100% free prediction game
No money required. No credit card. Just like filling out a March Madness bracket or picking NFL winners on ESPN. Free to play, always.
School staff aware
School counselor reviewed this and confirmed: as long as it's on personal devices and stays respectful, we're good. Same format as fantasy sports brackets students run every year.
Built for every grade
Freshmen, sophomores, juniors, seniors — everyone is welcome. You don't have to be in Senior Assassin to participate. Spectators often make the best predictors.
Community-powered
Students report scores, suggest markets, and help keep data accurate. This platform runs because the community keeps it running. Not one person.
Educational value
Prediction markets teach probability, data analysis, and critical thinking. The same technology is used by financial institutions and regulated exchanges like Kalshi.
Common questions
Is this gambling?
No. This is a free prediction game — identical to March Madness brackets, ESPN Pick'em, or fantasy football leagues that millions of students play every year. No money is required to participate.
Do I have to pay anything?
No. The entire platform is free. You make predictions, earn points for accuracy, and compete on the leaderboard. The prizes are funded by the organizer, not by participants.
Has anyone at school reviewed this?
Yes. A school counselor reviewed the platform before launch. It's a student-built prediction game — the same type of bracket/prediction challenges that students organize every year for sports seasons.
What grade do I need to be in?
Any grade. Freshmen, sophomores, juniors, and seniors all play. You don't have to be in Senior Assassin — spectators and other grades often make the best predictors.
What skills does this teach?
Probability estimation, data analysis, and critical thinking. Prediction markets are used by universities, research institutions, and regulated financial exchanges. This is an educational application of the same technology.
Who built this?
A student at LHS as a technology project. The platform uses professional-grade tools: Next.js, Supabase, and Vercel — the same stack used by companies like Netflix, Twitch, and GitHub.
Is my data safe?
We only collect a username and display name. No email required, no personal info. Your votes are public (everyone can see who voted what) but that's the game.
Can I delete my account?
Yes. DM the organizer and your profile + votes will be removed.
What if someone is being inappropriate?
Report it at /assassin/report. There's a content filter on confessions. The organizer reviews everything and removes anything that crosses the line.
It's free. It's fun. It's just predictions.
