Golden Crown Max Booster Slot by Fazi

This is the biggest board in the Golden Crown Booster line. Where the rest of the family runs a tight 5x3, this one stretches to four rows deep and threads 40 fixed lines through it, which changes how the headline feature pays. That feature is the jewelled royal crown. It only lands on the three middle reels, and when it does it stretches to fill the entire reel, all four rows, and stands in for everything except the two star scatters. On a four-row reel that single expanding wild touches a huge slice of the 40 lines at once, so one crown on reel three can light up combinations in every direction. Catch crowns on reels two, three and four together and most of the screen is wild.

You don't have to wait around for one, either. The Wild Booster toggle sits on the left, and switching it on guarantees an expanding crown on the very next spin. It stays armed until you turn it back off, at 7x your total bet per spin, which is a steep ask, the priciest Booster in the line by a fair margin. Your line wins still settle on the base stake, so the premium only buys the crown, not bigger payouts on the hits it makes.

The symbol set is straight off an old fruit machine: glossy red sevens, golden bells, oranges, cherries, sliced watermelons, blue grapes and purple plums, all glowing against an opulent gold background patterned with fleur-de-lis. The red 7 tops the regular table and pays from just two of a kind, climbing to 125x for five. Two scatters split the work. A blue star pays from anywhere on the grid and is the high earner at 100x for five, while a red star only counts on reels one, three and five, worth 20x for three.

Running above the reels are three mystery progressive jackpots, Gold, Diamond and Platinum, each fed by a slice of every bet and dropped at a hidden random point, with bigger stakes shortening the odds. There's no bonus round and no free spins anywhere, the crown and the jackpots are the whole show. After any win you can run the red-or-black double-up, pushing until you miss or hit the 50,000 cap.
