15 Stars Ablaze Slot by Playtech

The Hold & Respin here won't start until Coins fill the whole middle reel, reel 3 top to bottom. Once it does, every Coin and symbol on the grid locks in place, you get 3 respins, and each new Coin or symbol that lands resets the counter back to 3. It keeps running until the respins run out or the grid packs full, then the whole board pays at once. Coins carry their own cash values, from 5x up into much heavier multiples of the bet.

Two things swing the totals. A Golden Pot lands mid-feature, sweeps up every Coin on the grid, and multiplies that pile by up to x20, though it leaves the jackpot symbols untouched. And filling all 15 positions with any Coin or symbol pays the Grand outright. The four jackpots run Grand 1000x, Major 100x, Minor 25x, Mini 10x, and apart from that grid-fill Grand they come through a Mystery Star. A plain Mystery reveals a Coin, a cash prize or a Pot; a Mystery Lock reveals one of those and clamps it in place until the feature triggers.

Two dials sit under your control. A chili-meter sets the volatility to Low, Mid or High, trading how often the feature hits against how big the average win runs. And paying an Extra Bet of x2, x3 or x5 the stake shortens the odds of getting in, the only shortcut here since there's no separate buy button. The setting is all heat: red-and-orange flames and shimmering haze behind an ornate gold cabinet with carved Ionic pillars, the Coins themselves big round medallions stamped with laurel wreaths and a central star holding the cash value.

The number in the title just counts the grid, 15 positions here, with a 9 Stars Ablaze squeezed onto a 3x3 and a 20 Stars Ablaze stretched to a 5x4, all three sharing the same coin engine.
