Hey,

Not sure if there is still support for this.

But when it hits 3 iron blocks it gives an error and does not give reward.

Task #1446 for CasinoSlots v2.6.0-SNAPSHOT-b50 generated an exception

You have an invalid value for the rewards. Also, you're using an old version thus I am closing. Here on out I will only be supporting v3-snapshots, I have started some work on ensuring things work properly and without issues in the new version.
