Big Bad Wolf Pigs of Steel Slot Machine

Wild symbols appear on all five reels, and Piggy Wilds can appear via one of the features, as we will see. Wilds of all kinds substitute for any normal pay symbol, and 5 regular wilds pay 40x the bet, while wild versions of the pig symbols have the same value as their non-wild counterparts. Landing three, four, or five scatter symbols results in ten free spins in the Bonus Game, Super Bonus Game, or Ultra Bonus Game. Each bonus round has a win multiplier, which begins at x1, x2, or x3 for the Bonus Game, Super Bonus Game, or Ultra Bounce Game. Scatters are only found in the base game. In all three bonus rounds, collecting Moon symbols results in a prize. Collecting three Moon symbols gives you +2 free spins and doubles the win multiplier, while collecting six Moon symbols gives you +2 free spins and doubles the win multiplier once more. 

When winning symbols appear on the reels and form winning combinations, the Tumbling Reels mechanic removes them. Symbols slide from top to bottom, providing another opportunity to win. Tumble sessions finish when no new wins occur.

After tumbles 2, 4, and 6, the red, green, and blue piggy pay symbols transform into Piggy Wilds.

Pig symbols are protected when tumbles generate winners and are deleted. After three piggy symbols are eliminated, protection level one is attained, and after six piggy symbols are removed, protection level two is obtained. Protected symbols lose their level of protection during a tumble rather than being eliminated from the board. When a symbol loses all of its protective layers, it is no longer protected.

Big Bad Wolf is an excellent example of a sequel that strikes the perfect balance of old and new. This acknowledges its elders while also catering to fans of previous games, resulting in a follow-up that does not feel forced, meaningless, or overshadowed by the past.
