Bonus and jackpot

On the reels of Grand Jester slot machine, you will see various classic symbols of fruits and sevens. Among them, two special images help to get more coins. The Scatter symbol in this slot machine is diamond. It is not tied to the pay-lines and gives not only the multiplication of the total bet but triggers free spins. You will receive 12 free spins, during which Joker can expand to the entire reel. Also, this symbol will remain in its cell until the end of the free spins.

You will hit the jackpot if all the reels are filled with jokers. But, keep in mind that the size of the payoff depends on the bet. By playing on the max bet, you get the whole prize, if you bet less, will receive only a small part of this prize. If you get a small prize in the main game, you can activate the risk game by just hitting the Gamble button to get a doubled prize. But remember that in this round it is possible to lose your winnings.
