Fire Siege Fortress™ has three windows at the bottom of reels two, three, and four. They light up on every spin in the base game and Free Spins and will activate one to three reel modifiers if a Wild symbol lands in one or more windows.

• Wild on reel window two – Archer Attack: Two archer snipers appear from the right and shoot arrows at random positions on the reels, except where a scatter or a wild is present. One to three reel positions will turn wild.
• Wild on reel window three – Dragon’s Breath: A fire-spewing dragon appears from the right and lights up reel three, transforming it into a Wild Reel.
• Wild on reel window four – Trebuchet Assault: A powerful trebuchet will be reeled in from the right, which fires then one or two balls onto random reel positions. The hit positions will turn Wild and the symbol expands one space down to create Giant Wild.

All three Wild modifiers can be triggered in one spin, which would be the exact moment where the maximum win on a single spin for this slot can be hit. It would need a wild symbol landing on all reels in a spin, amounting to a total of five Wilds. If the middle ones each hit the Wild Window and then award the maximum possible extra Wilds, then it would add another eight Wild symbols on to the reels. Three from the Archer Attack, three from the Dragon’s Breath and two from the Trebuchet Assault. Added to the five initial Wilds from the spin, this would lead to a total of 13 Wild symbols spread over the 18 reel positions. Together with premium symbols in the remaining five positions would award the maximum win of 3,456x the bet, equal to 576 times 5OAK dragon symbols, each paying 6x the bet.

When Dragon’s Breath and Trebuchet Assault are activated at the same time, only one Giant Wild will appear on the reels. Wins are evaluated and paid after all modifiers have been applied.
