The famous Monty Hall game where you get to decide whether to swap or hold after your first door choice.
It's a great game for demonstrating probabilities and how the best strategy is not always the most intuitive strategy.

This game will allow you to play single games or up to 10 million games in a matter of seconds in order to help discover the best strategy when playing the Monty Hall game.
The simulation will allow you to decide on a number of games to play as well as the strategy for each game(hold/swap/random choice of doors).

You might for instance want to run a million games choosing to hold on every game and then discover within seconds, once the games have run, how many of these games you have won.

Both the game and simulation show metrics for the number of games played and won together with the strategy chosen, so that you can discover which is the best strategy for playing the game.
