Bubble Bath Babes, Hot Slots and Peek-A-Boo Poker are three unlicensed pornographic games made for the Famicom and Famicom Disk System developed by Hacker International and were later ported to the NES by Panesian Taiwan.
Why The Games Suck
Hot Slots is just a standard slot machine simulator with dull gameplay and some glitches.
Peek-A-Boo Poker is a standard 5-card-draw strip poker simulator with glitches, as well.
Bubble Bath Babes is a rip-off of Busta Move in terms of gameplay that also has glitches.
All three games reward you with sexual images when you get a higher score each time you play.
These games were also released in non-pornographic form, which were distrubted in the US as much as these games were. Bubble Bath Babes was re-released as Mermaids of Atlantis and was published by American Video Entertainment, the same company who published Wally Bear and the NO! Gang. Both games are identical in terms of gameplay.
All three games are incredibly rare, with their rarity said to be based solely on availability and not gameplay. They usually range for about $700-$1,200 on auction sites.
