Cubing Rajarata Open 2023

Inside the halls of Anuradhapura Central College, the tables were set for a multifaceted display of speedcubing prowess. The atmosphere in Anuradhapura, Sri Lanka on April 5, 2023 was shaped by the distinct rhythm of contrasting disciplines, where competitors shifted between lightning sprints on miniature layers, the deep calculation of efficiency trials, and the measured cadence of big cubes. With 49 competitors tackling six separate events across nine packed rounds, the gathering tested the full breadth of modern mechanical puzzle solving.

The traditional Rubik's Cube drew the largest contingent of the day, featuring all 49 entrants across two competitive rounds. Sujan Irosha Kumarapperuma delivered the defining 3x3 results of the meet, capturing first place with a winning average of 9.40 seconds and posting the day's best single of 8.05 seconds. Yifan Wang took the second step on the podium with a 12.20 average, while Mevindu Bashitha Rajapaksha secured third place with an average of 13.07 seconds in the final round.

Beyond the classic cube, the schedule demanded immediate adaptation across wildly diverse formats. The 2x2x2 Cube tournament delivered exceptionally fast turnarounds, where Benul Uthsala Subasinghe clinched victory with a blistering 2.70 winning average alongside a best single of 2.46 seconds. Kumarapperuma followed in second with 5.42 seconds, and Rajapaksha took third with a 5.80 average. The triangular Pyraminx added another rapid dimension, with Kumarapperuma winning the final on an average of 4.33 seconds, narrowly edging Wang's 4.69 and Arun Kannan's 6.43.

The variety deepened as solvers faced constraints of physical technique and cognitive planning. In 3x3x3 One-Handed, Arun Kannan demonstrated steady control to secure first place with a 20.90 average and a single of 16.93 seconds, finishing ahead of Kumarapperuma's 23.03 and Wang's 26.14. Moving up in puzzle scale to the 4x4x4 Cube, Kumarapperuma dominated the field of 20 competitors with an average of 35.54 seconds. In 3x3x3 Fewest Moves, a discipline where solvers spend an hour charting the shortest possible solution on paper, Kumarapperuma won with a best single of 46 moves ahead of Dulina Harshitha Pieris at 50 moves and Hirosh Nividu at 58 moves.

Across the broader field, several competitors delivered massive leaps forward that revealed the true depth of progress on the day. Manija Kalansooriya registered an astonishing 61.6 percent improvement on the 2x2x2 Cube to set a personal best of 3.17 seconds, while also cutting their 4x4x4 Cube personal best by 53.3 percent down to 1:11.56 and trying 3x3x3 One-Handed for the first time with a 29.20 mark. Sasvidu Praveen Pathirana made a remarkable 52.7 percent drop to achieve a 2x2x2 Cube personal best of 6.06 seconds and trimmed their 3x3x3 Cube personal best by 17.7 percent to 31.43 seconds. Manitha Hasaral carved 28.8 percent off their 2x2x2 Cube best down to 5.22 seconds, alongside making first attempts at both 3x3x3 One-Handed at 1:11.84 and 4x4x4 Cube at 2:40.19. Nadeesh Peiris improved their 2x2x2 Cube mark by 38.1 percent to 6.61 seconds and took fourth place in 3x3x3 Fewest Moves.

The spirit of trying new formats continued with Saniru Sandes Bandara Sarathchandra, who entered six different disciplines, placing fourth in 3x3x3 Fewest Moves while logging first-ever attempts in Pyraminx at 52.62 seconds, 2x2x2 Cube at 6.17 seconds, and 4x4x4 Cube at 1:18.12. Dinula Guruge completed a first official Pyraminx solve of 8.74 seconds while slicing 26.3 percent off their 3x3x3 Cube best to reach 22.57 seconds. Chamindi Anupama Weerasinghe achieved personal bests in three separate puzzles, taking 19.1 percent off their Pyraminx mark to record 25.40 seconds and 8.9 percent off their 2x2x2 Cube time to finish with 8.38 seconds. Sahas Thathmira Bandara Palihana made their debut at an official WCA competition, competing across four events, finishing sixth in Pyraminx, and registering first attempts of 12.06 seconds in 3x3x3 Cube, 6.46 seconds in Pyraminx, and 4.01 seconds in 2x2x2 Cube.

The overall podium distribution highlighted strong regional engagement, with Sri Lankan solvers earning 12 podium spots, accompanied by 4 for China and 2 for India. The single-day speed cubing programme pushed participants to demonstrate agility across differing rotational mechanisms, varying layer counts, and distinct problem-solving constraints, all in rapid succession.

As the tables were packed away at Anuradhapura Central College, Cubing Rajarata Open 2023 wrapped up having showcased the immense scope of the activity. From single-handed turns to calculated geometric routes, the cubing competition celebrated versatility across the entire discipline, establishing a vibrant benchmark for the sport in Sri Lanka as solvers look forward to the next season.
