Jewel Stepper Slot by Blueprint Gaming

Three reels, three rows, five fixed lines, and an entire game built around what happens on the middle reel. The Cash Collect scatter only ever lands on reel 2, and the Cash Prize scatters only ever land on reels 1 and 3. That asymmetric setup is the whole reason Jewel Stepper exists as a mechanic, because when a Collect does land in the centre, it triggers the signature behaviour: on the next spin, the symbol steps down one position. The spin after that, one more. It keeps walking down the reel until it exits the bottom or until a bonus fires, and during every step it sits in view ready to pull in any Cash Prize that lands beside it on reel 1 or reel 3.

The base game is otherwise a flat retro fruit machine. Cherries, lemons, oranges, watermelons and grapes do mid pay duty, 9 through Q cover the low end, and Bell, lucky 7, Star and a sparkling blue diamond climb to the top. Wilds substitute for everything except the two scatters. Land Cash Prize on both reels 1 and 3 while a Cash Collect is parked on reel 2 and the Cash Collect bonus begins.

That bonus is a tight 3-spin reset round. The triggering Collect locks in place. Any new Cash Prize is absorbed into every Collect on screen and the counter resets back to 3. Up to three Collect scatters can stack on reel 2, each banking its own running total, and the round ends when the spins finally run out. Sitting above the reels are four jewel-coin pots labelled Grand, Major, Minor and Mini, with the Grand displayed at 1,000x your stake on a £1 bet.

There is also a random Jewel Strike that can drop enough symbols onto the reels to force the bonus trigger, plus a Power Play mode at 5x stake that strips out the fruit and royals entirely. Only Cash Prize and Cash Collect symbols remain active, the stepping mechanic stays live, and you are paying for nothing except feature frequency. Bright red sparks behind a deep blue reel frame, classic British pub-fruit symbol set, and a clear engine pedigree shared with the Cash Strike Hotstepper line.
