Cubesmith recently released a new sticker, that when looked at from different angles can change the shade at which the stickers appear to be. I was wondering if these stickers are allowed in a WCA competition considering: 3c) Competitors must use any colour scheme for cube puzzles, as long as the puzzles show one colour per face in solved state. For other puzzles competitors must use any variation that has the same moves, positions and solutions as the original puzzle. Oh, and by the way it seems more proper to use "May" in this clause instead of the first "must." I know that there are very specific rules when using these words (as well as "can" and "should"). The word "must" means that you [b:34y99b6c][i:34y99b6c][u:34y99b6c]HAVE[/u:34y99b6c][/i:34y99b6c][/b:34y99b6c] to do something (while "should" is a lesser form of this word, you're not completely obligated like must). May means that you have permission (Can=ability). In cases like this clause the proper word to use is may. "May" should (not must) be used whenever a word like "any" is used later in the sentence. Thank You

[/quote:1pq5l1om] Well, I would think 3d makes it obvious they're not. 3d) The colours of puzzles must be solid, the same per colour, and clearly distinct from other colours. [quote="Roboguy777":1pq5l1om]Oh, and by the way I've noticed in several clauses in the Regulations, WCA uses "must" when it seems more logical and proper to use the word "may"(This clause being an example). I know that there are very specific rules when using these words (as well as "can" and "should"). The word "must" means that you [b:1pq5l1om][i:1pq5l1om][u:1pq5l1om]HAVE[/u:1pq5l1om][/i:1pq5l1om][/b:1pq5l1om] to do something (while "should" is a lesser form of this word, you're not completely obligated like must).

[/quote:1pq5l1om] No, for 3c, it's an absolute requirement that everyone does this, so "must" has to be in there somewhere. Don't get hung up on the word "any", that doesn't necessarily remove obligation. For example, in Tic-Tac-Toe, for your move, you [b:1pq5l1om]must[/b:1pq5l1om] choose any of the empty squares. Just like in the regulations, you "may" have a logo on your cube, but it's not required. Solid color scheme, that's a must.

In 3c the WCA is giving us [u:35207yg8]permission[/u:35207yg8] to use any color sceme we want, under the conditions that "the puzzles show one colour per face in solved state." Going along with your tic-tac-toe example, this is different. In that sentence you are giving the instructions that you chose one of the squares to make your mark. The sentence could be split in two, to: "On your turn you [b:35207yg8]must[/b:35207yg8] make a mark in one of the empty squares. You [b:35207yg8]may[/b:35207yg8] make your mark in any empty square. The clause isn't telling you that your cubes have to have a color scheme, they're saying that any color scheme is accepted. The second "must" is used correctly, though. It's not really [i:35207yg8]that[/i:35207yg8] important, it's just grammatically correct. It still makes sense as it is, but it' just one of those things. ___________________________________________________________________________________________________ And I apologize. I said in my original post that this mistake was used in other spots on the Regulations document. I was wrong. I went through most of the document and this was the only case I could find. The reason I thought that there were more was because I posted a form concerning clause 3j and I mentioned this mistake. Then when I went to see if shade shifting stickers are allowed, I saw the mistake again and I didn't realize that it was the same clause I used in 3j. I will change my mistake on the post

It says that any color scheme may be used AS LONG AS IT ...etc.

[quote="blade740":1c6s6ctm]It says that any color scheme may be used AS LONG AS IT ...etc.[/quote:1c6s6ctm] Uh... so... are you criticizing me for saying "under the conditions that" instead of "As long as" like the original clause said or are you...? Please clarify. I was paraphrasing or whatever its called and it wasn't in quotes...
