Glossary of terms for free slot players

Below are concise and precise definitions, with an emphasis on how the term helps in demo mode (no money and no registration).

A. Basic concepts and mathematics

RNG (random number generator) - an algorithm that randomly determines the result of each spin; backs are independent. * In the demo: works the same as in real life.
RTP (Return to Player, theoretical return) - the share of bets returned to players over a long distance (e.g. 96%). * In the demo: the indicator is identical to the version for money.
RTP ranges - the same slot can be released with different RTP (e.g. 96/95/94%). * In demo: check the value in "i "/Paytable.
Volatility (variance) - spread of payments: low = more often, less; high = rarer, larger. * In the demo: helps to find a comfortable pace.
Hit Frequency -% of spins with any win. * In demo: a benchmark for the length of sessions.
Max Win (maximum multiplier) - theoretical winning ceiling (e.g. x5 000). * In the demo: evaluate the potential of the bonus.
House Edge (casino advantage) - 100% RTP −. * In the demo: teaches you to look soberly at the odds.
Distribution - how the winnings are "scattered" across the ranges. * In the demo: the nature of the slot is visible.

B. Interface and rates

Bet/Stake - amount per spin. * In the demo: train the size of the "unit."
Min/Max Bet - available bet bounds. * In demo: useful for simulating future bankroll.

"Demos are more generous/skimpier than real" - licensed providers have the same math; only the psychology of the player is different.
"Strategy guarantees plus" - slots - randomness; strategies - about controlling the pace/risk, not about hacking mathematics.
"I'll catch the bonus on the schedule" - the trigger is unpredictable.

How to Use the Glossary in Demo Practice (Short Outline)

1. Open Paytable → mark RTP/Volatility/Mechanics.
2. Spend 200-300 spins on a fixed rate → fix Hit Frequency, Bonus Frequency, Drawdown.
3. Compare 1-2 more slots with different mechanics (Megaways vs Cluster).
4. Select the tempo and limits (Stop-loss/Stop-win) for future sessions.
