RT Equal7 logic game

This transparent logic puzzle from Recent Toys is a cube that contains seven smaller dice. The aim is to move the small, dice-like cubes inside the large one so that the numbers on the faces of each side add up to seven. Because one space is always free, the other cubes can slide around, much like a classic sliding puzzle.

To change the position of the small dice, simply rotate the large cube. The game offers several difficulty levels, from the easier 12 and 11 challenges to the demanding 10 and 7 tasks. It is a good way to train spatial thinking and patience, with new solutions to find at every level.
