I have been composing music and making sound effects for slot machine games for almost 3 and a half years. This means different genres of music, including friendly/fun enjoyable music, as well as various styles of sound effects, win sounds, open/close sounds and others that you mentioned.
All games with my music and sounds can be previewed and played through links in my portfolio.
To make it easier for you i will point out the games that i think are similar to what you are looking for. In my "Slot games AUDIO" folder in portfolio, on youtube link you check out games called "Exotic Fruit", "Monster Munchies" and "Sushi Cuties".
