Return to player: the theoretical percentage a game returns over a very large number of plays. A 96% RTP corresponds to a 4% theoretical house edge. Use the RTP shown inside the game. The same title can exist in more than one RTP version.

What does game contribution mean?

The percentage of each bet that counts towards completing wagering. At 25% contribution, £1 staked moves the wagering meter by only 25p. Read the eligible-games section. A low contribution can multiply the real play-through.

What does expiry mean?

The time allowed to claim, use or complete an offer. Spins may expire separately from the resulting bonus balance. Record the claim deadline and wagering deadline—they may be different.

01 / term

Wagering requirement

How much qualifying play is required before bonus funds or winnings can be withdrawn.

Example: A £100 bonus with 10× bonus wagering requires £1,000 of qualifying stakes.

Check: Confirm whether the multiplier applies to the bonus only or to deposit plus bonus.

RTP

Return to player: the theoretical percentage a game returns over a very large number of plays.

Example: A 96% RTP corresponds to a 4% theoretical house edge.

03 / term

Game contribution

The percentage of each bet that counts towards completing wagering.

Example: At 25% contribution, £1 staked moves the wagering meter by only 25p.

Check: Read the eligible-games section. A low contribution can multiply the real play-through.

04 / term

Expected value

The average mathematical value across many identical attempts—not a prediction of one result.

Example: A £100 bonus requiring £1,000 of stakes at a 4% edge has a simplified value near £60.

Check: EV does not remove volatility or the chance of finishing with nothing.

05 / term

Maximum cashout

A limit on how much can be withdrawn from bonus play, even when the balance is higher.

Example: A £100 cap means any eligible balance above £100 may not be withdrawable.

Check: Look for separate limits on free spins, no-deposit bonuses and deposit matches.

06 / term

Sticky bonus

A bonus amount that forms part of the playing balance but cannot itself be withdrawn.

Example: If £100 is sticky, only eligible winnings above the non-withdrawable amount may be cashable.

Check: Confirm exactly what is removed when a withdrawal is requested.

07 / term

Qualifying deposit

The minimum or specific deposit needed to activate an offer.

Example: An offer may advertise free spins but require a £10 cash deposit first.

Check: Check eligible payment methods; some methods may not qualify.

08 / term

Expiry

The time allowed to claim, use or complete an offer.

Example: Spins may expire separately from the resulting bonus balance.

Check: Record the claim deadline and wagering deadline—they may be different.
