The wild symbol is a green ring, it can land on reels 2, 3, 4 and 5 and substitute for all the other symbols in the game to help and form winning combinations.
There is no scatter symbol.
The slot features Collapsing Reels. Every time that you land a win, the symbols involved will disappear to allow more symbols to fall from above. Hopefully this will form another win and this way the process can repeat itself indefinitely. Furthermore, each consecutive win fills up a segment of the Green Lantern Power Bar and if you manage at least four consecutive wins, it will trigger one of three bonus features.
If you trigger the Fear Flight Mission, you will receive unlimited free spins with a special stacked wild symbol. During the spins, all the symbols from the previous spin, except the stacked wild, will explode to allow more to fall. The stacked wilds collect at the bottom of the reels throughout the mission and the spins continue until you reach a stacked wild maximum that is determined by how many Power Bar segments are full. If it is full to Charge 1 you receive 5 stacked wilds, Charge 2 allows 6 stacked wilds and Charge 3 allows 8 stacked wilds.
In the Training Center Mission, you receive ten free spins with extra wild symbols. The higher the Power Bar charge the more extra wilds are added to the reels. The wilds have different names and at Charges 1, 2 and 3 they are Grenade Wilds, Missile Wilds and Punch Wilds respectively.
In the Secret Sector Mission, you receive ten free spins with a dynamic multiplier. At the start, you receive a random multiplier and with each consecutive win, the multiplier increases. The higher the Power Bar charge the larger the multipliers you can receive.
The slot is linked to four progressive jackpots and the bonus game can begin after any spin. Once it starts, you are sure to win one of the four jackpots. In the jackpot game, you will see a grid of twenty jackpot symbols. Each time you click on a symbol, it reveals one of four coloured jackpot symbols. Each colour corresponds to one of the jackpots up for grabs and you win a jackpot when you fill up its meter. To win the Mini jackpot you need to find 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 progressive jackpots, there is a top fixed payout of 500x for landing five Green Lantern symbols on the reels, the Guardian or Oa can payout up to 300x, Sinestro can payout up to 150x, and Kilowag and Tomar-Re can both payout up to 75x. A and K can payout up to 60x, Q and J up to 50x, and 9 and 10 up to 40x.
