Slot Gambler is a slot machine simulator with sliding puzzle elements. It was developed by Cream and published by Nichibutsu in 1995.
You play as a guy who travels around the world, gambling and meeting girls. Whenever you win a level or a sliding puzzle, you get to see an erotic picture. After beating the game, I use a cheat code to show all images, which includes those already shown during the playthrough, as well as alternative pictures for other choices I didn’t make.
