18+ · Educational reference, not a promotion. Examples do not describe a current Spinow offer. Definitions are general; product rules and local requirements differ.

Wagering requirement

A condition requiring a stated amount of qualifying bets before bonus-related funds become withdrawable. A 10× requirement on a 100 bonus means 1,000 in credited turnover, not a 1,000 deposit.

Game contribution

The share of a stake counted toward a wagering requirement. At 20% contribution, a stake of 10 adds 2 to credited turnover. Some games contribute nothing.

Bonus balance

Promotional funds recorded separately from ordinary cash. The displayed total balance may include restricted funds, so it is not necessarily the amount available to withdraw.

Maximum bonus bet

A promotional limit on a single stake while bonus conditions apply. It may differ from the game’s normal limit; exceeding it can affect bonus eligibility under the terms.

Bonus expiry

The deadline associated with a promotion, such as claiming it or completing its conditions. Check the exact time, time zone and consequences; different stages may have different deadlines.

Return to player (RTP)

A theoretical long-run proportion of stakes returned as prizes. It describes many plays under specified rules, not what one person will receive or a promise about the next session.

House edge

The mathematical average advantage retained by a game’s operator under its rules and assumptions. It is not a fixed charge deducted from every bet or a ceiling on personal losses.

Volatility

The degree of variation in game results. Games with similar RTP can distribute prizes differently. Higher volatility does not mean higher expected profit or that a win is due.

Random number generator (RNG)

A system used to generate unpredictable game outcomes. Randomness does not make outcomes equally likely or guarantee a profit. Game rules determine how generated values map to results.

Stake

The amount put at risk on a single bet or game round. It differs from a deposit, which funds an account, and from turnover, which adds together stakes across multiple bets.

Gross return and net result

Gross return is the total paid back from a settled bet, including any returned stake. Net result subtracts the stake. A return of 15 on a stake of 10 means a net gain of 5.

Withdrawable balance

The amount the account currently identifies as eligible for withdrawal. It can differ from the headline balance. Pending transactions, bonus restrictions and account checks may affect the withdrawal process.
