🎁Mystery Boxes

Open your Mystery Box and receive NFT, SPH or Treasury tokens.

If you have already opened all the starter Mystery Boxes, don't forget to check for new ones. New Mystery Boxes can be obtained during community events.

After connecting the wallet, each user has access to the Mystery Boxes. Each Mystery Box contains various types of rewards such as NFT, Treasury Tokens, and Sapphires.

If you do not have Mystery Box, it's time to do something. You need to support all activities of The Old Castle Defense in Socials or Invite new Friends.

The reward is defined randomly, according to the following constraints:

1. Number of rewards: from 1 to 3

2. Number of SPH: from 1 to 20

Rare	5%	35%	60%

50% of all paid Mystery Boxes goes back to Mystery Boxes pool. Example: the price to open Common Mystery Box = $1. It means that $0.5 will go back to Mystery Boxes treasury and you will receive more in the next opening. Bank addresses TBD;
