Under a minute, blindfolded
The world record tables, as recorded in August 2026, list the 4x4x4 blindfolded single at 51.96 seconds, held by Stanley Chapel of the United States and set at a 2023 competition named in the tables as 4BLD in a Madison Hall.
The single figure covers everything. Memorisation and execution are timed together in blindfolded events, so the 51.96 seconds includes the period spent studying the scrambled puzzle before the blindfold goes on. Nothing is stopped and restarted; the clock runs from the first sight of the cube to the last turn.
What blindfolded solving involves
The memorisation phase is a translation exercise. Solvers convert the positions of the pieces into letters using a standardised scheme, known as Speffz, that assigns a letter to each coloured sticker position, and then commit the resulting sequences to memory as letter patterns.
The execution phase runs blind. The solver applies planned sequences of moves from memory, without seeing the puzzle, and cannot check progress along the way. On a 4x4x4, with far more pieces to encode than on a standard cube, the memorised list is correspondingly longer, which is what makes a sub-minute result remarkable rather than merely fast.
Who keeps the records
Speedcubing records are not self-reported. The World Cube Association, founded in 2004, is a non-profit body that organises competitions and ratifies results, maintains the regulations and the official rankings, and recognises seventeen official events held across more than a hundred countries.
That structure is why a time like 51.96 seconds can be stated flatly. It was set at a registered competition, under the association's regulations, with judges and scramblers present, and it remains in the tables until someone beats it at another registered competition.
Where the record sits
The tables put the 4x4x4 blindfolded mark alongside the rest of the sport's frontier. In August 2026 the 2x2x2 single record stood at 0.39 seconds, held by Ziyu Ye of China; the 3x3x3 single at 2.76 seconds, held by Teodor Zajder of Poland; and the 3x3x3 average at 3.51 seconds, held by Yiheng Wang of China.
The historical comparison is starker still. At the first world championship in 1982, Minh Thai won with a single solve of 22.95 seconds on a standard 3x3x3, with full sight of the puzzle. Four decades later a competitor can solve a larger cube, blindfolded, in roughly twice that time.
What is documented — and what is not
The firm fact is the record itself: 51.96 seconds for the 4x4x4 blindfolded single, credited to Stanley Chapel of the United States, set in 2023 and listed as the standing world record in the tables compiled in August 2026.

Does the time include memorisation?
Yes. In blindfolded events the clock runs from first sight of the scrambled puzzle, so memorisation and execution are timed together.
How does blindfolded solving work?
Solvers encode the positions of the pieces as letters using the Speffz scheme, memorise the sequences, then execute planned moves without seeing the puzzle.
How old is Stanley Chapel?
No source in this record gives an age or date of birth. The source used here is a record table, not a profile.
Who ratifies speedcubing records?
The World Cube Association, a non-profit founded in 2004 that runs competitions, sets regulations and recognises seventeen official events in more than a hundred countries.
