25,000+ Simulations
We simulate the entire tournament thousands of times, score every bracket in your pool, and measure how often yours finishes first. Not expected points — actual win probability.
Ownership Modeling
If 40% of your pool picks the same champion, that pick has less leverage. We model what your opponents will pick and find contrarian selections that maximize your edge.
Pool-Size Aware
The optimal bracket for a 10-person office pool is different from a 1,000-person public contest. Larger pools demand more differentiation. We account for this.
Runs in Your Browser
The entire optimization engine runs client-side using Web Workers. Your pool settings never leave your device. Watch the bracket update in real-time as the optimizer finds improvements.
How It Works
Enter your pool settings
Pool size, scoring system (ESPN standard or Yahoo), and how sharp your opponents are.
Watch it optimize
The engine simulates 25,000+ tournaments in your browser, models your opponents, and hill-climbs to the best bracket — updating live as it finds improvements.
Get your edge
See your P(rank = 1), how much it beats chalk, and which contrarian leverage picks give you the biggest edge.
Coming Soon
Real team data launches on Selection Sunday, March 15. Right now the optimizer runs with mock teams based on seed strength to demonstrate the engine.
