This simple app picks a game (somewhat) at random from the million or so games in the MobyGames, IGDB, and RAWG databases.
The goal is not so much to make decisions for you, but to give you inspiration what to play next, or inform you of cool games you never heard of.
That said, it is not ENTIRELY random. MobyGames comes up about half the time. IGDB about 1/4th. RAWG about 1/8th.
The Wheel prioritizes major releases with a decent rating, except for RAWG, where you are likely to receive some half-finished Game Jam project.
These services all have rate limits and in the case of RAWG, a lot of unreliability, so if you can't get it to work, come back later.
