Conditions for Participation:
To join the Jackpot Blast, players must opt in and play qualifying games.
By opting in, players accept the £0.10 side bet for the Jackpot bet, which will be deducted from every game round played. This deduction will be reflected in the player’s balance after the following game round.
The Return to Player (RTP) rate for the Jackpot is set at 80%. While the RTP for associated games may vary, such variations do not influence the Jackpot itself. Players are encouraged to review individual game rules for specific RTP information per game.
The Jackpot Blast operates as a progressive system; as players place their jackpot side bets, a portion of those bets is added to the total Jackpot amount.
This feature is made available on the same terms across all Gamesys Group websites under the following names: Jackpotjoy; Virgin Games; Monopoly Casino; Rainbow Riches; Double Bubble Bingo; and Bally Casino.
Winners are chosen randomly. Progressive jackpot funds are aggregated across all Gamesys Group websites listed above.
Key Points:
Both real and bonus wagers qualify for the Jackpot side bet.
Promotional free spins will not trigger any side bet.
Jackpot Blast wins may occur during any qualifying game round, determined by random selection.
Winnings accrued from the Jackpot Blast will be credited directly to the player’s account.
From time to time, there might be validation by “Gamesys Group” and relevant software providers. Their decisions regarding wins are final, and no further correspondence will follow.
Players who opted in at the time of a Jackpot Blast win will receive a toast notification detailing the Jackpot amount won.
Please be aware that the current jackpot value displayed at the bottom of the game interface may experience a delay of 30 to 50 seconds.
The payout amount corresponds to the jackpot figure available on the casino server at the time of winning.
“Gamesys Group” strives to ensure the displayed jackpot value correlates with that on the server, although minor discrepancies may occur due to rounding.
In the event of communication issues between “Gamesys Group” and the Jackpot Blast server, access to Jackpot Blast will be suspended, and contributions or claims towards the Jackpot will be paused until regular service resumes. Players can continue playing their slot games as normal.
The list of games associated with the Jackpot may vary based on your geographical location and availability.
“Gamesys Group” reserves the right to discontinue Jackpot Blast at any time. Any contributions made to a discontinued Jackpot will be re-distributed fairly according to the circumstances.
