📐 The Maths
House Edge = 100% − RTP%
Total Wagered = Bet × Spins
Expected Loss = Total Wagered × House Edge
Expected Remaining = Starting Balance − Expected Loss
This is the long-run mathematical average. In any single session you could win or lose more — variance determines short-term outcomes. The higher the RTP, the lower the house edge, the longer your money lasts.

Frequently Asked Questions
RTP (Return to Player) is the percentage of all wagered money that a slot machine pays back to players over time. A 96% RTP means that for every $100 wagered, the game returns $96 on average and keeps $4 as profit. It is calculated over millions of spins — short sessions will deviate significantly.
Anything above 96% is considered good for an online slot. The best RTPs are found in NetEnt classics like Blood Suckers (98%), Mega Joker (99%) and Jackpot 6000 (98.86%). Most modern slots from providers like Pragmatic Play range from 96–96.5%.
No — RTP is a long-run statistical average calculated over millions of spins. In any single session of a few hundred spins, you could win significantly more or lose significantly more than the RTP suggests. Variance (volatility) determines the range of outcomes.
House edge = 100% − RTP. A 96% RTP slot has a 4% house edge, meaning the casino keeps $4 of every $100 wagered on average. Lower house edge = better for players.
The game RTP is set by the software provider, not the casino. A Pragmatic Play slot has the same 96.5% RTP whether you play it at a crypto casino or a traditional online casino. However, crypto casinos often offer provably fair in-house games with published house edges as low as 1%.
