Frequently asked questions
Which slot providers are included?
Pragmatic Play, PG Soft, Habanero, Booongo, Playson, CQ9, Evoplay, Hacksaw Gaming, Play'n GO, Jili, Spadegaming, Joker Gaming, Amatic and more. See the providers page for the full list.
Do you offer fish games and crash games?
Yes. Fish games and Spribe mini games such as Aviator are available through the same API.
Can I test before going live?
Yes. You receive test credentials and a balance to integrate and test every game before you open it to players.
Why one API instead of separate provider integrations?
One contract, one integration and one wallet for every provider, instead of building and maintaining each connection yourself.
Which wallet type should I choose?
Seamless keeps balances in your platform; transfer moves funds into the game wallet for each session. Both use the same game API.
