Frequently asked questions
The essentials about slot machines, in plain language.
What is a slot machine's RTP?
RTP (Return To Player) is the percentage of wagers a machine pays back on average over the very long run. A 96% RTP means 96 returned for every 100 wagered. It is a statistical average, never a per-session guarantee.
How does a slot machine work?
Every spin is produced by a certified random number generator (RNG), independent of previous spins. Symbols stop at random and wins depend on the combinations and the game's paytable.
What is slot volatility?
Volatility describes the trade-off between how often and how big wins are. Low volatility pays small amounts frequently; high volatility pays rarely but can deliver very large wins. It is independent of RTP.
Are slot machines rigged?
On certified games, no. The RNG is tested by independent labs such as eCOGRA, iTech Labs or GLI, and the RTP is verified. Outcomes stay random and the house edge is built into the game.
What is a good RTP?
An RTP above 96% is considered fair, and some games exceed 97 or 98%. A higher RTP lowers the house edge over the long run, but never guarantees a win.
Can you predict or influence a slot machine?
No. The RNG makes each spin fully independent. No strategy, no hot-or-cold notion and no timing changes the odds of a spin.
