Double Sevens is a 3-reel slot game with 5 static paylines. Winning combinations consist of 3 matching symbols along any payline. Of course, the Double Seven symbol is the highest paying symbol, but watch out for the joker symbol. He’s the wild symbol and substitutes for all the other symbols except the mystery symbol. He can occasionally stretch across all three positions on a reel; even across every position on every wheel! Winning combinations involving the joker pay double the normal prize.
Get three Mystery symbols anywhere on the reels, and you win a surprise sum that is displayed on the screen. The more you bet, the more you win as a mystery prize.
There is also a Double Up Round feature that can increase every winning combination. You can collect your prize immediately, or combine this with the Double Up Round, by clicking DOUBLE or COLLECT. The Double Up Round is where you guess whether a face down playing card is either red or black. Guess correctly and your prize is doubled! The deck is shuffled, so you always have a 50% chance of getting it right. The Double Up Round can be played up to five times in succession.
Don’t forget that massive progressive jackpot is building up on every spin too! The more you bet, the more chance you have of winning it. You’ll see it displayed at the top of the reels.
Double Sevens has an optional Autoplay function.
