NaticubeBLD 2023

Inside the quiet study halls of the Morse Institute Library, blindfolds were adjusted and timers sat waiting on December 2, 2023. Speedcubing in its memory-intensive form took centre stage as 14 competitors gathered for a day of intense focus without sight. Rather than the rapid clicking of visual solving, the venue was defined by extended stretches of quiet concentration followed by sudden bursts of execution. The single-day WCA competition brought specialized solvers together in Natick, Massachusetts, USA for a program entirely devoted to blindfolded puzzle categories across five total rounds of action.

The competitive narrative of NaticubeBLD 2023 was driven by landmark times and official record standards across the four scheduled events. The headline 3x3x3 Blindfolded competition featured multiple exceptional marks in the opening rounds, establishing new benchmarks for several competitors. Rowe Hessler turned in a blistering 21.39 single alongside a 22.34 average in the event, setting the absolute pace for speed on the day. Vishwanath Jeyaraman also recorded a remarkable single of 22.36, while Thiago Han registered a sharp 24.77 single during his run.

Further down the scoresheet, official single records continued to fall in the 3x3x3 Blindfolded division. Abner Brijesh delivered a 36.70 single alongside a 43.81 average, while Caleb Retik posted a 53.47 mark. Sub-two-minute single records were established across the board, with Patrick Collins clocking 1:12.97, Saisabari Ramesh finishing in 1:24.22, Elliot Wiecek recording 1:32.18, Daniel Winterberg stopping the timer at 1:33.36, and Ryan Durette charting a 1:59.40. These record times highlighted the rapid progression of blindfold execution throughout the day.

When the final round of the classic 3x3x3 Blindfolded contest arrived, Thiago Han of Brazil secured the top spot on the podium. Han captured the title with a winning single of 25.21, navigating two rounds among 14 entrants to finish ahead of the pack. Caleb Retik claimed the runner-up position with a time of 50.26, while Abner Brijesh rounded out the podium in third place with a 57.47. These crucial 3x3 results demonstrated how precision under pressure defines podium finishes when sight is taken out of the equation.

Beyond the standard Rubik's Cube size, the larger puzzles demanded even deeper memorisation and spatial endurance. Thiago Han earned his second victory of the day in 4x4x4 Blindfolded, claiming first place among 11 competitors with a winning single of 3:46.73. Abner Brijesh finished second in 5:18.41, followed by Caleb Retik in third with a time of 7:13.15. In 5x5x5 Blindfolded, Brijesh dominated the eight-person field, claiming victory with a best single of 10:25.00 and a winning average of 12:29.00, beating Retik's 21:38.00 and Benton Tolley's 23:32.00.

Away from the top of the podium, several competitors achieved remarkable milestones that the overall standings only begin to reveal. Daniel Winterberg took on four events, earning a 4th place finish in 5x5x5 Blindfolded and slicing his 3x3x3 Blindfolded personal best down to 1:23.39, an improvement of 28.1 percent over his previous 1:56.01. Dylan Girouard also enjoyed major personal gains across three events, cutting his 3x3x3 Blindfolded best by 16.4 percent to 1:55.39, finishing 6th, while making his first ever official attempts in both 3x3x3 Multi-Blind with 3/4 in 28:22 and 4x4x4 Blindfolded with a 25:50.00 result. Saisabari Ramesh contested four disciplines, placing 4th in 5x5x5 Blindfolded, shaving 21.3 percent off his 3x3x3 Blindfolded mark to reach 1:24.22, and dropping his 4x4x4 Blindfolded personal best by 29.5 percent down to 15:11.00.

New ventures into complex disciplines continued with Ryan Durette, who entered two events and completed his first ever attempt at 3x3x3 Multi-Blind with a 2/3 result in 13:28 alongside a 7th place finish in 3x3x3 Blindfolded. Viktor Pearl tackled three events, securing an 8th place finish in 4x4x4 Blindfolded while registering his first ever 3x3x3 Multi-Blind performance, solving 2/3 cubes in 14:23. Elliot Wiecek, Rowe Hessler, and Vishwanath Jeyaraman also delivered sturdy shifts across the weekend schedule, with Wiecek and Hessler each taking on four events to earn 4th place finishes in 5x5x5 Blindfolded, while Jeyaraman placed 8th in 3x3x3 Blindfolded.

The 3x3x3 Multi-Blind event brought a dramatic test of mass memory to conclude the cubing competition schedule. Abner Brijesh executed a flawless attempt, solving all 23 attempted cubes in 57:29 to finish clear of the 12-competitor field. Caleb Retik followed in second place with a perfect 11/11 in 52:33, while Patrick Collins took third with 11 out of 16 cubes solved in 55:43. The performance cemented Brijesh as one of the standout multi-event athletes of the meet.

By the close of NaticubeBLD 2023, the United States collected 10 podium positions while Brazil earned two victories from Han's dual gold performance. The specialized gathering highlighted the intense discipline and technical refinement required in modern speed cubing memory events. Solvers packed up their blindfolds and cubes from the Morse Institute Library, having set a high bar of records and personal achievements as the local community looks forward to the next season of competitive challenges.
