General description

The Double Stacks online slot machine has five reels. Originally, there are fifteen symbols at the screen, but each of them can become double in special situations. This means, up to thirty symbols can be imaged at the screen and each of them is able to form combinations.

Ten lines are always active on default. It is possible to stake up to ten coins from one cent to two euro per line (from twenty cents to two hundred euro per spin).

The slot is provided with stacked symbols, Wilds, Scatters, jackpots of fixed size, free spins with unusual features and other interesting options of the gameplay.

Paid combinations are formed of three-ten same elements. They have to be situated next to each other at same active line, starting from the first left reel.

Wins are calculated by special indexes from x5 to x1000. They are multiplied by the bet per line. A gambling feature is not suggested.
