Predict Challenge Win
Start a league, fill out the tournament bracket, and find out who really knows football.
Free, forever
Your version of the tournament, before kickoff
Start or join a league — private, public, two people or two hundred. Then fill out your tournament slip: who wins, with what score, who lifts the cup. As matches play out, Whiff compares your picks to reality and updates the standings.
Simple predictions
For every match, enter the score you think will happen. Whiff saves it on its own.
Your league, your rules
Invite who you want, set the rules, decide what counts as a win.
Live leaderboard
As the tournament plays out, points climb on their own.
Three steps and you're in
- 01
Fill out the group stage
For every group match, enter the score you think will happen. No need to compute the standings: Whiff applies the real tiebreakers (points, goal difference, head-to-head) and decides who qualifies.
- 02
Draw the bracket
For every knockout match, pick who wins. Teams propagate through the bracket automatically. Change your mind and downstream matches update on their own.
- 03
Watch your points grow
As matches happen for real, Whiff compares your picks with the actual results and scores them. The league leaderboard updates without you lifting a finger.
Fill out your tournament, no download required
Enter the scores you expect and watch your points climb in real time. It works exactly like the real app.

Whiff For everyone, really
If you know nothing about football
It doesn't matter. Pick by instinct, jersey colour, because your mum is rooting for the Netherlands. Luck counts as much as knowledge — the leaderboard decides who was right.
If you've never filled a slip
A Whiff slip is dead simple: for each match you enter the score you think will happen. The app guides you, saves on its own, and tells you exactly where you still need to tap.
If you're a real expert
Per-stage multipliers, champion bonus, extra time, penalties. The league creator sets the rules: play it simple, or build a scoring system worthy of a professional bettor.
You set the rules (or whoever creates the league does)
Every league has its own rules. Want a simple "1 point per exact result" scoring? Want multipliers that grow per stage? Champion bonus, extra time, penalties? Player cap? A private league among co-workers or open to everyone? It's all configurable.
