Rubies are a very valuable resource that can enhance your game progress and make it easier and faster. You can buy energy and dynamite with rubies, boost the crafting of items, pay with them if you don't have enough items for a workshop upgrade, or use them to fill a missing order for the merchant or shaman.
You can also buy decor for your Home Island using rubies. In a nutshell, they are very useful gems!

To get rubies you can:
- Complete tasks on your Home Island and quest islands;
- Participate in events;
- Watch ads:
- from the seashell in the right part of the island;

- If you see the exclamation mark on the icon of the ruby − it means, that you can watch an additional ad from the store
