5x5x5 Blindfolded

5x5x5 Blindfolded is an official WCA event requiring one to inspect a 5x5x5 Cube and once the cube is fully memorized, solve it without sight. The final time includes the time it takes to inspect and to solve added together. The solver may not have any view of the cube during the solving stage. In order to ensure that the solver is unable to see the cube during the solving phase, the judge typically places a sheet of paper between the solver's blindfold and the cube.


  • Few people have competed in 5BLD and had a successful solve compared to other events, at only ~1200 competitors ever successfully getting a 5BLD single (as of 17 Jul, 2018).

The top 5BLDer solvers today are Tom Nelson, Graham Siggins, Kaijun Lin, Cale Schoon, Stanley Chapel, and Roman Strakhov.
