The Square-1 is one of the most unique and mechanically complex WCA official events. Unlike other cubic puzzles, the Square-1 can change its shape entirely during a solve, transforming from a cube into a scalloped or kite-shaped form. This shape-shifting nature makes it fundamentally different from the Rubik's Cube family and requires specialized solving techniques. JrTimer generates official WCA Square-1 random-state scrambles for your training.
The Square-1 consists of three layers: the top layer (containing 8 pieces), the bottom layer (8 pieces), and a fixed equator layer with a single divided piece. The top and bottom layers can rotate freely, while a vertical slice turn flips the equator. Due to the alternating large corner and small edge pieces, not all move sequences are available in non-cubic shapes ??this adds a layer of complexity absent from other WCA events.
The Square-1 single world record is 3.40 seconds by Jackey Zheng (USA), and the average world record is 4.74 seconds, also held by Jackey Zheng. Square-1 records have fallen dramatically in recent years as CSP and algorithm recognition speed improve among top competitors. Common milestones: sub-1 minute (beginner), sub-30 seconds, sub-15 seconds, and sub-8 seconds for advanced competitive solving.
Top Square-1 competitors often use the MoYu SQ1 Magnetic, YJ MGC Square-1 M, or the M-Cube Volt Square-1. Square-1 hardware matters significantly ??a well-tuned puzzle prevents slice-lock during non-cubic shape solving, which is critical for consistent fast solves.
