Margin Call
PrecisionGuess the exact probability for each market. The closer you get to the real odds, the higher your score. Max 500 points.
How it works
You see a market question. Use the slider to set your probability estimate (0-100%).
After submitting, the real market probability is revealed
Points are awarded based on how close your estimate was. 100 per question.
Tips
- *Think in ranges. Is this more like 60% or 80%? Narrow it down.
- *Extreme events (very high or very low probability) are easy points.
- *The markets with the most volume tend to have the most accurate prices.
Prediction Parlay
High StakesChain predictions together. Each correct call doubles your score. One wrong answer and you lose it all. How far can you go?
How it works
Start with a base score. Each market is a new link in your parlay chain.

Cash out any time or keep pushing for a higher multiplier.
Tips
- *Start with the markets you are most confident about.
- *High-probability markets are safer but the real points come from getting uncertain ones right.
- *Know when to cash out. Greed is the parlay killer.

How it works

Bluff Detector
DeceptionSome markets show real probabilities. Others are bluffs with fake numbers. Can you tell which is which?
How it works
A market question is shown with a probability. It might be real or it might be fake.
Decide: is this the real probability, or is it a bluff?
Score points for correctly identifying real vs. fake probabilities.
Tips
- *If a probability seems too extreme for the question, it might be a bluff.
- *Think about what the real probability would be before deciding.
- *Follow prediction markets regularly to calibrate your sense of what looks right.

How it works

Decide: is the real probability Over or Under what the crowd thinks?
Score points for each correct call. The closer the margin, the more points.
Tips
- *Think about what information the crowd might be missing.
- *Markets with lower volume tend to have less accurate prices.
- *Trust your domain expertise when it conflicts with the crowd.
Survivor
EliminationA series of prediction rounds where one wrong answer eliminates you. How deep can you survive in the prediction gauntlet?
How it works
Each round presents a prediction market question.
Get it right and advance to the next round. The difficulty increases.
Get it wrong and you are eliminated. Your score is how far you made it.
Tips
- *Early rounds are easier. Save your risky picks for later.
- *When in doubt, go with the higher-probability outcome.
- *Study trends on the /movers and /hot pages to sharpen your instincts.
General Tips for Better Predictions
Understand probability
A market at 70% means the crowd thinks there is a 70% chance it happens. That also means there is a 30% chance it does not. Both sides have a real possibility.
Volume matters
Markets with more volume tend to have more accurate prices because more people (and more money) are contributing to the forecast. Low-volume markets can be mispriced.
Watch for momentum
A market that moved from 40% to 60% in 24 hours is telling you something new happened. Check the /movers page to spot these shifts early.
Contrarian thinking
The crowd is often right, but not always. The biggest opportunities come when you have a genuine reason to disagree with the consensus.
