When you get cubesmith tiles how do you apply them?

Question

Do you have to peel off all the stickers so it's all blank and them put them on? Or do you just place the tiles over the original sticker when the plastic film comes off?

Answer 1

A plastic razor blade is the best tool for removing the old stickers without damaging the puzzle itself. Once the old ones have been removed clean the surface of the puzzle lightly with rubbing alcohol to remove any adhesive reside and then stick the new stickers on the puzzle.
