Bonus Summary
How This Calculator Works
Monte Carlo Simulation
We simulate 50,000 complete bonus sessions, each starting with your deposit + bonus and placing bets until either the wagering requirement is met or you go bust. The results show what happens on average.
Why Wagering Matters
A ₹1,000 bonus with 10x wagering requires ₹10,000 in total bets. With accumulator requirements, your effective win rate drops significantly.
Singles vs Accumulators
Singles are easier to clear - you win ~50% of bets at fair odds. Accumulators with 3+ legs at 1.40 odds each have only ~35% win rate - much harder to profit.
Time Limits & Win Caps
Strict time limits (like Parimatch's 3 days) can cause you to forfeit the bonus. Win caps limit your upside even if you get lucky. Both significantly reduce expected value.
Frequently Asked Questions
Frequently Asked Questions
What is a wagering requirement?
A wagering requirement (also called rollover or playthrough) is the number of times you must bet the bonus amount before you can withdraw. For example, a ₹1,000 bonus with 10x wagering means you must place ₹10,000 in total bets before cashing out.
How does the Monte Carlo simulation work?
We simulate 50,000 complete bonus sessions. Each session starts with your deposit + bonus, then places bets until either the wagering is complete or you go bust. The Expected Value shown is the average profit/loss across all simulations.
Why are accumulator bonuses harder to clear?
Accumulators require all legs to win. A 3-leg acca at 1.50 odds per leg has only ~30% win rate (0.67^3), compared to ~67% for singles at the same odds. This dramatically increases your bust rate.
What does 'bust rate' mean?
Bust rate is the percentage of simulations where you lost your entire bankroll before completing the wagering requirement. A 40% bust rate means 4 out of 10 players will lose everything.
Should I always take a bonus with positive EV?
Not necessarily. Consider the bust rate and time required. A +₹200 EV bonus with 60% bust rate and 30 hours of wagering may not be worth your time. Also check if you can withdraw your deposit without the bonus if you change your mind.
Why do sports bonuses have lower wagering than casino?
Sports betting has lower house edge (~5%) compared to slots (~4% but with higher variance). Bookmakers compensate with stricter requirements like minimum odds (1.40+), accumulator-only rules, and shorter time limits.
