Solve a 3x3x3 as a team with a solver who is blindfolded, and a caller who is not allowed to touch the cube or the solver's arms below the elbow. There is no inspection time.

Solve a Mirror Blocks by feel without memorization

Using a solved 3x3x3 (A) and a scrambled one (B), bring cube A to the same state as cube B without making turns on cube B. There is no inspection time.

As a team of two, solve a 3x3x3 one step at a time using CFOP or Roux. CFOP steps: cross, 1st, 2nd, 3rd, 4th pair, OLL, PLL. Roux steps: 2x2x1, 1st block, 2nd 2x2x1, 2nd block, CMLL, EOLR, 4C.

As a team of two, solve a 3x3x3 one move at a time, alternating team members between each move. Only one team member may make a move at a time. No talking is allowed at any point during the attempt. A competitor may not undo their own move and turn a separate layer on the same turn (e.g. R R' U isn't allowed, but R R2 is).

Correctly scramble a 3x3x3 using standard WCA move notation. The competitor may inspect the scramble sequence using standard inspection procedures.

Solve a 3x3x3 in a team of two, each using only one hand. Relevant One-Handed rules apply.

Solve any side on the 3x3x3 puzzle as fast as possible.
