How to Play pokie

Grand Slam Casino is a five-reel slot that looks like a traditional game of this genre. It is possible to play only on nine paylines. The bet is made directly per spin and ranges from forty to ten thousand credits.
In addition to regular combinations, it has special symbols, mystery bonus payouts and rounds for doubling the payouts. All these options are discussed below.
At least three identical pictures are required to generate the paid sequence. As usually, they should be located continuously in the paylines starting with the first reel from the left side. Each sequence on a single position gives only one payout (the largest possible among the available ones in this case). Its sum is calculated depending on the line bet and odds, provided by the rules (exceptions are discussed below).
The total payout, credited based on the results of the spin, can be increased in the game on even chances. Gamblers need to select the red or black (circles on the main screen). If users are lucky enough, the amount is doubled. If the players fail, they lose their payouts. There is a limit for each round in the amount of one hundred total bets.
The level of the theoretical payout percentage of this model is not indicated.

Symbols, Wild, Scatter

This slot machine uses a standard set of images, including various fruits and berries, as well as a four-leaf clover and a bell.
In addition, there are two special symbols: Wild (a blue star), and Scatter (a logo of GS). They are endowed with advanced features:
  • The wild replaces the other pictures, except for the scatter. It should appear in the necessary position. Its participation generates the maximum possible combination.
  • The scatter is not connected with the active lines and is paid in any position. The payout amount depends on the total bet. Three or more such images provide the user with the bonus payout, which is called Mystery Bonus. Its size is determined randomly, but it does not exceed the limits, established for each bet.
