Ace Invaders is a three line video poker game produced by International Gaming Technology. The game plays like other multi line video poker games except the bottom line is a Bonus Poker game, while the top two lines are both stud poker based games. The pay schedule for the Bonus Poker game on the bottom line offers a greater than 200% payout percentage (if one plays all three lines), but this is compensated for by the lower payout percentage on the stud poker games on the top two lines.Another feature unique to the Ace Invaders game is the gameplay. The bottom line is dealt and played as a draw poker hand, just like in a standard Jacks or Better game, and the player chooses which cards to keep and discard. Then the game deals the replacement cards, but unlike other video poker games, Ace Invaders doesn’t pay immediately. First the game checks the top line for a paying combination, then pays out for that. Then, if any of the cards in the top line are aces or would help create a royal flush in the second line, they drop down and become part of the hand on the second line. This process repeats itself on the second line, paying out, then checking to see if the cards would help complete a royal flush on the first line, and then drops those cards down again before finally paying out on the first line.
