Tringo is a puzzle video game that combines elements of both Tetris and bingo. It was originally developed by Nathan Keir and became popular as a mini-game within the virtual world of Second Life before making its way to the Game Boy Advance (GBA) in 2005. Players are tasked with placing shapes on a grid with the goal of forming complete squares or rectangles, which then earns them points. The GBA version of Tringo challenged players with an addictive and strategic gameplay experience, set among simple graphics and controls optimized for the handheld.
