The Megaminx is a dodecahedron-shaped twisty puzzle, similar to the Rubik's Cube, but with 12 faces instead of 6. Each face features a different color, and the goal is to align all the colors on each face. The puzzle consists of 50 movable pieces, including 20 corner pieces, 30 edge pieces, and a core. To solve the Megaminx, players typically use algorithms and strategies that involve rotating the faces to position the pieces correctly. It offers a unique challenge for puzzle enthusiasts and is popular in competitive settings, with various speedcubing events dedicated to it.
