Gambling Session Calculator
Introduction
This purpose of this page is to calcualte various statistics for a table game session. It is designed for land-based casinos, but if you properly change the hands per hour, it will be quite-appropriate for online gambling too.
To use the calculator, select a game from the pulldown menu. That choice will propogate the hands per hour, house edge, and standard deviation fields. If you feel any of these are inaccurate, change them as you wish. You will have to put in the bet amount and hours played yourself.
When the input looks correct, click calculate and the calculator will tell you:
- Total standard deviation = This is a measurement of the volatility you can expect. You can ignore this field if you don't understand it.
- Probability win: Probability of showing a profit over the session
- x% chance to win this much or less (negative = loss): There is an x% chance you will win this much or less If the number is negative, it indicates a loss.
