We're spoiled for choice when it comes to games nowadays; new apps come out every week, and there are hundreds of development companies working around the clock to create the most addicting, entrancing, and entertaining distractions possible. Games are as old as humanity itself, but we haven't always had such a wide variety of them; for thousands of years, we made do with just a handful of brain-teasing puzzles. These games were challenging enough to carry on down through the generations, and their influence is still occasionally seen today. Zengrams ($0.99), by Gameblyr, is one such example; it takes inspiration from ancient Chinese tangram puzzles. Translating to “seven boards of skill,” tangrams consisted of seven flat geometric shapes; the goal was to use all of the pieces to completely fill a larger outline. Tangrams are some of the most famous dissection puzzles on earth; from the seven standard shapes, there are over 6500 configurations currently known.
