Xi Tan (谭熙)

Skewb · top 4.1% of 73,281 all-time · competing since August 2019 · 2019TANX01

Xi Tan (谭熙) has been competing for 7 years. His best event is the Skewb: a personal-best single of 2.81, set at Shenzhen Nanshan Open 2024, puts him in the top 4.1% of the 73,281 people who have ever been ranked in the event, and 221st in China. Until February 2014, no official Skewb solve in the world had been that fast. Across 12 competitions since August 2019, he has put 257 official solves on the record across seven events. Solve to solve, his 3×3 times vary about 16% around a typical one; 93% of the 35,811 competitors with ten or more counted rounds hold a tighter spread. His Skewb best has come down from 3.99 in August 2019 to 2.81, a 30% improvement. Xi has entered twelve competitions, more competitions than 94% of everyone who has ever competed.

Best single per competition, Skewb. Faster is higher — the axis is the right way up.

The story so far

Competitions

Reading this page: a single is one solve's time · an average is the middle three of five solves, best and worst discarded · a PB is a personal best · a DNF (did not finish) is an attempt with no valid result: a popped piece, an unsolved face, an over-limit memorisation · top X% compares against everyone ever ranked in that event, which is fairer than raw rank because event pools differ tenfold.
