Crown of Secret Slot by Fazi

Three or more genie lamps anywhere on the reels open the bonus, and from there the game stops behaving like a fruit slot. You get a single free spin, but it's a free spin with a guaranteed win, and the lamp count decides how big the symbols on that spin actually are. Land 3 lamps and the first three reels merge into one block of giant symbols while the last two stay locked behind chains. Land 4 and the merge stretches across four reels with only the fifth shut out. Land all 5 and every reel fuses into a single oversized grid, the full MAXGRID, where one matching symbol fills the entire screen.

Before that spin resolves you pick 3 of the lamp symbols, and each one reveals an award: a respin, an x2, or an x3. The respin unlocks one more reel and hands you another free spin, so a run that started at three merged reels can keep extending toward the full board. The x2 doubles the bonus win and the x3 triples it. Each of those feature symbols pays out once, then reverts to an ordinary symbol, so you can't keep milking the same x3. It's a tidy little engine, and the merging reels are what push this to a 15,700x ceiling, well above what the modest base paytable would suggest.

That base game is straightforward fruit-machine stock: a red 7 on top that pays from just two of a kind, golden bells and blue grapes below it, then watermelon and the usual plum, orange, lemon and cherry low tier, all glossy against a deep-green Arabian backdrop strewn with stars and arabesques, gold lamp-shaped rails down each side. The jewelled gold Crown is the wild, and it only turns up on reels 2, 3 and 4, standing in for everything except the lamps. Three mystery progressives, Gold, Diamond and Platinum, tick along the top and can drop on any base spin.

If you'd rather not wait for the lamps, buy bonus sells the feature at three price points that map straight to the merge tiers: 70x your total bet for three merged reels, 170x for four, and 510x for the full five-reel MaxGrid with its giant symbols. Any win, in or out of the bonus, can be sent to a red-or-black gamble that doubles up to a 50,000 cap. It's one of Fazi's more ambitious classic-fruit titles, dressed up with an Aladdin lamp and a reel-merging trick most fruit slots never bother with.
