You can rotate from as low as 20p to a spinning game of up to £100. If you collect 3 keys, the next wild animal that appears on the reel becomes a 2 money bag. If you collect 3 more keys (so 6), the new wild animals will become the wild of the 3 golden hens.
Jack and the Beanstalk use the new Walk Wild feature - when the Walking Wild and free spins appear on any of the scrolls in the base game, you'll get re-spin (at no extra cost).
