Chattogram Cube Open 2025

A scintillating 7.32 second winning average from Avirup Das in the classic 3x3x3 Cube capped off two intense days of solving at the Presidency International School. The Chattogram Cube Open 2025 delivered high-speed drama across ten distinct disciplines from September 26 to September 27, 2025. Das also recorded a single of 7.09 seconds during the 3x3 results chase, setting the tone for a weekend where 51 competitors took on 20 rounds of high-pressure turning.

The gathering in Chattogram, Bangladesh showcased remarkable versatility as several athletes took home titles across multiple formats. Beyond his 3x3x3 Cube victory, Avirup Das topped the podium in both the 4x4x4 Cube with a 32.85 average and Pyraminx with a 3.75 mark. His 4x4x4 Cube victory came down to the wire, edging out Arnab Banik by just five hundredths of a second as Banik posted a 32.90 second average to claim the silver position.

Arnab Banik enjoyed his own dominant run in the larger hardware categories. Banik secured three individual victories over the weekend, capturing the 5x5x5 Cube title with a 59.50 average, the 6x6x6 Cube crown in 2:07.49, and the 7x7x7 Cube final with a time of 3:15.67. His steady execution across the big cubes kept him ahead of fierce challenges from Mazba Hossain and Arash Zuhayr Udoy.

Short-format speed was equally sharp in the 2x2x2 Cube, where Hasnine Rashid secured the top spot on the podium with a 2.03 second average and a single of 1.55 seconds. Das took second with a 3.39 average, while Muntazim Billah Nazif completed the podium at 3.43 seconds. In Megaminx, Mosfikul Islam emerged triumphant after posting an impressive 38.61 average to close out the two-round event.

The blindfolded categories demanded extreme concentration, requiring complete memorisation before executing moves without sight. SM Abeer Ullah proved unbeatable in this domain, winning the 3x3x3 Blindfolded event courtesy of a 40.41 single solve. Ullah also stood out in 5x5x5 Blindfolded, recording a winning single of 17:23.00 as the only competitor to successfully finish an attempt in that demanding single-round contest.

Behind the top podium spots, dramatic individual development took centre stage during the cubing competition. Ahmad Muhtadin Alam made massive strides by trimming 39.8 percent off his Pyraminx personal best with a 3.83 single, while slashing his 3x3x3 Cube best to 9.35, which was 36.9 percent faster than before. In the same vein, Muhammad Mushfiqur Salehin tackled seven events, logging a 5.58 Pyraminx best that was 34.5 percent quicker, while Izma Farheen improved her 3x3x3 Cube mark by 36.5 percent to 47.73 seconds.

Fresh faces and ambitious expansions into new puzzles defined the rest of the field at this WCA competition. Mohammad Nafil Munawar made his official tournament debut across five events, securing 5th place in the 2x2x2 Cube alongside a 4:48.79 blindfolded effort. Tazrian Siddique debuted with a 1:06.60 in the 4x4x4 Cube, while Abdullah Anam Bhuiyan recorded a 53.75 in his first 4x4x4 attempt. MD Hasibur Rahman registered a Megaminx time of 3:42.58 in his maiden run, and Asad Mahmud dropped his 6x6x6 Cube best by 22.7 percent to 2:27.18.

The high volume of personal bests and event debuts demonstrated the vibrant growth of speed cubing in the region. Every single podium position across all ten events went to athletes representing Bangladesh, reflecting deep national talent across short puzzles, large cubes, and blindfolded formats alike. The weekend proved that technical progression remains rapid among both seasoned title contenders and ambitious newcomers.

As the Chattogram Cube Open 2025 concluded, the standard of competitive Rubik's Cube solving in the country reached fresh heights. Between the multi-event triumphs of Das and Banik and the sweeping wave of personal bests throughout the roster, the speedcubing community leaves Chattogram with tremendous momentum for the rest of the competitive calendar.
