Tell Me What You Know About Spin-Cation Slot Championship

[winddawn]

I received a Carnival casino email today that states, " Sail on any Carnival cruise departing from the U.S. now through September 2018 for a chance to win your seat in our exciting IGT Spin-Cation Slot ChampionShip with a prize pool starting at $150,000 and growing." The email was actually an offer for a "Dealers Choice" offer which sounds like a typical casino discount that's not very exciting, and this was stated at the bottom of the email. Does anyone have any information about what a "Spin-Cation Slot Championship" is? That's a new one on me. I already have a Carnival cruise booked during the stated timeframe, so I didn't get excited about making a booking. TIA for any info.
