Golden Pig Machine

The Golden Pig Machine is an item in Angry Birds Epic that the player gets after passing Level 3 of Golden Fields. It is used to roll for strong weapons and offhand items. The items' strength varies from 0 to 3 stars. Sometimes the items that you've already got are rerolled.

Cheap Roll
The Cheap Roll is worth 3 Lucky Coins. With it you have a normal chance of getting strong items. It also slightly fills up the Rainbow Bar (which we'll get to shortly).

Expensive Roll
The Expensive Roll is worth 20 Lucky Coins. With it you have a high chance of getting strong items. It also greatly fills up the Rainbow Bar.

Rainbow Bar
The Rainbow Bar is a bar that's filled up when doing rolls. As soon as it's filled up, you get a 100% chance of getting a Legendary Set Item with the next roll.
