How to play Blackjack on The Intergalactic Casino

First, place your bet. Next, the dealer will deal you and himself two cards. The dealer will show you one of his cards. Now, you take your turn.
During your turn you can:
Hit(Take a card)
Stand(End your turn)
Double(Double your bet, take exactly 1 card, and end your turn)
Split(If both your cards have the same value at the start, you can seperate and play 2 hands with the same bet you started with. You cannot resplit.)
Surrender(Give up half of your bet and end the game)

Then, after your turn is over, the dealer shows their card and continues drawing 1 card at a time until they reach 17 points or higher(See Values). If their total is over 21, you win. If you have more points than them, you win. Otherwise, you lose.

Object:
Have your card's total be 21 or under, and be over the dealer's total

Values:
Number cards have the value on their face
Face cards count as 10 points
Aces count as 1 or 11 points, you get to choose

Misc. Notes:
If you start with 21 points, you automatically win
In the event of a tie, you neither lose nor win money.
