Blackjack

Blackjack is a card game in Fallout: New Vegas, playable in any of the six working casinos. Playing 10 hands of Blackjack grants you the Double Down achievement/trophy.

Rules
All casinos in New Vegas use 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 "double for less", 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).
 * A card is dealt to the second hand of a split before the player is allowed to act on the first.
 * The player may only double the first of two split hands (X360 - it grays out the double down option, but you can still do it on either hand).
 * 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 the table felts in each casino floor.

 * The dealer will hit any 17 containing an ace on tables where they must hit soft 17, even if its not soft 17 (for example: a king, a six, and an ace).
 * The cards may sometimes be dealt glitched or seemingly facedown, and in either case the value cannot be read.
