How Megaways Jack plays
Reel heights change on every spin, so the number of ways moves up to 117,649. Wins are paid for matching symbols on adjacent reels from the left, then the winning symbols disappear and new ones drop in for a possible chain of wins. Jack himself is the top symbol, joined by the giant, Jack’s mother, the golden goose and the cow, with card royals 9 to A as the lower symbols. A wild can land on reels 2 to 6 and stands in for the regular symbols.
- Magic beans: beans can land during the cascades, and each one turns one to three leaves of the beanstalk golden.
- The golden harp: the harp can appear at random and award extra wilds, a 5x multiplier, extra golden leaves or a respin.
Beans land during the cascades, so a longer chain of wins gives more chances to grow the beanstalk.
The beanstalk free spins
Turn eight or more leaves golden and the free spins start. The height reached decides the round:
- 8 or 9 leaves: eight or nine free spins.
- 10 or 11 leaves: ten or eleven free spins, with the win multiplier starting at 2x.
- 12 or 13 leaves: twelve free spins, with the multiplier starting at 3x.
During the round the multiplier has no upper limit and goes up by one with each cascade. A long run of tumbles can also add extra spins, and the harp keeps appearing with its wilds, spins and multiplier boosts. That climbing multiplier is what sets the game apart: the base game builds the beanstalk, and the round can keep building on it.
