Mainstreet Affiliates


Mainstreet Affiliates, also known as Millionaire Webmasters, is a casino affiliate program that promotes a family of US-facing RTG casinos including Sun Palace Casino and Slots Plus Casino. The group is one of the longest-running in the industry with a history leading back to 2002. The brand offers players an extensive line of slots, video pokers, and table games, as well as a few other casino specialties. A selection of these games can be played on mobile devices.

Commission details

Members of Mainstreet Affiliates make money through a revenue sharing plan based on net revenue. They are paid lifetime commissions on this revenue, which is calculated as gross gaming profits minus bonuses and chargebacks. How much an affiliate receives of this revenue as commission is determined by the revenue tiers outlined by Mainstreet Affiliates. Higher monthly net revenue means a higher commission percentage.

Mainstreet Affiliates provides its affiliates with favorable terms that ensure all affiliates can consistently earn commissions. There is no negative carryover, except for players deemed high rollers. Under this rule, Mainstreet Affiliates can quarantine a player whose average betting activity is much larger than average, and track his or her winnings or losses separately with negative carryover. There is also no bundling.

This is the only commission scheme offered by Mainstreet Affiliates at this time. No alternative plans like CPA or CPM are available.


Mainstreet Affiliates enables its partners to earn extra through a sub-affiliation scheme. Through this, affiliates can refer others to the program and receive a secondary commission equal to a flat share of all their referrals’ income.

Payment details

Mainstreet Affiliates has a highly favorable payment policy. Affiliates only have to earn $50 in order to qualify for a commission. No admin fee is deducted from these commissions, and those who don’t reach the threshold will simply have their earnings rolled over. The finance team ensures that all payments are issued by the 5th of each month.

Partners of Mainstreet Affiliates can choose to receive their commissions through bank wire transfer, check, Neteller, or their player account at one of Mainstreet’s casinos. All payments are issued in US dollars only, so affiliates who do not use the dollar will need to consider any applicable foreign exchange fees.


Mainstreet Affiliates relies upon the in-house affiliate platform provided by Real Time Gaming. This software offers partners player reports, access to integrated promotional materials, and simplified commission payments.
