This achievement should only take a few minutes. Start up the first chapter "Last Call" and in the bar go to the arcade machines. One of them is a black jack machine. Save your game in front of the machine. Now do the following until the achievement unlocks:

1. Bet everything you have
2. Play
3. If you win, save. If you lose, reload the previous save
4. Go to step 1

For a short explanation of the rules of Black Jack, go to or read the quote below.

"The basic rules of the game involve adding the value of an initial two card hand in hopes of being dealt a value of twenty-one. If a value of less than twenty-one is dealt, the player may choose to be dealt single cards until they either reach a value of twenty one, reach a value they feel comfortable to play, or reach a value that exceeds twenty-one. The winner holds a hand with a value of, or nearest to, twenty-one without exceeding it." - Wikipedia
