How to unlock the Lucky Winner achievement in BioShock - Definitive Guide
The slot machines are located in Fort Frolic, all the machines have the same winning percentages as any other.
There are three outcomes, based on the outcomes i got when trying this achievement and from what i have heard from others. Here is a list of what they are and there likeliness of getting.
Three apples ($25) - 30%
Two dollars ($50) - 10%
Three dollars ($250) - 2%
On average you should have to spend $500 for the jackpot (50 tries). Save before you start gambling as you may have to reload. its not to important to have lots of money to start off with, it just means you have to reload less often.
Don't forget that in this area is Cohen, you may want to also look at there "Found Cohen's Room" achievement and the "Irony" achievement if this is your first time in the area.
Once you have maxed your money at 500, find a slot machine. Save your game and play until you either get the jackpot (triple $$$) or run out of money. If you run out, reload your save and try again.
This achievement is entirely lucked-based and can be earned in seconds, or it could take you an hour. There are slot machines located sporadically throughout Rapture, but the earliest place to get this achievement is in Fort Frolic. There are slot machines in the foyer after you get off of the bathysphere but before you enter the main area and are contacted by Sander Cohen.
You will most likely waste a lot of cash while going for this achievement so it is best to create a manual save right before you start pulling the lever. Continue to pull the lever until you hit a jackpot which will shoot confetti out of the machine and award you $250. If you’ve lost any cash at that point, simply reload your save and continue on with the game.
