There is currently one slot machine in-world, as a technology test.

It costs 10 tokens to play.

Winning combinations

Banana, any, any - 10T
Banana, Banana any - 20T
Three Bananas - 100T
Three Tokens - 1000T
Three Rings - 10000T
Any other three matching symbols - 500T
Banana, Apple, Orange - a special prize that may change monthly.

Bananas crop up frequently on the reels; other symbols less so…

Reels are a predefined sequence of symbols, of different lengths and composition. The position each real stops is chosen by a cryptographically secure random number generator, and no other algorithms. The results are thus totally random, and not subject to any rationing, percentage payouts, or similar mechanisms used to cheat you out of your hard earned tokens. There is no mechanism to force a particular result (which would have helped me in testing!)
