What is the Rubik’s Cube world record, in seconds?

How to get close to this number

The turn rate is the way in. The explanation notes that top solvers execute around ten turns per second, and a well-inspected cube can be solved in something like fifty moves. Divide one by the other and you land within a couple of seconds of the answer. This is the cleanest kind of estimate available: two quantities that are easy to believe, combined by arithmetic rather than by memory.

The trap is the inspection period. Competitors get fifteen seconds to study the cube before the clock starts, and in that window an expert plans the entire opening sequence. So the recorded time is not the time to solve the cube from scratch — it is the time to execute a partly pre-planned solution at maximum speed. Guessing without knowing that rule lands far too high.

This figure also describes a single solve, which is the most luck-dependent statistic in the sport. A favourable scramble can save a substantial fraction of the moves, which is how a record can drop below the three-second barrier while the same person averages noticeably more across five attempts. Competitive rankings mostly use that average for exactly this reason, and it is worth knowing which of the two a quoted record refers to.
