Slot Machines are a mini-game found in the Casino.
The player can bet either 10 or 100 Qi coins when using a slot machine. If the results match one of the winning lines, the player receives a multiple of their bet. If there is no match the player loses their bet.
Roll Probability

All probabilities are independent of each other except Parsnip and Single/Double Cherry (due to specific ordering within the code).[1]
