Modern slots often give you a choice: Grind the base game hoping for 3 Scatters, or Pay 100x your bet to trigger the bonus immediately.
Which is smarter? This calculator compares the upfront cost of buying against the estimated “Wagered Amount” required to hit the bonus naturally.

The Math: Opportunity Cost
Option A: Buying (100x)
- You pay $100 instantly.
- You get the bonus immediately.
- Downside: You miss out on any base game wins you might have collected while spinning.
Option B: Spinning
- If the Bonus Frequency is 1 in 150.
- You expect to wager $150 (150 spins x $1) to hit it.
- However: During those 150 spins, the RTP (e.g., 60% in base game) returns ~$90 to you.
- Net Cost: $150 – $90 = $60.
In this scenario, Spinning is cheaper ($60 net loss vs $100 cost), but it takes time. Buying is a “premium service” for impatient players. Use this calculator to see the math for your specific slot.
