3D Cube — Learn & Timer のアプリ分析 11月9日

Is there a real cube somewhere that you gave up on? Show its six faces to the camera and the app reads the colors, then tells you the very next move. ■ Solve your real cube — just scan it Show each of the six faces to the camera and the colors are read into the app. Press Hint and it tells you what to turn right now to solve that exact cube. Turn it in your hand, press Hint again, and keep going until it is solved. If a color is read wrong you can fix it by hand, and a cube that cannot be solved is refused with the reason why. (It catches what the eye misses, like a sticker put back the wrong way round.) ■ Learn — if you've never solved one A 7-stage course takes you all the way through a 3×3. Read the explanation for each stage, then tap an algorithm and the cube performs it for you. Practise that stage alone, and clearing it unlocks the next. There is also a 5-stage 4×4 course, and each stage shows picture cards — "this shape, this algorithm". ■ Hints — if you get stuck See the next move and the reason behind it. Hints follow the method you were taught rather than the shortest solution, so every hint doubles as revision. The net view highlights the piece you should be looking at. Hints work on 3×3, 4×4 and all four special puzzles. ■ Practice — if you can already solve it Scramble and time 2×2, 3×3 and 4×4. 15-second inspection, personal best, ao5 and ao12. ■ Special puzzles Try the Mirror Cube, Pyraminx, Skewb and Megaminx. Each comes with scrambles, a timer and records, plus hints and a learning course. ■ Make it yours Choose a color scheme or a picture skin. Picture skins can spread one image across a whole face or repeat it per sticker. ■ Also · The net view shows all six faces at once — no turning it round to check the back. · Swipe controls and notation buttons both work. · Dark and light themes. · Available in 14 languages. · Choose from six cube-turning sounds. · No internet connection required.
