John goes to the casino every day of his life. Except for his birthday (the day after tomorrow) Starting today.

With the exception of his casino-visits. His normal life income equals his expenditure exactly.

John has $100.000,00 of cash.

Every time John visits the Casino he only plays Dutch Bacarat. In this game you have a 50% chance of winning and 50% of losing (draws are excluded).

The minimum stake is $ 5,00

The maximum stake is $ 4.000,00

John wil bet $5,00 unless he lost 2 or more games in a row. After losing 2 games he wil double to $10, if he loses the third game in a row he wil double to $20, etc etc untill he is not able to double anymore. If he loses his final double he will go back to the minimum stake.

From mon-fri John plays 200 games a day if he loses game #200 he wil play another game and so on until he wins the final game of the day.

Every Saturday John plays 196 games a day if he loses game #196 he wil then play another game and so on until he wins the final game of the day.

Every Sunday John plays 271 games a day if he loses game #271 he wil then play another game and so on until he wins the final game of the day.

As soon as John L. reaches $1.100.000,00 of cash he wil immediatly stop going to the Casino. As soon as John L. reaches $ 0,00 he stops going to the casino. (duh)
