Fruit Machine - Java with Android extension

MVP: Create a fruit machine in Java.

create a simple piece of software that will operate a fruit machine.
the FruitMachine class should:
- be well tested
- have a spin() method that returns an integer value
  - return zero if all symbols are not identical
  - return winnings based on the symbol visible
- allow a player to nudge and hold at random times
- update and store a players winnings

Project Extensions

Allow users to choose from Symbol Packs (Different games.)
Extend to 5 reels
Turn into an Android app.

Planning

Two proto-personas, a gambler and a machine owner, with associated user journeys
CRC cards to plan out classes and general structure
Sketched wireframes for the Android app
Waffle.io to keep track of progress

I would have liked to

Find a way to use dynamic layouts to give a choice of five (or more) reels as the Java code was already functional
Work out how to get a consistent display on tablets and phones
Have a way to record player spend and stop when they reach their daily limit

I learned

I have a long way to go before I understand layout inflaters, view inflaters, and adaptors in Android
Smaller methods and layouts make things a lot easier
