The EStar SQ1 UV in the Yellow Top edition is a maglev Square-1 with a full UV coating, so its yellow top layer and bright side colours have a glossy, grippy finish. It is built for Square-1 solvers who have outgrown a budget puzzle and want a flagship they can set up exactly the way they like.

Underneath, it is one of the most adjustable Square-1s around. The upper and lower layers each have their own numbered tension settings, and axis distance can be tuned in fine, stepless increments. Magnets on two tracks and two layers, plus inner and outer magnetic rings, keep the layers aligned, and a 15° assisted recentring pulls the slice back into place after each turn.

Features:

• Maglev with dual-track, dual-layer magnets
• 15° assisted recentring for cleaner slices
• Numbered tension settings plus stepless axis-distance tuning
• Inner-track corner cutting and an outer anti-pop structure
• Full UV coating with a yellow top layer
