     - 3a2) Puzzles must be fully operational, such that normal scrambling is possible.
     - 3a3) Polyhedral puzzles must use a colour scheme with one unique colour per face in the solved state. Each puzzle variation must have moves, states, and solutions functionally identical to the original puzzle.
-- 3d) Puzzles must have coloured stickers or coloured tiles.
+- 3d) Puzzles must have coloured parts, which must be one of the following: coloured stickers, coloured tiles, coloured plastic, or painted/printed colours. All coloured parts of a puzzle must be made of a similar material.

Modified versions of puzzles are permitted only if the modification does not make any additional information available to the competitor (e.g. identity of pieces), compared to an unmodified version of the same puzzle.

Modified versions of puzzles are permitted only if the modification does not make any additional information available to the competitor (e.g. orientation or identity of pieces), compared to an unmodified version of the same puzzle.

     - 3j1) Puzzles are permitted to have reasonable wear, at the discretion of the WCA Delegate.
     - 3j2) Definition: Two pieces are similar to each other if they are identical in shape and size, or mirrored in shape and identical in size.
