If you’ve played enough blackjack with Gamble-bot, you’ve realized that the computer plays by certain rules. For new players, the rules are summarized here:

1. If Gamble-Bot’s upcard is an Ace, Facecard, or Ten, then Gamble-Bot’s down card will be a ten. (95%)

2. If Gamble-Bot’s upcard is a seven, eight or nine, and the player has twenty, Gamble-Bots’s down card cannot be a ten. (95%)

3. If the player hits on twelve or more, and reaches a total of 17, 18, or 19, Gamble-Bot will end up with a total of twenty. If the player’s total reaches 20, then Gamble-Bot will make 21. (90%)

4. If the player sticks with 16 or less, Gamble-Bot will not bust. (85%)

5. If the player doubles down on eleven, the next dealt card will be a five or less. (85%)

The percentages in parenthesis is the amount of time the rule is enforced, this percent is necessary to allow the presumption of the game being fair and this all being in the players mind.

Certain other rules are yet to be discovered.
