There’s nothing like Tetris. Invented 33 years ago, Tetris barely needed evolve thanks to its simple ingenuity. It’s meditative and infuriating at the same time. It induces anxiety, but it also helps people that struggle with that same anxiety. You don’t need to tell anyone Tetris’ rules, because they are so simple and intuitive that anyone can quickly deduce them, simply by looking at the game in action.
