Berkeley December Weekday 2025

Twenty-three competitors stepped up to the tables at Hearst Field Annex B5 on December 2, 2025, bringing compact speedcubing action to Northern California. The one-day gathering proved that a focused schedule can produce elite times, testing agility, memory, and technique across three challenging disciplines. Set in Berkeley, California, USA, the Berkeley December Weekday 2025 delivered six packed rounds of competition. While speed cubing demands raw turn speed, events emphasizing dexterity and precision pushed every solver to make each split-second motion count on the competition floor.

The standard 3x3x3 Cube event drew all twenty-three participants for a heated two-round contest that set the tone for the entire gathering. Ethan Jan delivered a masterclass in efficiency, capturing the title with a tournament-winning 6.24 average and securing a best single of 5.83. Jan maintained flawless control across all five solves in the final round to hold off a talented lineup of pursuers in the flagship division of this WCA competition.

Pushing Jan right to the wire, Heidi Chan claimed the second spot on the podium with a brilliant 6.60 average, having also posted a personal mark of 6.57 single in earlier turns. Zane Qureshi rounded out the top three on the strength of an 8.07 final average, alongside a 7.22 single during the elimination stages. The deep field generated sharp 3x3 results from start to finish, establishing high benchmarks throughout the bracket.

Solving the Rubik's Cube without sight brings a unique form of tension, and the 3x3x3 Blindfolded division featured fifteen competitors willing to face the mental pressure. Anto Kam of Hong Kong rose to the occasion in dominant fashion, securing the victory with a rapid best single solve of 22.94 seconds. Blindfolded solving requires rapid memorisation followed by pure tactile execution, and Kam navigated the sequence without a hitch to take top honours.

Ethan Jan added to an already impressive day by earning second place on the blindfolded podium with a composed 48.66 single. Naomi Solnick rounded out the medal positions in third place, recording a swift 31.01 single solve. The blindfolded event proved to be one of the most unpredictable contests of the Berkeley December Weekday 2025, rewarding solvers who balanced aggressive pacing with absolute accuracy.

Away from the top of the podium, several determined competitors delivered notable personal milestones on the tables. Bowen Deng took on three separate events and generated a dramatic breakthrough in 3x3x3 Blindfolded, logging a personal best single of 54.59 seconds to shave 28.1 percent off a prior record of 1:15.89 on the way to a sixth-place finish. Alexander Hao-Jia Du tackled two events and made significant progress in the 3x3x3 Cube, lowering a previous best mark of 14.97 to 13.25 seconds for an 11.5 percent improvement.

Progress continued throughout the roster across multiple puzzle categories. Ryan H. Lee entered two events, finishing fifth in 3x3x3 Blindfolded while setting a personal best single of 2:24.28, which was 3.6 percent faster than a previous mark of 2:29.71. Jimmy Kingston contested two disciplines and earned an eighth-place finish in 3x3x3 Blindfolded. Timothy Elnitiarta focused on a single event and secured an eighth-place finish in the 3x3x3 Cube, while veteran competitor Ryan Jew entered two events and achieved a sixth-place finish in Square-1.

The shape-shifting Square-1 puzzle capped the schedule at the Berkeley December Weekday 2025, demanding intricate algorithmic knowledge and distinct mechanical handling. Calvin Nielson controlled the final round with steady turns, taking the gold medal courtesy of a 7.50 average and a best single of 7.08. Joseph Ong earned second place with an 8.68 average, while Miguel Diaz clinched third place with a 16.97 average in the nine-person field.

With United States competitors earning eight podium spots and Hong Kong claiming one, the single-day cubing competition concluded on a high note of technical execution and personal advancement. The Berkeley December Weekday 2025 provided an ideal platform for competitors to refine their craft in Berkeley, California, USA, setting up an exciting winter ahead as the 2025 calendar draws to a close.
