Paragon Table (right next to Item Mall and Loyalty Shop tab)
It's like a gamble box, but in a table format
it cost 200 Ruby per try (1 USD or 275 Loyalty Point)
once you get Ruby Coins, right click on them from you bag, than left click on the Ruby Coin in the Table
Than click on "Go For it", it will auto randomly pick an award for you.
If you land on one of the items, you can either Redeem or Go For it again to go to a higher stage.
However, if you land on Emerald Shard on any row, the game stops there, basically Game Over.
But you can also save up Emerald Shards to have a chance of starting your "Go For it" from a higher row.
