Playing
1) First choose a door by clicking on the numbered button (#1, #2, #3, #4) on any of the four doors. Your selection will be highlighted with two arrows.
2) Serendip will then open TWO different doors to show you that the prize is not behind those two. You are then given the chance to stay with your current door, or switch to the other remaining, unopened door. Click on either the stay or switch button.
3) Serendip then opens the door you've chosen and you either win (Serendip's logo) or lose (sad face).
4) To continue playing, click play again.
5) Use the auto-play: random, auto-play: stay every trial, and auto-play: switch every trial buttons to let the game run by itself. To stop auto-play click the appropriate button again.

- Your total trials and wins are displayed in the times played, wins, and % wins monitors.

- The % wins of each stratetgy monitor plots the wins for all trials for which you've stayed and all trials for which you've switched.
