Steamworks - Gears of Fortune Slot by Peter & Sons

Reel 5 is the trigger for everything. Coin symbols land freely on reels 1 through 4 during base play, but they don't pay anything on their own - they just sit in a counter on the left side of the grid, waiting. Only when the scatter hits reel 5 do those coins get collected, and only then does the 0/20 tracker tick upward. Miss the scatter, and whatever coins appeared that spin are gone. It's a slow accumulation that makes reel 5 the only position you're actually watching.

Fill the counter to 20 and the bonus opens as a respin round on a separate panel. Three respins, resetting each time a new symbol sticks. Coins carry values from x1 up to x20, but the interesting symbols are the specials. Collectors grab every coin value currently on the board and add the total to themselves. Shock Waves bump nearby coins up by +1, +2, +3, +5, or +10 - so a x3 coin sitting next to a +5 Shock Wave becomes x8 before anything else resolves. Four Big Coins act as fixed jackpot prizes: Mini at 50x, Minor at 100x, Major at 200x, Grand at 1000x. Filling every cell on the board awards the Grand outright.

Brass pipes, interlocking gears, and heavy iron chains wrap every edge of the grid in a warm copper-brown steampunk frame. Classic fruit symbols - purple grapes, red cherries, green plums, yellow lemons, orange 7s, blue horseshoes - pop against the dark mechanical backdrop, each one drawn with enough sheen to read clearly through the industrial clutter. Wilds pay the same as the top symbol at 200x for five, and they substitute for everything except the scatter, but there's no expanding or multiplier trick attached to them. No buy bonus either, so the only path into the hold-and-win round is grinding coins twenty at a time.
