The Arduboy is a credit-card-sized open-source handheld, and GameScrobbler tracks over 120 games made for it. Despite its tiny single-button-friendly form factor and monochrome display, the library spans homebrew puzzlers and arcade-style experiments like Circuit Dude, PiCross, and Crates 3D. It's a favourite among hobbyist developers who build and share compact titles, and browsing this collection gives a sense of just how creative miniature game design can get.
