Hey, hope you enjoyed the video! I'll be doing an AMA on the r/speedcubeshop subreddit this Friday at 12 PM Pacific time and it will last a few hours (until I'm tired of answering, basically 😂). I'll be giving away SCS gift cards randomly and to people with good questions, so be there or be square! Also a clarification: I cannot turn the yellow *center* which means no slice moves that run parallel to yellow (like E or wide d moves).

I tried to read a math paper like this once. Some guys proved that you can divide by 3, using Set Theory, but without using the Axiom of Choice. It's a trivial result that we know is obviously true, but the one constraint there breaks the easy method, and you have to find a new theory, sometimes substantially more difficult. And you did that here. You theorized around not turning the Yellow side, and still derived how to solve the cube, which is great! You know how to solve a cube, and one little constraint on that task forced you to find some insightful new workarounds. Very nice work!

[@JohnvanCapel]

My dumbest idea for a challenge: For each rotation you want to make, you have to instead do 3 rotations in the opposite direction. (so if you want to do an R' it's R3 instead.)

[@theomelettecuber5458]

And in case there are double turn, then we have to do that single notation six times, for example: U2=U6 Exception: back angle Ub perm ( R’ U R’ U’ *R3* U’ R’ U R U R2) which has a R3 on it and that R3 is preserved. Edit: Someone in the reply section told me to do R9’ instead of R3, he/she is a genius.

[@emilian0e]

Shut up

[@michaelacho1282]

I devised a great method for solving without turning the yellow side! For example, when you have to do a sune in last layer, but you made white as the cross color, you can just hold the sune where you need to do it, do M E2 M' E2, do the sune, then do the center changing algorithm to put the centers back in their respective sides, and the oll is complete! You can also do that for a variety of algorithms and also f2l!

[@michaelacho1282]

Plus, for U' D moves in G perm or V perm, just do it in the middle of the algorithm. And, if yellow is on top and you need to do a U' D move in let's say G perm, just do D and then center hanging algorithm, then do U' then put the rest of the centers where they belong.

Wow, that was really impressive! I love these challenges you do. For the next one, you could try to solve the cube without turning TWO sides. Here’s my suggestion: You can’t turn two opposite sides on the cube (e.g. blue/green). This will restrict the number of solvable cases, so maybe at the start of the solve you can turn blue/green, but once you’ve solved the cross you can’t turn them anymore. Will be cool to see how you approach this! It might actually make your F2L super fast considering you won’t have to make F/B moves 👀 and last layer will probably be super easy too for some reason. Hope you try it out!
