Thank you! Yes unfortunately it's a bug with the perks system that I only caught after the game was submitted. As mentioned in the description, in the intended version of the game there are 7 rounds to defeat. I created 3 different difficulty pools for the dealers to ratchet up the difficulty over time. The first round is always against Rick, and then you have 3 easy pool rounds, 2 medium pool rounds, and 1 hard pool round. This text isn't verbatim what's in the game, but here's all the dealers that can appear:

• START - Rick, the Relaxed: No power. Goal: win 5 hands.
• EASY - Katherine, the Menace: dealer draws cards 25% slower. Goal: timer is +10 from the start of the session
• EASY - Vicky, the Crusher: Player blackjacks are no longer an auto-win. Goal: win with dealer bust 5 times.
• EASY - Pedro, the Wall: player cannot double any soft values. Goal: Win 10 hands.
• EASY - Sammie, the Analyst: if dealer's score is 16, they stop drawing cards and round is a push. Goal: win 5 hands without taking cards.
• EASY - Daryl, the Destroyer: Player blackjack does not pay extra money. Goal: Win 7 hands with 3+ cards.
• MED - Jared, the Needle: lose extra money on dealer blackjacks. Goal: get 3 player blackjacks.
• MED - Alex, the Grifter: if dealer busts with 22, round is considered a tie. Goal: win 5 doubles against the dealer.
• MED - Greg, the Specialist: Player now loses on ties if they have doubled. Goal: win 5 doubles.
• MED - Seth, the Big Blind: dealer does not check for blackjack. Goal: win 3 doubles when the dealer’s first card is a 10 or Ace.
• HARD - Matthew, the Degen: all win/loss values are doubled. Goal: lose 10 hands with a score between 16 and 20
• HARD - Rachel, the Reserved: Player cannot hit if their score is 12 or higher. Goal with 7 hands.
• HARD - Troy, the Intern: whenever player hits, 15% chance to lose $2. Goal: make a flush, straight, or three of a kind with your two cards and the dealer's first card.

I also created 25 different perks, and thankfully all of them can be previewed if you play the game enough. You just can't use them sadly.

But I appreciate you playing the game!
