Practise one part of the solve
Drills
Every drill isolates one part of the solve, so a minute of practice gives you far more useful repetitions than full solves do. Scrambles are random-state: the part you drill is solved, everything else is truly random. With a smart cube the drill judges itself and moves straight on to the next one.
Build the cross. Pick how many moves its optimal solution has; after each attempt you see that solution, to step through on a cube.

Connect a smart cube: it sets each drill up with you move by move, starts on your first turn and stops by itself when the drill is done.

SPACE starts and stops; the next scramble follows.
