Fortune's Wheel Casino

The atrium held a solid-gold statue of an arcanoloth with an illusory fountain spraying out gold coins.

Past the atrium was the casino itself, full of boxy clockwork machines (slot machines) which a night hag celebrating a recent jackpot explained to the party. Mixed in were gaming tables of various sorts (a card game run by a vampire croupier) and a roulette wheel run by a spectator wearing a rigid 20-sided die costume would roll itself on the table. 

The party saw in the distance a huge speciality roulette wheel (an earlier version of which the casino was named after), but there was a line so the party tried to slot machines and gaming tables first. Fulton won 15 chips playing roulette, but the party mostly lost money on the slot machines and other card games though a few players won small gold rings (worth 15gp) and Sandro was zapped with a gout of flame. A githzerai named “Rule of three” always bet three chips and rolled three dice, and a mind-flayer named Ignatius Inkblot was investigating fraud at the casino and recommended the party speak aloud rather than use telepathy because it was easier for the casino to spy on telepathic communications.
