Hanoi Summer 2025

0.11 seconds was all that separated the top two finishers in the 5x5x5 Cube final, delivering one of the sharpest podium battles of the entire weekend. Hoàng Hà Thủy Tiên took the victory with a 52.91 average, holding off Đặng Trần Diễn at 53.02, while Phạm Đức Phước closed in closely for third with 53.25. Held across September 20 and September 21 at AEON Mall Hà Đông, Hanoi Summer 2025 gathered 130 competitors in Hanoi, Vietnam for a packed two-day schedule spanning 13 events and 24 rounds of intense Rubik's Cube action.

The classic 3x3x3 Cube contest stood as the largest bracket of the weekend, drawing 120 competitors through three rounds of speedcubing. Phạm Đức Phước captured first place with a solid winning average of 7.27 and a best single solve of 5.95 in the final. The overall 3x3 results underscored the depth of talent present in the regional speed cubing scene, where sub-eight-second averages were required to vie for top honours at this high-energy cubing competition.

In the faster puzzle categories, the 2x2x2 Cube event saw Nông Quốc Duy claim gold with a winning average of 1.75 and a low single of 1.36 across two rounds. Phạm Tuấn Hùng finished second with a 2.72 average, while India's Shrey Relan secured third place at 2.77. The Clock event brought another razor-thin contest, where Mai Đức Nghĩa won the final with a 3.53 average, nudging out Shrey Relan who recorded 3.65, and Ngô Ngọc Hiếu who finished third with 4.45.

Big cube specialists enjoyed decisive triumphs on the tournament floor. Trương Khánh Tùng executed a dominant sweep in the largest NxN puzzles, winning the 6x6x6 Cube in an average of 1:34.99 alongside a single of 1:24.70, ahead of Đặng Trần Diễn at 1:39.75. Trương Khánh Tùng then followed up by winning the 7x7x7 Cube with a 1:59.04 average, beating Taiwan's Chao-Che Chung at 2:23.62 and Đặng Trần Diễn at 2:29.90. In 4x4x4 Cube, Trần Anh Quân topped the 81-competitor field with a 27.17 average and a 24.97 single.

Across the specialized formats at Hanoi Summer 2025, Haohan Zheng took top honours in two distinct disciplines, winning Megaminx with an average of 46.74 ahead of Nguyễn Hoàng Hải at 49.79, and securing the Square-1 title with an 8.70 average. Nông Quốc Khánh claimed victory in Skewb with a 2.90 average to edge Malaysia's Eng Dickson at 3.07. In 3x3x3 Blindfolded, where competitors must complete the puzzle purely from memory after memorising the pieces, Zaya Qiaolong won with a single time of 1:06.11. Nguyễn Văn Khánh triumphed in 3x3x3 One-Handed with an 11.54 average, while Đàm Cao Thanh Tùng topped Pyraminx with a 3.18 average.

Beyond the podium battles, several multi-event specialists delivered remarkable personal milestones on the competition stage. Hoàng Gia Huy contested nine separate events, logging a huge Pyraminx personal best of 1.96 seconds, which improved upon his previous best of 4.56 by 57 percent, while also recording his first ever official attempts in 5x5x5 Cube at 1:24.54 and Megaminx at 2:21.87. Lê Nguyễn Nhật Minh also tackled nine disciplines, finishing 7th in 3x3x3 Blindfolded while posting his first official attempts in 3x3x3 One-Handed at 21.89, 5x5x5 Cube at 1:47.15, and blindfolded solving at 1:56.53. Nguyễn Khoa Bằng matched that nine-event workload, finishing 10th in Square-1 and completing debut attempts in Megaminx at 1:08.31, 6x6x6 Cube at 2:54.64, and Square-1 at 13.93.

Other competitors similarly broadened their competitive horizons with ambitious multi-puzzle schedules. Trần Quang Anh took on eight events across the weekend, logging first career marks in 5x5x5 Cube with 2:02.85, Pyraminx with 7.99, and Skewb with 12.38. Nguyễn Công Gia Hưng competed in seven events, recording inaugural official times in 3x3x3 One-Handed at 21.09, Pyraminx at 7.28, and 4x4x4 Cube at 1:20.48. Meanwhile, Hoàng Nhật Minh completed six events, putting up debut results in 3x3x3 One-Handed at 20.36, Skewb at 6.77, and Clock at 14.50.

The international distribution of awards reflected strong local and visiting representation, with competitors representing Vietnam taking 27 podium spots, alongside podium finishes earned by solvers from China, India, Taiwan, Malaysia, and the Czech Republic. As the tables cleared at AEON Mall Hà Đông, Hanoi Summer 2025 highlighted a rich weekend of multi-event variety, tight margins, and personal milestones that will carry forward into the 2025 season at the next WCA competition.

With 130 competitors sharing the venue across two full days, the event served as an expansive showcase for both experienced contenders and solvers discovering new disciplines. The balance of rapid-fire rounds and calculated endurance puzzles proved that every fraction of a second remains vital when silverware is on the line.
