First Jack - You and your opponent are provided 3 cards each. Like other Black Jack, you must apply all permutation/combinations to reach your final score 21.
You will be thrown a random card apart from initial 3 for this. If this new card helps in achieving black jack score, you can keep it, but at the same time you must discard a card given at the start of the game. Bottom line; both players will have 3 cards whole time; not less, not more.
After your turn, opponent will follow suit. Whoever reaches 21 first wins the game. If you win, you will see more sensuality from girl and if opponent wins, you move one level down.
