Random Probability & Percentages

thingiverse

In the game, there's a 10% chance of winning when all 10 catches are open; this probability increases to 11.1%, 12.5%, and 14.3% as you close off 1, 2, or 3 catches, respectively. The chances continue rising, reaching a 50% chance of winning when only 2 catches remain open, while all winnings are guaranteed when just 1 catch is available. Printing Makerbot's "cool gray" play field as one solid piece is recommended, with the white parts being removable. A YouTube video (http://www.youtube.com/watch?v=l6KNXAu21XA) demonstrates this setup further.
