Ignis Rex Slot by Evoplay

A 5x3 fruit grid wrapped in golden frames and firelight, built around two linked coin mechanics. Locked Coins sit on the reels showing multipliers between 1x and 20x total bet but pay nothing until the bonus triggers. Unlocked Coins, by contrast, pay their face value the moment they appear - a small but steady income stream during the base game.

The Wild is a portrait of the king himself. When it lands, it sticks in place and awards up to three free respins. Additional Wilds that land during those respins also stick and reset the counter, so a lucky streak can fill a significant portion of the grid. The Scatter pays instantly regardless of paylines: one Scatter awards 5x, two award 10x, and three award 100x total bet. Scatters only appear on reels 1, 3, and 5.

Three or more Coins landing on the same row trigger the King's Coins Bonus, a hold-and-win round starting with 3 spins. Regular symbols vanish and only Coins remain. Each new Coin that lands resets the spin count to 3 - and doubles the value of every Coin already on screen. That doubling mechanic is the centrepiece: a grid that fills steadily can push accumulated values well beyond their starting multipliers. The round ends when spins run out or all 15 positions are filled.

The paytable is top-heavy. Five red 7s pay 200x, five Cherries 100x, while the four low fruit symbols cluster between 5x and 10x for a full line. Combined with the 13.41% hit rate and medium-high volatility, base game wins are infrequent but the sticky Wild respins and coin doubling bonus provide the real payout potential up to 2,532x.
