About

Willbro

Features

Willbro turns your group chat's hot takes into a real game. Make predictions with your friends, back them with points, and see who actually called it when the dust settles. Create a Brotherhood — your private friend group — and start predicting anything: who wins the match, who flakes on Friday, whose team finishes top. Every prediction becomes a friendly market your friends can weigh in on. HOW IT WORKS • Create a Brotherhood and invite your friends with a join code. • Post predictions — simple Yes/No calls or multi-option questions. • Back your pick with points before the prediction closes. • When it resolves, winners split the pot based on how much they staked. • Climb the leaderboard over the course of each Season. SEE RESULTS, THE EASY WAY At the end of every Season, Willbro tallies everyone's net points and shows the simplest set of "who won" — so bragging rights are crystal clear. WHY YOU'LL LOVE IT • Private groups — just you and your friends, no strangers. • Fast, friendly predictions on anything you can imagine. • Live leaderboards and season results. • Comments and reactions to talk trash and celebrate wins. • Push notifications so you never miss a prediction closing. SAFE & RESPECTFUL Willbro is built for friends, and we keep it that way. You can report any prediction, comment, user, or group, and block anyone you don't want to interact with. Reported content is reviewed and objectionable content is removed. All members agree to our terms prohibiting abusive or inappropriate content. Willbro is for entertainment among friends — it does not involve real-money gambling in any way or form. Points are just for fun and bragging rights.
