Pals

There are a variety of ways to obtain Pals, although the most common is use the gacha machine located in the shop.

Here you can receive free draws every day for watching ads or you can use Pal coupons or diamonds.
The most efficient method is to use the Draw x35 as it only costs 30 coupons (or 600 diamonds).

When you draw you will see a screen that shows you what you have won.
The more Pals you draw from the machine, the higher the machines level.
As the gacha machine increases in level.
your chances of receiving rare Pals increase.

Pal coupons can be gained from events, quests, mining or Lucky Wheel to name a few
