Peek-A-Boo Poker is just like regular video poker, except that it's particularly sleazy. Along with Bubble Bath Babes, and Hot Slots, this is one of three "adult" titles for the NES released by Panesian in 1991 and features sprites of frontal female nudity. Panesian games are among the hardest NES games to find. Due to their adult nature, along with the fact that they were not licensed by Nintendo, sales and distribution were very low. All three titles are among the holy grails of NES game paks.
