Silentia 2 - BLD 2023

Six competitors gathered on May 14, 2023, to test their memory and execution across four specialised blindfolded events. Held at Scientia Residences in Tangerang Regency, Banten, Indonesia, Silentia 2 - BLD 2023 brought together a dedicated field of solvers for a focused, single-day gathering. While small in total attendance, the meeting gave participants an intense, direct route into official competition across multiple demanding disciplines. Each event offered just a single round, meaning that every attempt carried immense weight under official World Cube Association regulations.

The specialised nature of the meet placed extreme demands on concentration and precision, as every entrant tackled variants of the classic Rubik's Cube without visual feedback during execution. Blindfolded speedcubing requires competitors to memorise the state of a scrambled puzzle before donning a blindfold and executing complex algorithms purely from recollection. For many participants looking to establish their marks in the community, this targeted format offered a rare platform dedicated purely to blind solving disciplines rather than standard visual speed solving events.

Ahsanul Insan Hamid proved to be the standout performer throughout the day, capturing top honours in three of the four events on the schedule. In 3x3x3 Blindfolded, Hamid delivered an exceptional single solve of 22.61 seconds to secure first place among the six entrants. Kiagus Ahmad Haikal Hafif Hamidy followed in second place with an average of 51.09 seconds after posting a fastest single attempt of 31.88 seconds, while Vincent Hartanto Utomo claimed third on the podium with a single effort of 1:07.52.

Hamid extended his winning run when the field transitioned to larger, more intricate puzzles. In the 4x4x4 Blindfolded event, which featured five competitors navigating additional layer parity and edge pairing from memory, Hamid clinched the victory with a top time of 2:35.57. Utomo followed in second place with a time of 5:43.48, while Singapore representative Wong Chong Wen took third place by logging a time of 8:24.93, ensuring international representation on the podium during this intensive cubing competition.

The 5x5x5 Blindfolded discipline proved to be the most demanding individual puzzle contest of the entire schedule, testing the extreme limits of memory capacity and stamina. Ahsanul Insan Hamid once again emerged victorious, navigating the extensive piece count to register a winning single of 6:40.46. Wong Chong Wen claimed the runner-up spot on the podium with a time of 17:46.00, while the remaining three competitors, Wilson Alvis, Vincent Hartanto Utomo, and Cendy Cahyo Rahmat, did not record a successful completion.

The final contest on the programme was the 3x3x3 Multi-Blind event, an endurance test requiring competitors to memorise and solve multiple puzzles consecutively in a single attempt. Vincent Hartanto Utomo took the victory in this discipline, successfully completing 7 out of 8 puzzles within a time limit of 24:10. Hamid finished in second position with a clean 5 out of 5 solved in 6:30, while Hamidy completed the podium in third place by solving 9 out of 13 cubes in 56:50.

Altogether, the tournament served as an important milestone for blindfolded speed cubing in the region, showcasing notable depth despite the compact registration list. Across the four events, Indonesian competitors captured a total of 12 podium spots, while Singapore earned two podium positions courtesy of Wong Chong Wen. The tight four-round schedule allowed every competitor on site to gain valuable official stage experience across multiple complex formats that are rarely contested in large standard opens.

When the final results were tallied at the conclusion of Silentia 2 - BLD 2023, the event stood as a testament to the skill required at the highest levels of blindfolded solving. From standard 3x3 results to the prolonged focus of multi-blind solving, each participant faced severe tests of recall and nerve. As the 2023 season moves forward across Southeast Asia, the marks achieved at this WCA competition will set a strong standard for blindfolded specialists heading into future tournament cycles.
