Dincher mounted a relentless campaign across the remaining events, turning in an exceptional series of performances in both classic and mid-sized puzzles. In the 5x5x5 Cube, Dincher secured the top spot with a 50.20 average ahead of Lal in second at 51.80 and Mack in third at 53.29. The speedcubing powerhouse then swept the 4x4x4 Cube final, winning with an average of 26.82 as Mack followed in second with 27.32 and Minseo Gu completed the top three with 29.71.

The 3x3x3 Cube contest, the traditional focal point of any WCA competition, drew a full field of 61 competitors through three rounds. Dincher capped a dominant run by securing the title with a 6.47 average and a 5.88 single. Mack kept the pressure on by finishing second with a 6.69 average, while Gu took third with an 8.10 mark. The final 3x3 results cemented a massive haul for United States competitors, who earned 14 total podium spots across the day, alongside four podium finishes for the Republic of Korea.
