Stuck on a scrambled cube? Turnsmith shows you how to solve it, one quarter turn at a time, on a 3D cube that turns exactly like the one in your hands. COPY YOUR CUBE Paint the colors face by face while the cube on screen turns to show you which face comes next. Tap to paint, drag to paint a whole row, and undo anything. If a color is wrong, Turnsmith says where: which color is counted twice, which piece cannot exist, and which square is probably the culprit. FOLLOW THE MOVES Every move is shown on the 3D cube with a brass arrow, in words ("the right column goes up, away from you") and in notation. Go at your own pace, set how long each move holds, step back, scrub, or turn the view with a finger. Solutions for the 3x3 are about 20 moves, worked out in under a second, entirely on your device. A TWISTED CORNER? A FLIPPED EDGE? If a piece was turned or popped out by hand, Turnsmith spots it, solves everything else, and tells you exactly which piece to fix with your fingers. LEARN TO SOLVE IT YOURSELF Eight short lessons for the 3x3 and four for the 2x2 teach the beginner method, each with demos and practice cubes. Coach my cube solves your own cube the same way, lesson by lesson. TIME YOUR SOLVES A competition-style timer: hold to start, 15-second inspection with calls at 8 and 12, +2 and DNF, sessions, averages of 5, 12, 50 and 100, a chart and your full history to export. Optional Game Center leaderboards and achievements. PATTERNS AND FLAGS Checkerboards, cube in a cube, the superflip and more, plus flags from around the world. Play any pattern from a solved cube or straight from your own, undo it just as quickly, or design your own and let Turnsmith find the moves.
