Think faster, not just turn faster. Cube Brain Trainer teaches you to solve the cube step by step — and trains the part of solving that happens in your head: recognizing cases, recalling algorithms, and deciding your next move. Your first goal: break the one-minute barrier. A guided path from zero to full CFOP - Start with the cross and first layer — no experience needed - Learn F2L, then OLL and PLL, one bite-sized case at a time - Choose your route: beginner-friendly 2-look, or the full 1-look sets - Full OLL (57) and PLL (21) case libraries, verified move by move Learn by doing, on a 3D cube - Every case comes with a memorable, verified solution - Watch the demo from any angle, pause it, turn the cube yourself - Recognition cues tell you what to look for — shape and position Practice and see yourself improve - Time attack mode with phase-by-phase stats (cross, F2L, OLL, PLL) - Spot which step slows you down, then jump straight to the lesson for it - Replay any solving move by move, and re-solve a single phase to drill it - Cases fade as your memory does — review them right before you forget - Streaks and progress tracking keep you coming back Honest about what it trains Your times in this app measure how fast you think — recognition and recall — not finger speed. That's the point: build the mental side here, then make your real cube faster with hands-on practice.
