Glossary
Terms used in the reports
- RTP
- Return to player: the share of all money wagered that a game pays back over the long run. Nitro Gaming titles run at 96.70%, a house edge of 3.30%.
- Max win
- The largest payout a single round can produce, as a multiple of the bet. Between 25,000x and 50,000x the bet, depending on the title and the mode. In buy features the maximum is 25,000x.
- Volatility (std dev)
- How widely single-round results spread from the average. Higher values mean longer runs without wins and larger spikes. Engine rates each mode Low, Medium or High.
- Hit rate
- The share of rounds that pay anything, also shown as "1 in N". A 13.12% hit rate is 1 in 7.62.
- Zero rate
- The share of rounds that pay nothing: 100% minus the hit rate.
- Sub-bet win
- A win smaller than the cost of the round.
- B/E
- Break-even rate: the share of rounds that return the round’s cost or more.
- Mean
- The average payout per round as a multiple of the bet. 0.97x corresponds to a 96.70% RTP.
- Outcomes
- The number of simulated results in the game’s lookup table. Nitro Gaming titles use 99,936.
- Distinct payouts
- How many different payout values, in 0.1x steps, fall inside a payout band.
- Effective hit rate
- How often a payout band lands, written as 1 in N rounds.
- RTP contribution
- How much of the total return comes from one payout band.
- Tail probability
- How likely a single round is to pay a given multiple or more, such as 5,000x.
- CVaR
- Conditional value at risk: the average payout across the worst 0.1% of outcomes for the operator, checked per unit of stake and in absolute terms.
- Expected tail liability
- How much of a game’s expected payout sits above a threshold such as 40x or 10,000x.
- Bet tier
- Engine’s star rating for a bet range. Games that pass a tier’s risk limits keep that tier’s full caps.
