WitEden & Oskar Mixup Cube Series (Mixup 3x3, 3x3x4, 4x4x3 & 4x4x4) Product Overview: Designed in collaboration between WitEden and master puzzle designer Oskar van Deventer, the Mixup Cube Series represents a revolution in twisty puzzle geometry. By introducing non-standard cutting planes that allow intermediate layers to shift and misalign at 45-degree angles, these puzzles create complex shape-shifting states and deeply intricate jumbling challenges far beyond traditional cuboids. Variant Options: Mixup 3x3: The classic breakthrough design that started the mixup phenomenon, allowing edge-to-center piece swapping and fascinating geometrical distortions. Mixup 3x3x4: A rectangular cuboid variant combining standard 3x3 faces with extended 3x4 rectangular layers, adding extra layers of bandaging and asymmetric solving logic. Mixup 4x4x3: A flattened cuboid structure featuring 4x4 grid scaling on top and bottom faces paired with a 3-layer depth, providing a unique blend of parity management and mixup mechanics. Mixup 4x4x4: The ultimate challenge in the series, scaling the complex mixup and edge-shifting mechanism up to a full 4x4x4 framework for advanced collectors. Key Features: Designer Collaboration: Created by legendary puzzle engineer Oskar van Deventer and manufactured with precision by WitEden. Advanced Mixup Mechanism: Allows pieces to cross boundary lines, resulting in extreme shape-shifting and sophisticated algorithmic solving requirements. Durable ABS Construction: High-contrast colored stickers on smooth black bodies for optimal tracking during complex solves.
