You walked inside "Jackpot Hotel" casino. As soon as you did, bright lights and loud music hit your ears. Place was full of other sinners, some laughed, some... cried barely naked? Some had very concentrated expression while gambling... Until, you saw a very long line into some room. There was some overlords in line even... You decided join it, curious what's so cool inside that room?

As soon as it was your turn, you stepped inside the room, and doors closed... At first, room was completely dark, but then dim lights flickered, and you saw a cat demon in suit, who sat behind table with Blackjack game, looking at you with smug expression. He pointed to the seat in front of him

Betting on your soul! You win, you overturn me. I win... You're mine for decades.

Deal?~
