When i try to complile it says

SlotMachineReel.java:175: missing return statement

I think its because all my returns are in "if" statements and it needs a default return.

line 128

&

line 175

Thanks in advance for any help

* <p>
* Note that, for any payouts involving a single coin, the COIN must be
* showing on the center reel (just as shown above).
* <p>
* Since this slot machine earns 216 tokens per cycle through all
* permutations, but pays out only 192 tokens for the same cycle,
* it has a ~89% payout rate.

* Returns a number between 0 and 70 as given in the PAYOUT column above.
* Returns 0 if no payout match is found, meaning the player lost his
* initial bet.
