About Fantasy League Lottery

I'm RJ, a fantasy league commissioner from Toronto. Every draft lottery tool I found was basically a random number generator. You run it, screenshot the result, and hope your league believes you didn't re-roll. Some commissioners record the whole thing on video just to prove it's legit.

I wanted something better. Results that are sealed the moment they're generated. No one sees them, not even you. A reveal date the whole league counts down to. And when it hits, everyone's flipping picks together in real time. No video proof. No screenshots. No “just trust me.”

Then I went deeper. I built four weighting modes (equal odds, NBA-style, linear, and fully custom) so commissioners can match the exact feel of their league. I added pick constraints so you can lock a team into a draft range. Try guaranteeing the last-place team picks top 3. The math behind weighted lotteries with constraints was genuinely hard to get right. But after building it, it was worth it. Every commissioner now has access to the same tools the real NBA and NHL use, for free.

What started as a side project for my 12-team fantasy football league has grown into a full platform with 8 commissioner tools: weighted lotteries, live card-flip reveals, race mode, punishment wheels, toilet bowl brackets, league awards, fee tracker, and draft recaps with stats breakdowns. Every feature exists because a real commissioner needed it.
