Spinfinity Cubes challenges players to solve increasingly complex spatial puzzles by rotating and un-rotating a cube of letters using only HTML and CSS. Each level presents a set of letters that must be arranged in a specific order by rotating the cube to align them correctly. The catch? Every letter on the cube rotates with it, so players must strategically place letters in the un-spinning inner divs to keep them facing forward. With 50 levels of increasing difficulty and a variety of cube configurations to explore, Spinfinity Cubes is a unique and challenging puzzle game that will keep players engaged for hours.
