Blackjack

Blackjack is a mini-game based on the real-life card game, playable in any New Vegas casino with a cashier.

Playing 10 hands of Blackjack grants you the Double Down achievement/trophy.

Rule variations
All casinos in New Vegas adhere to the following rules.


 * Maximum bet is 200 chips
 * The game is dealt from multiple decks, which are shuffled after every hand
 * The player may not purchase insurance
 * Late surrender is offered on any hand
 * Blackjack payouts and surrendered bets are rounded up
 * The player may not double for less (the option to double is not available if player does not have enough chips, and the player may not re-buy mid-hand)
 * The player may only split to two hands
 * The player may only split identical card values (that is, the player may not split Queen-King)
 * The player may only double the first of two split hands
 * The player may draw to the second of two split hands before drawing to the first

House rules
Each casino has its own rules regarding blackjack payouts and when the dealer must draw. The rules can be seen on table felt in each casino floor.

Barring variations from Luck, the best odds are found at The Tops or Ultra-Luxe. The worst odds are found at Atomic Wrangler, often the earliest playable casino encountered by the Courier.

Rewards and bans
As the player gets more money from a casino, a floor manager will approach them, offering increasingly valuable gifts to their "lucky player." If the player progresses past all of the gifts, and accumulates too much money (the amount is different for each), then the casino will ban them from playing any more games. The player can still use all of the casino's other functions (restaurant, theater, etc.), including cashing out their chips, but is never allowed to play any money-winning game in the casino. These bans are permanent. It may be possible to avoid the bans by cashing out before winning 2000 chips in a session and moving on (unconfirmed on Xbox 360).

Appearances
Blackjack can be played in Fallout: New Vegas.
