RTP figures are modelling assumptions, not operator disclosures — bonus terms come from each operator’s own T&Cs. SeeMethod.

Return to player, by game type

Every figure carries a source. Where a headline RTP has conditions attached, the conditions are printed — an unconditioned “0% house edge” claim is not a fact, it is an advertisement.

Wager Lock: 100% first deposit + 20 free spins

First of three tiers (100%, then 50%, then 100%), each unlocked by a further deposit. Deposit and bonus are both moved into a locked promotional balance that must be turned over 40x before anything is withdrawable. The term that hurts most is not the multiplier: any game with RTP above 97.4% is disabled while the bonus is active, including blackjack, some live tables and all sports. That removes exactly the low-edge games you would otherwise clear on, forcing the turnover through a higher house edge. Max bet is 2% of the deposit.

Game weighting

A weighting below 100% multiplies the money you must actually stake. Zero means the game cannot clear the bonus at all.

No Wager Lock: up to 100% first deposit

Marketed as having no wagering requirement, and technically true - nothing is locked and nothing is forfeited if you stop. But the bonus is released at wager x 1% x 20%, which is 0.2% of turnover, so unlocking the full $700 takes $350,000 of betting. That is the equivalent of a 500x requirement. Meanwhile games above 97.4% RTP are disabled, so you pay at least 2.6% house edge to earn 0.2% back. No bet size can make that positive. Better than the locked version only because you may stop at any point and keep what unlocked.

20 free spins on Sweet Bonanza

Awarded automatically with the first deposit on the Wager Lock promotion, and they must be used to progress to the next tier. Winnings from the spins carry their own 40x wagering requirement, so the turnover base depends on what the spins actually return - which makes a single honest EV figure impossible to state. Restricted to Pragmatic Play titles and only available from countries Pragmatic supports. Spin value is not published in the terms.

No expected value stated

Wagering applies to spin winnings, so the turnover base is not knowable from the terms alone. A single EV figure would be invented.
