3D builder lets you explore this in WebGL.
Is Cube-Kala free forever?+
Yes, 100%. Cube-Kala is and always will be free. No premium tiers, no paywalls, no ads. It's built by the community, for the community.
