The When Pigs Fly slot machine is positioned on a rocket launch pad, with the pig astronauts and rocket ready to blast off as soon as the bonus round is activated. One of the pig astronauts is positioned to the right of the Re-spin counter and will perform humorous animations as the Re-spins advance. Since he will go into space if the reels generate six consecutive wins, he becomes happier with each victory. Low-paying symbols are 10's through A's, and medium-paying symbols include 7's, helmets, and BAR. Two astronaut pigs and the "When Pigs Fly" logo are the top icons. The word "wild" is presented in a piggy pink colour. There are no scatter symbols, as the bonus round is triggered after five consecutive wins.
The countdown to the Free Spins begins with six spins. The Re-Spin feature is activated and the number of spins is reduced to 5. The pig astronaut is also getting excited about the potential space launch. At each winning Re-Spin, the number of pay lines and reel positions increases, and the arrangement of the slot machine changes from 1 – 3 – 5 – 3 – 1 to 5 – 5 – 5 – 5 – 5 – 5. The number of paylines increases concurrently from 45 to 135, 405, 675, 1,125, 1,875, 3,125. If the reels re-spin successfully five times and the slot pattern reaches its maximum size, the Free Spins are launched.
The notion of expanding reels on each Re-spin up to a maximum of 3,125 pay lines and the stacked symbols have the potential to result in enormous and gigantic payouts. The top payout is close to 1,000x the wager.
