# Increasing Percentage Gamble

Python Puzzles

Back to the Python! homepage

A casino has a new game. A gambler can bet \$10 and get a 1% chance of winning \$100. If the gambler loses, they can bet another \$10, and their chance of winning increases from 1% to 2%. After each loss, the gambler can bet \$10, and the chance of winning will increase 1%.

What is the average number of bets the gambler must place to win the \$100? Is this game in favor of the gambler or the casino?

The game is definitely in favor of the casino. On average, you would spend over \$120 to win \$100.

``Average number of bets: 12.1667``

Here is the Python code to run the simulation.

```import random

def play_game():
bet = 10
win_probability = 0.01
num_bets = 0

while True:
num_bets += 1
if random.random() < win_probability:
return num_bets, 100
else:
win_probability += 0.01
bet += 10

average_bets = 0
num_iterations = 10000

for i in range(num_iterations):
bets, payout = play_game()
average_bets += bets

print("Average number of bets:", average_bets / num_iterations)
```
