How to Find Meter Speed
Watch the jackpot meter as you play. Track how much you bet and how much the meter increases.
Example: If you bet $20 and the meter goes from $85.00 to $85.20, the meter increased by $0.20.
Meter Speed = $20 ÷ $0.20 = $10 per $0.01

Understanding the math behind Must-Hit-By progressives
Must-Hit-By (MHB) progressives are jackpots that must pay out before reaching their maximum value. This creates a mathematical advantage when the jackpot is close enough to its ceiling.
1 The Math Behind It
Since the jackpot can hit anywhere between current value and MHB, we calculate the midpoint as the expected win.
Based on meter speed, how much total betting is needed to exhaust the meter.
The expected loss from the base game's RTP during the chase.
Average Win - Base Game Loss = Your edge (or loss)
Always use the minimum bet to reduce variance. The meter increases based on total coin-in, so smaller bets mean more spins and a smoother ride to the jackpot.
