This string game “Cuatro” is at the same time a simple but also somehow unsolvable looking puzzle. Basically, these kinds of games are considered the most difficult genre among brain teasers. Very few people can imagine what happens after they have put the string over, under or through the puzzle. Entanglements are created that require a great deal of skill to undo.
In our puzzle there is a very difficult main step, which is ingenious but also super easy (if you know it). šŸ˜‰
