You can have up to five successful friend referrals whose activity can earn you ongoing bonus units. Once you reach the maximum number of successful referrals (5), you will not earn ongoing rewards for additional referrals.
However, you can continue to earn lump-sum bonuses for additional referrals when they complete the sign-up and opt-in process with your referral link and reach Checkpoint 5 in their game of choice. Plus, your friends can always enjoy the benefits of joining Mistplay as your referral!
