Systems and methods for facilitating a game incorporating blocks of symbols

1. A method for facilitating an online wagering game, the method being performed by a processor utilizing instructions of a game engine software module, the method comprising:

(a) determining that a special symbol which functions to trigger a block of symbols to be placed into a symbol matrix is part of an initial outcome for a game event, wherein the block of symbols comprises at least one symbol that (i) occupies a plurality of symbol positions within the symbol matrix when an entirety of it is positioned within the symbol matrix and (ii) is manipulated as a single unit;

(b) placing the block of symbols into the symbol matrix along with regular symbols;

(c) determining, after the block of symbols has been placed into the symbol matrix, that at least one winning combination of symbols has been created along at least one payline of the symbol matrix as a result of the block of symbols being placed into the symbol matrix;

(d) removing from the symbol matrix all regular symbols which are part of the at least one winning combination of symbols while maintaining the block of symbols intact even if the block of symbols was part of the at least one winning combination of symbols;

(e) removing, as a distinct step from (d) and irrespective of whether the block of symbols was part of the at least one winning combination of symbols, a portion of the block of symbols from the symbol matrix, the portion corresponding to one symbol position occupied by the block of symbols, thereby stepping the block of symbols out of the symbol matrix by one symbol position;

(f) placing replacement symbols into each symbol position which has been vacated as a result of (d) and (e);

(g) determining that at least one winning combination of symbols has been created along at least one payline of the symbol matrix as a result of the placement of the replacement symbols; and

(h) repeating (d), (e) and (f) until an end condition occurs.

2. The method of claim 1 , wherein at least one of the special symbol and the block of symbols is a wild symbol.

3. The method of claim 1 , wherein the block of symbols comprises a single symbol which spans a plurality of symbol positions along at least one of a single row and a single column of the symbol matrix.

4. The method of claim 1 , wherein (e) comprises removing the bottom-most portion of the block of symbols from the symbol matrix by moving the block of symbols in a downward motion out of the symbol matrix.

5. The method of claim 1 , wherein (f) comprises moving symbols from symbol positions above the vacated symbol positions down into the vacated symbol positions.

6. The method of claim 1 , wherein the end condition comprises (i) no additional winning combinations of symbols being created as a result of an immediately preceding cascade of symbols; and (ii) a placement of and additional block of symbols not being triggered as a result of the immediately preceding cascade of symbols.

7. The method of claim 1 , wherein the method further comprises:

determining, via a first algorithm, that a block of symbols should be included in an outcome of the game; and

determining, via a second algorithm which is distinct from the first algorithm, regular symbols to place into the symbol matrix for the outcome in addition to the block of symbols.

8. The method of claim 7 , wherein the first algorithm also includes a determination of the plurality of symbol positions into which the block of symbols is to be placed for the outcome.

9. The method of claim 1 , wherein the method further comprises moving the block of symbols into the symbol matrix over a course of a plurality of game events of the game.

10. The method of claim 1 , wherein the game is a reel-based slot machine type of game and wherein the symbol matrix comprises symbol positions on reels of the game.
