Some struggle for hours to solve a Rubik’s Cube, others take minutes to do so.

Mr Daryl Tan is able to work out the puzzle in seconds – with one hand, no less – while being suspended upside down or submerged underwater.

The 22-year-old Singaporean holds 11 Guinness World Records titles for his speedcubing feats, which in itself is another achievement. No other cubing aficionado globally holds as many records.

His feats have made it to the Guinness World Records 2025 book. Released on Sept 12, the latest edition marks the 70th anniversary of the series, which has sold more than 150 million copies in more than 100 countries.

TheSingapore Institute of Technology second-year undergraduate, who is pursuing an honours degree in physiotherapy, picked up cubing when he was in Primary 6.

“My friend brought a Rubik’s Cube to school and solved it in 50 seconds. I was impressed,” recalls the St Andrew’s Junior School alumnus.

The puzzle toy, which has been around for 50 years, was invented by Hungarian sculptor-architect Erno Rubik. Beyond the classic 3x3 cube, it now comes in many variants.

Mr Tan learnt basic cubing techniques on YouTube after the PSLE, and, within a month, improved his timing from four minutes to under 30 seconds.
