Tower of Doom is an unlicensed Intellivision-to-NES port of the game of the same name present in the Intellivision 25 Video Game System NES-on-a-chip plug-and-play. Unlike the original Intellivision version, it has been severely cut down, with only one stage present. As such, the game also loops the same stage endlessly.

Winslinator completes the single stage in record time.
