请问HN：你们对这种新型魔方变体有什么看法？
考虑一个类似魔方的拼图，最开始是全黑的。当你打乱它时，会引入颜色。
具体来说，每一面都有一个与其中心方块相关的独特颜色，中心方块上用字母表示：B代表蓝色，G代表绿色，Y代表黄色，O代表橙色，R代表红色，W代表白色。
你可以像操作魔方一样旋转每一面。你还可以点击某一面来切换该面上的颜色，具体操作如下：黑色“贴纸”会变成该颜色，而该颜色的“贴纸”会变成黑色。
例如，点击一个标有R的面会将该面上的红色贴纸变为黑色，同时将黑色贴纸变为红色。（其他颜色的贴纸保持不变。）
要解决这个拼图，你需要将它恢复为全黑的状态。
顺便提一下，Gemini已经将这个拼图编码为一个单独的网页，你可以直接尝试。

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.
