Berkeley January Weekday Tricubealon 2025

A winning average of 9.67 seconds defined the standard for single-handed dexterity on January 31, 2025. Solving the classic Rubik's Cube with only one hand demands exceptional ergonomic control, rapid table-turning strategies, and flawless lookahead to keep move counts minimal. At the ASUC Student Union: Martin Luther King Jr. Building, Tilden, the single-day Berkeley January Weekday Tricubealon 2025 gathered 25 competitors across seven total rounds of focused action in Berkeley, California, USA.

The 3x3x3 One-Handed event proved to be a premier showcase throughout its three scheduled rounds. Anto Kam (甘浩東) of Hong Kong took command of the event from the outset, eventually securing the gold medal with a dominant 9.67 average in the final round alongside a round-best single of 8.35 seconds. United States competitor Henry Helmuth locked down second place with a 12.05 average, while Ethan Jan captured third place with an average of 13.07 seconds among the 21 competitors.

Ethan Jan turned around to dominate the standard 3x3x3 Cube event, delivering a consistent performance across two intense rounds. Jan claimed first place in the final with a winning average of 7.38 seconds, powered by a 7.08 single. Micah Yeo earned the silver medal with an average of 7.98 seconds, while Calix Tang rounded out the podium in third place at 8.46 seconds across a competitive field of 24 entrants.

Earlier rounds of the main event produced several outstanding times in the broader 3x3 results table. Jan posted an exceptional 6.12 single and a 7.18 average, while Tang notched a 6.79 single and a 7.26 average. Yeo also put together a 7.20 single and 7.63 average, contributing to a fast sequence of times from the American contingent throughout the day.

Anto Kam added a second tournament victory by sweeping the 3x3x3 Blindfolded division. Requiring total memorisation of piece orientations and permutations before donning the blindfold, the discipline tests cognitive recall under strict time pressure. Kam won the event with a final average of 21.61 seconds and a blistering 18.41 single. Calix Tang took second place with an 18.52 mark, while Ethan Jan collected another podium finish in third with 45.06 seconds.

Beyond the top steps of the podium, several competitors achieved remarkable milestones across the tournament schedule. Chris Lillios dropped their 3x3x3 Cube personal best to 21.29 seconds, marking a 12.4 percent improvement over their previous 24.29 mark. Diego Jiashu Jiang (蒋佳澍) lowered their 3x3x3 One-Handed personal best to 23.52 seconds, an 11.8 percent drop from 26.68. Wilson Alvis (陈智胜) improved their 3x3x3 Blindfolded best to 1:11.84, which was 5.1 percent faster than their prior 1:15.73 mark, while also finishing fourth in the event. Rithwik Gupta tackled three events, finishing sixth in blindfolded solving and logging a first ever attempt in 3x3x3 One-Handed with 46.44 seconds.

The tournament also welcomed debutantes and seasoned speedcubing participants pushing into new categories. Xu Wei Kun (徐維昆) took part in their first WCA competition, recording a first ever attempt of 12.74 seconds on the 3x3x3 Cube and 46.30 in 3x3x3 One-Handed across three events entered. Geonhu Park also attended their first competition, notching a 15.20 in the 3x3x3 Cube, while Nigel Tan completed their first tournament solve with a 58.41. Meanwhile, Varenya Jyotiraditya registered a new 3x3x3 One-Handed personal best of 15.10 seconds and took eighth place in the event.

The cubing competition concluded with a final medal tally reflecting strong international representation, as competitors from the United States secured seven podium places and Hong Kong earned two. With seven full rounds packed into a single Friday, the Berkeley January Weekday Tricubealon 2025 delivered a high-quality demonstration of technical speed cubing in the Bay Area.
