Skulls and Souls Bonanza Coin Grid

Secondary Pattern Matrix is a unique two-layered payout system that introduces a distinct 3x3 grid separate from the main reels. Symbols landing on the primary game grid can carry special "cards" that are then transferred to this secondary matrix. When specific patterns (such as full rows, columns, diagonals, or other defined shapes) are completed on the secondary matrix, players are awarded fixed stake multipliers. This feature provides an additional and visually engaging way to win beyond traditional paylines or bonus games.

Hold and Respin, or 'Hold & Win', is one of the most popular core bonus game mechanics in modern slots. The essence of this feature, unlike traditional free spins, is to 'Hold' bonus symbols on the reels and 'Respin' the remaining empty spaces to fill up the screen. This system was popularized worldwide through 'Money Train 2's' 'Money Cart Bonus' and is the foundation for numerous developer-specific brand features like Wazdan's 'Hold the Jackpot™' and Playtech's 'Fire Blaze™'.
