Tetris is hands down the best game ever made, yes I do prefer it on NES, but I always carry a gameboy and a Tetris cartridge for some on the go flow. This cartridge is fully functional, and wearable as a pendant, the bail slips inside the case and is held in place with a magnet when not in use.
Go check out a video of it in action on my instagram https://www.instagram.com/p/B8wxOMLn-Ir/
