Drills ── one per step.

Each drill page shows a scrambled case, lets you solve it cube-in-hand, then reveals the optimal solutions. Mark correct / needs-work; the picker leans toward the cases you keep missing. All marks stay in your browser — no accounts.

• SB Live

  Second Block — pairs drill ──>

  Solve drill for both SB pairs (BR + DBR back, FR + DFR front). Trouble-weighted picks, woodpecker cycles, per-case marks in localStorage.

• CMLL Planned

  CMLL recognition + solve

  Show-then-reveal recognition mode plus a solve mode, fed from the curated CMLL alg sheet.

• EO Planned

  EO recognition

  Show an LSE state, name the EO case, reveal. Recognition-first because EO is a small case set.

• 4c Planned

  4c solve drill

  Last four corners under strict ⟨M2, U2⟩.
