Not every game is a winner. Take the recently released The Lord of the Rings: Gollum, which was universally panned, went viral for how glitchy it was, and prompted a public apology from the game developer.

We’ve all played some really terrible games — some of them so bad that we’d be happy to get rid of them and never, ever see them again.

Legend has it one such game from the Atari era was so bad, the company actually dug up a giant hole in the desert and dumped thousands of copies into it, hoping they would never be unearthed. Frankly, there were a lot of bad games released for the Atari, but only this one carried the legend of being buried in a mass cartridge-grave in the desert.

Which game was it?
