Robby Mier is a former professional stunt scooter rider, software developer, and poker player who is best known as the SpinQuest owner and founder. After a rocky road, he finally launched the sweepstakes casino in March 2025.
Mier was born as Robert Mierzejewski in small-town Wisconsin in the early 1990s and raised by a single mother with three brothers. During his time as a professional stunt scooter rider, he met content creator and best friend Bluff, who is now one of the faces of SpinQuest.

Robby Mier, real name Robert Mierzejewski, is the founder and current CEO of SpinQuest, who has a rather interesting backstory. From humble beginnings in small-town Wisconsin, Mier gained recognition at a young age when he toured the world as a professional extreme scooter rider.
During this time, he met his best friend Bobby, otherwise known as Bluff. Together, the two of them would film soccer videos and other content for their Instagram accounts to promote their teams and sponsors.
A keen gamer, Mier concurrently got into monetizing his passion when playing Fortnite, also learning to develop his own software. Additionally, his passion for playing poker led him into the casino affiliate industry.
When working as a casino affiliate, he realised that influencers and content creators earned way less than the money they generated for the sites that they drove traffic to. Using his 10+ years of experience in software development and his love of casino-style gaming, Mier sought to create a site that awarded the content creators and affiliates more justly for the traffic they drove to the site.
Initially rejected by 10 banks, Mier struggled at first to fund the project, but finally launched SpinQuest in March 2025. The site carries the tagline “By Players, For Players”, and his fronted by three content creators: Bluff and Brettski, whom he cites as his best friends, and omfg_slots.
