The wild symbol is the batman logo; it can land on reels two, three, four and five and will substitute for all the other symbols, except for the bonus symbol, to help and form winning combinations.
The scatter symbol is a blue ‘Bonus’ symbol on a green background.
The slot features collapsing reels. This means that every time that you land a winning combination, the symbols in it will disappear to allow more to fall from above. Hopefully this will form more wins and the process can then repeat itself indefinitely. As a result, it is possible to land multiple wins from a single spin.
During the base game, The Riddler can add mystery symbols to the reels on any spin. These are then transformed into matching symbols to hopefully form a big win.
The Batman vs The Riddler Bonus Wheel is triggered when the ‘Bonus’ symbol lands on reels one, two and three simultaneously. You then spin the bonus wheel to trigger one of the following features.
- Sticky Wild Free Spins – You win ten free spins during which special sticky wild symbols freeze in place on the reels. They will remain in place and help to form wins until the third wave of any collapsing reels sequence.
- Multiplier Free Spins – You win ten free spins with a multiplier that increases by 1x up to a maximum of 5x on each consecutive collapsing reels win. The multiplier is reset when the wins stop.
- The Riddler Box Bonus – This is a picking game in which you need to select from the 12 boxes displayed until you find three matching values; then click on the next set of boxes to find three matching multipliers that are applied to the win.
The slot also gives you the chance to hit four progressive jackpot prizes. The jackpot game can begin on any spin, regardless of which symbols land, and if it starts, you are guaranteed to win a jackpot! In the game, you will see a grid of twenty jackpot icons and you need to pick them one at a time to reveal different colours. Each colour represents one of the four jackpots and when uncovered it will fill up a segment in the corresponding jackpot’s meter. You win the first jackpot whose meter you fill. The Mini jackpot is won by finding two green icons, the Minor jackpot is won with three blue icons, the Major jackpot is won with four yellow icons and the massive Grand jackpot is won by finding five red icons.
In addition to the jackpots, there is a top fixed payout of 500x for landing five of the Riddler symbols, Batman can payout up to 300x, Robin can payout up to 200x, Commissioner Gordon can payout up to 50x, and the remaining three symbols can all payout up to 20x.
