If you're interested in referring your friends to the game, simply click on the slate icon located at the bottom left corner of the game screen. From there, select "Friends" and navigate to the "Redeem" section.

Once you're in the "Redeem" section, you have two options. You can either click on "invite friends" to share your referral link or copy your referral code from the opposite side.

It's important to note that the referral code is only valid for new users and can only be entered after completing the tutorial at the beginning of the game. Once that phase is over, the opportunity to enter the referral code is lost.
