The bonus game features at the top of the beanstalk, and as such doesn’t use a progression up the stalk, but there is a nicely produced animation you can choose to watch with each entry to the bonus feature. It’s worth watching just the once, if not to just appreciate the amount of work that has gone in to making this gem of a slot machine.
The main bonus feature is a free spins bonus triggered by landing three or more treasure chests in view, this will award 10 free spins. The bonus can be re-triggered and each time offers a further 5 free spins on top of what remains. The free spins bonus uses new reels, and as mentioned previously, takes place in the castle at the top of the beanstalk.
The free spins auto-play until completed, and offer additional bonus features that take place in conjunction with the main bonus. These are progressive Walking Wilds, and offer up a wild symbol that moves from left to right, with each step moving one reel across. The Walking Wilds are wild symbols that pay x3 in the free spins bonus game, they also halt the free spins and use their own re-spins until they have cleared the screen, your remaining free spins will then continue. This allows for some very generous wins, with the bonus games often lasting a lot longer than you would expect from normal free spins features on other slots.
The Walking Wilds are also progressive, with each level of progression triggered from the bonus Key symbol on reel five of the bonus reels. Each level completed with three keys offers a more powerful Wild symbol, with the final level; active after nine keys, a stacked Walking Wild offering immense winning potential. A single Walking Wild is also available on the main base-game, and again offers a free re-spin until it has cleared the screen.
The Jack and the Beanstalk slot machine is an incredibly enjoyable game, with a very generous bonus round. It features a playing percentage of 96.3%, with stakes up to £100 per spin.
