Game's features are:

WILD: Wild symbol substitutes for any symbol except for: FS.

ACCUMULATION FEATURE: An accumulation bar is presented at the top right above the reels. Every winning spin fills 1 part of the accumulation bar. A sequence of 3 winning spins triggers ADVANCED MODE. Progress of the accumulation resets to 0 if the current spin doesn't provide a winning combination.

ADVANCED MODE: During ADVANCED MODE:

• WILD symbols might be stacked by 2 or 3 symbols;
• CASCADE FEATURE is available.

Every non-winning spin decreases current accumulation progress by 1. Every winning spin completely fills up the accumulation bar.

CASCADE FEATURE: The feature is available during ADVANCED MODE only (both in a base game and free spin). Feature starts by occuring a win combination. During the feature:

- symbols that do not participate in a winning combination explode and disappear, leaving space for new symbols falling from the top;

- symbols that participate in a win combination, WILD symbols and FS symbols will stay on the screen.

Feature goes on until:

- none of the current winning combinations have been improved after symbols explosion;

- the matrix is fully blocked by a symbols that participate in winning combinations.

FREE SPINS: 3, 4 or 5 FS symbols start FREE SPINS mode. Player should select 1 symbol to define number of spins. FREE SPINS are played for free on the same bet as mode was started with. During FREE SPINS the accumulation bar is blocked. If FREE SPINS were started with active ADVANCED MODE, then the ADVANCED MODE rules are also applied.
