Rules
The goal
Get closer to 21 than the dealer without going over. Number cards count face value, J/Q/K count 10, and an Ace counts 1 or 11.
Your moves
Hit: take another card.
Stand: keep your hand.
Double: on your first two cards, double your bet and take exactly one card.
Split: with two cards of the same value, split into two hands with a second bet. One split per round. Split aces get one card each. A 21 after a split pays 1:1, not as blackjack. You can double after splitting.
Insurance: when the dealer shows an Ace, pay half your bet. It pays 2:1 if the dealer has blackjack.
Surrender (Main and Guest only): before you act, give up the hand and get half your bet back.
Payouts
Win pays 1:1. Push returns your bet.
Blackjack (Ace + 10-value card on the first two cards) pays 3:2, or 6:5 in OG mode.
The dealer checks for blackjack right away.
The dealer
The dealer stands on all 17s. In OG mode the dealer hits soft 17. The game uses a 6-deck shoe that is reshuffled when fewer than 80 cards remain.
Modes
Main: saves to your account. If you drop below 10 chips you are refilled to 1,000. Ranks, bosses, missions and the season pass live here.
Guest: a separate chip pool. It is not saved and never touches Main.
OG: start with 500, no refills, 6:5 blackjack, no surrender. When broke, the loan shark lends 200 and you owe 300 within 6 hands. Wins pay him first. Miss it and it is GoFundMe time.
Ranks and bosses
You earn XP every hand: 10 for playing, +15 for a win, +40 for a win of 200 or more, +60 for a blackjack. There are 10 ranks. Beat the current boss by winning 5 hands against them. The next boss unlocks as your rank rises. "Today's card" on the home screen gives bonus XP once a day, and the bonus grows with your daily streak.
Missions and season pass
Main mode gives 3 new missions every day for bonus XP. The season pass earns points on every hand: 10 per hand, +10 per win, +30 per blackjack, +40 per mission. Its 10 tiers unlock dealer taunts, card backs and themes.
Slot machine
Pick a bet of 10, 50, 100 or 500 and pull the lever. Only the middle line pays. Two matching symbols on the left pay x2. Three matching symbols pay: 7 x150, crown x60, sword x30, star x18, heart x10, spade x6.
