Popular event games
Start with the event you are hosting.
Collective Odds works best when the questions fit the group, the room, and the moments everyone is already watching.
Why this is different
Most event polls are static. Collective Odds stays live.
Built for the moment your group is together—not a year-round platform you have to keep checking.
No app download for guests
Share a link or QR code. People open it in their phone browser and start playing — no App Store visit, no install barrier at the event.
Live predictions during the event
People can add picks and update answers while the wedding, trip, or watch party is unfolding—not on a static form beforehand.
Notifications that pull people back
Let everyone know when new predictions open, results are resolved, and standings change.
Live event leaderboards
Turn every resolved question into visible movement so the whole group stays in the moment.
Hide predictions from specific people
Make predictions about a speech, arrival, reveal, or surprise without tipping off the people involved.
Flexible question types
Support quick yes/no picks, multiple choice questions, and numeric guesses that fit your event.
Examples from real events
Try a few predictions before you host a group.
Pick an answer, stake a few points, react with an emoji, or leave a comment to see how your event will feel.
