Popular online gambling software provider, Rival Gaming, has informed its affiliates by email that its licensed casinos will no longer be accepting any new players from the United States with effect from Sunday, 7th August, 2011.

It has, therefore, been necessary for affiliates programs to send out statements to all their members informing them that some of their brands will be working off the Top Game platform.

A statement from AffiliateWide, read "We have received notification from our software provider, Rival that as from 7th August we will no longer be able to accept new US player registrations. Please note your exiting US players will still be able to deposit and you will continue to earn commission on player generated revenues."

Three online casinos currently represented by AffiliateWide, namely Spartan Slots, Box24 Casino and Black Diamond Casino have revealed that they will be changing to the Top Game brand.

Players will be able to continue playing Rival Games until such time as migration to the new software platform takes place by 15th August, 2011.

Another affiliate program, Deck Media NV, which handles marketing for Desert Night Casino and Slotocash, contacted its affiliates this week and said "We already have a plan of action to keep existing players depositing and earning your commission," it read. "We invite you to subscribe to our revamped weekly newsletters so that you can stay tuned to all retention and conversion campaigns we are running for your active players and new potential customers."
