Review

It's interesting to see the progression of this game series, with this release following closely in the footsteps of its predecessors. The unique backdrop sets this game apart slightly, and as before, you cannot win anything in the base game. The only goal of the base game is to trigger the Bonus Game, achieved by filling the 4 central positions with bonus symbols.

A special symbol can aid you in this endeavor, and there are several special symbols that will benefit you during the feature. You can customize your spin speed, volatility, and ante bet level from 3 options each, making this game a flexible experience. Filling the Bonus Game grid with bonus symbols awards the 1,000x potential, and you can also win substantial amounts from bonus symbols.

Slot Features

The first consideration when playing is the Chance Level ante bet feature. It’s off by default, and it has 3 settings in addition to off. You can choose to pay 2x, 4x, or 6x more per spin, increasing your Bonus Game chances by the same amount. You can also adjust volatility and game speed using 3 settings.

There are no pay symbols, only bonus symbols, and all wins occur in the Bonus Game. You need 4 bonus symbols in the 4 central positions to trigger the feature, and a special symbol can assist. It remains sticky until the end of the next bonus round, regardless of its position, and awards between 5x and 10x your stake.

The Bonus Game takes place on a 16-position grid, starting with 3 respins. Only blanks and bonus symbols appear during the feature, and new bonus symbols become sticky along with the triggering symbols. This resets the respins each time, and cash bonus symbols offer prizes between 1x and 5x your stake.

You can also land bonus symbols, worth 10x, 20x, and 50x your stake, respectively. The Collector symbol gathers the prize value from all cash and infinity symbols, boosted by a multiplier between x1 and x20. The Mystery Symbol can transform into any bonus symbol except the infinity symbol, and the Jackpot Mystery symbol reveals 1 of the 3 previously mentioned jackpots.

All cash values are totaled when you run out of respins, ending the Bonus Game. Filling all 16 positions with sticky bonus symbols awards the Grand Jackpot worth 1,000x your stake. This is the game’s maximum win, forfeiting all other winnings.

The Bonus Buy menu is available in some regions. It offers 5 options:

• Low volatility - pay 50x to get 3 regular cash symbols, plus 1 special infinity symbol.
• Standard volatility - pay 75x for the same as above, plus a Mystery Symbol.
• High volatility - pay 100x for the same as above, plus an extra special infinity symbol.
• Extreme volatility - pay 150x for 5 special infinity symbols, 1 Mystery Symbol, and 1 Jackpot Mystery symbol.
• Double Extreme volatility - pay 300x for the same as above, plus 1 extra Mystery Symbol.

Review Summary

With each game building on the last, this series continues to evolve. The 4x4 grid is the main difference from the previous game, and the backdrop creates a unique visual presentation.

You only need 4 bonus symbols to trigger the main feature, which is less than the previous installment. You can choose between 3 volatility levels, and the Bonus Game includes familiar elements. The Collector symbol is valuable, offering a potential multiplier boost. The 1,000x potential mirrors the previous game, which is slightly disappointing, but this game is still an enjoyable addition to the series.
