Goal: Turn the whole top yellow from the “fish” pattern with R U R' U R U2 R'. 3 tasks · ★★★ = fewest moves.

Your cube, unfolded

Goal

Your moves

Algorithm

    Keyboard: U D L R F B turn a face, with Shift for the prime (U'). Y turns the whole cube. Backspace undoes.

    💡 Need a hint?

    The fish has one yellow corner on top. Turn U until that corner is at the front-left, then do R U R' U R U2 R'.

    What you learn here

    With the yellow cross done, count the yellow corners on top. With exactly one (a fish shape), hold that corner at the front-left and do R U R' U R U2 R' — the top becomes all yellow. If a fish appears again, just repeat.

    Algorithm: R U R' U R U2 R'
