For those of you with March Madness brackets (specifically on ESPN), my friend and I made a site that simulates the tournament thousands of times to show you:

- every bracket's chances of winning your group,

- how each outcome of upcoming games affect those chances (you don't always want your pick to win!), and

- you can also manually select the outcomes of future games to re-run the simulator with your own "what-if" scenarios.

All the probabilities and rankings update live as the simulations run, which makes for a fun visual. The simulator runs client-side.

If you don't have a group but just want to see how the site works, here's an interesting one to look at: https://madness.imranh.org/group/277:4QtbGETnmegaJZU3n5TRpn
