Tetris game is around for 30 years. It is still alive in various forms and shapes. It is simple and addictive. You can get it as portable game devices, apps for smart-phones or PCs. Or you can make one by yourself with few building blocs and a bit of code.
jollifactory has shared his Tetris game project that he built by using Arduino Nano board, couple chain-able bi-color matrix matrix modules, speaker and four push buttons. It looks great when placed in custom blue acrylic enclosure.
