This is a redo of a project I worked on over a year ago. The old one was laggy, slow, and inconsistent which basically means it didn't work. Here I have been able to reduce the lag, speed it up considerably, and have it work every time as it's supposed to.

The idea was to take the regular and simple Minecraft slot machines and make one as close to a real one as possible. I used one that I actually own as an example. Most of the ones in Minecraft take one credit, they randomly spin the reels and then if the middle lines up you win, if not you lose, and that felt very binary to me. To change this I gave the machine the ability to take 1-3 credits, which depending will not only check the middle row but also the top and bottom rows, and both diagonals. On top of this instead of just either you win or you lose there are different ways to win, 4 different ways, each giving out more or less prizes.

The redstone is complex but the game is simple, hopefully you can enjoy testing your luck.
