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.

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).

Write down a time prediction on the scorecard and try to get a solve faster than or equal to the predicted time. If the solve is slower, the result is DNF.
