The Double Square Puzzle is part of the traditional tangram-style puzzle family. Though the specific designer of this version isn't widely credited, it is likely inspired by ancient Chinese tangrams, which were created to engage the mind in spatial reasoning and pattern recognition. The puzzle's simplicity in design—using only geometric pieces—belies the complexity of the solution, making it a favourite among advanced puzzlers and those who appreciate geometric challenges. Tangrams have been a popular puzzle format for centuries, dating back to the Song Dynasty in China. They were originally used as educational tools to teach geometry and have since evolved into various modern-day puzzle forms, like the Double Square.
