To use supply and Raid - start by going here

The number of times you can raid is once per supply that you have, you start with a small stash of supply

To raid the Vault click as shown below

Then confirm

It will then show you what you got, this can be coal, Star rubies, EP, Ancient coins, or any of the other prizes. Coins are the only prize to not be an in game thing, those are intended to send to others.

To Send Coins

As mentioned above, coins are intended as a type of vote system, you should send these to whoever you are willing to support. People such as myself are collecting these coins trying hard to win the event grand prize, additionally sending coins helps further the bar to bring us closer to winning the game wide prizes.

To actually send these coins click as shown below

Select the number of coins you desire to send, then type the name of the person you are sending them to, an example is shown below

You will now click confirm

You should get a confirmation that it was sent, showing the name of the person you sent them to.

Unless you spend cash in the store, ($10 is supposed to give you a coin)

Or buy supplies ($10 gives you 10 supplies and a $5 credit)

Then you are done,

That said you can always trade the stuff you found for other stuff, such as if you want more glowing potatoes instead of the coal ect. lots of people are willing to trade items for other items.

I hope this guide helped someone out there
