1942: Sky Warrior Slot Machine

Propellers whir behind the reels, and the spins are accompanied by a dramatic soundtrack worthy of a film epic. The playing card insignia on the grid have been redesigned to resemble uniform badges, and the characters now include four male pilots and a female, clearly bringing the game up to date.

The reels are positioned in front of a plane in flight, and they contain four male and one female pilot symbols. You also obtain embellished royals, and wilds in a win can either increase symbol values or remove all instances of a symbol. These changes are permanent in the bonus round, which is when you're most likely to get big prizes. The theme makes this one worth a spin or two, but it's not for those looking for big wins.

The star wild can replace any of the conventional symbols, and winning wilds will activate a feature. The bonus you receive is determined by the paying symbol that triggered your win. In a single spin, up to two wilds can land.

If wild symbols form a winline alongside lower-paying symbols, the winning lower-value icons will depart from the reels, and other symbols will appear to take their place.

If wilds form a winline with higher-value symbols, these icons will be enhanced, as previously stated in this slot review. If a win includes both higher- and lower-value icons, the higher-value symbols will be updated, while the lower-paying icons will disappear. 

Land three of the ace scatters on the first, third, and fifth reels to earn 10 free spins. During these bonus games, you will receive a wild icon with each spin, and the special features will last throughout the round. Land three more scatters on the same reels as you play to receive five extra bonus spins and keep any bonus feature active.
