Consider a Rubik's Cube like puzzle that starts out all black. As you scramble it, you introduce colors.<p>In particular, each side has a distinct color associated with its center square, which is indicated by a letter on the center square: B for blue, G for green, Y for yellow, O for orange, R for red, and W for white.<p>You can rotate just like with a Rubik's Cube. You can also tap a face to toggle the color on that face as indicated by the letter on the face as follows: black "stickers" turn to that color and "stickers" of that color turn to black.<p>For example, tapping on a face with R would toggle the red stickers to black and the black stickers to red on that face. (Stickers that are not black or red are unchanged.)<p>To solve the puzzle, you need to get it back to all black.<p>BTW, Gemini is good enough to code this puzzle as a single web page, so you can try it out like that.
