Mag-Nif Inc. Four Square Puzzle is an ingenious little puzzle. The pieces will remind you of four ice cubes that appear stuck together with an olive oil frozen in one of the cubes. The puzzle looks great but it isn’t immediately clear what the purpose of the ball is.
At first look, it seems impossible to move the ball from one cube to another. However, the objective of the puzzle is to free the ball. Once you look at the edges closely, you’ll be able to notice that there are areas that have thin cracks while others have none at all.
All you need is to twist, push or slide the pieces. Eventually, you’ll be able to open the cube and set the ball free. However, the fun doesn’t stop there and the really enjoyable part begins when you put the pieces back together.
