The Wild Respins feature of Anaconda Wild II is where the game really comes to life. The feature is triggered when 2, 3, 4, 5 or 6 Special Wilds land on the reels at the same time. Once triggered, the Special Wilds will expand to cover the whole reel, and players receive one free respin. During this respin, all regular symbols are removed from the reels and replaced with empty positions or one of the two types of Wilds. Any new Wilds that land will expand and award additional respins. For every respin, the game multiplier increases by one, with no limit on how high it can go. If any new Special Wilds land, they are locked in place, and the respins continue until no new Wilds land.

Another exciting feature in Anaconda Wild II is the Cascade feature. Whenever a winning combination is formed, the symbols involved in the win will disappear, and new symbols will cascade down to take their place. This potentially creates more winning combinations, and the feature continues as long as new wins are formed.

There's also a Free Spins feature, triggered when 3 or more Scatter symbols land anywhere on the reels. Players will receive 10, 12 or 25 free spins, depending on the number of Scatters that triggered the feature. During free spins, the Wild Respins feature can be triggered as well, and the game multiplier starts at 2 instead of 1. Free spins can be re-triggered by landing more Scatter symbols, with no limit on how many times this can happen.

Finally, Anaconda Wild II also comes with a Buy Feature option. For players who can't wait to trigger the bonus features naturally, this option allows them to buy their way into the Wild Respins or Free Spins features. The cost of buying the feature depends on the potential payout, and the calculations are displayed on-screen.

Overall, Anaconda Wild II is a well-designed and exciting slot game that takes players on an adventure to uncover Mayan treasures. With its impressive potential payouts, high variance and multiple bonus features, this game is sure to keep players entertained for hours on end.
