Ignis Rex Slot by Evoplay

Most hold-and-win triggers ask for symbols anywhere on the grid. This one needs three Coins on the same row - a tighter condition on a 5x3 layout with only 10 paylines. Once triggered, the King's Coins Bonus clears all regular symbols and starts a 3-spin countdown. Each new Coin resets that counter back to 3 and doubles every Coin already sitting on screen. So a Coin worth 2x becomes 4x, then 8x, then 16x if three more land in succession. Filling all 15 positions is the ceiling.

Two types of Coins show up during normal play. Unlocked ones pay their multiplier (1x to 20x) on the spot. Locked ones display a value but sit behind a chain-and-padlock graphic, collecting dust until the bonus round frees them. That split creates an odd tension - you want Locked Coins to accumulate on screen because they feed the bonus, but they give you nothing until it fires.

The king portrait Wild sticks wherever it lands and triggers up to three respins. More Wilds during those respins stick too and reset the counter, so a cluster can build across multiple positions. Scatters are restricted to reels 1, 3, and 5 and pay flat amounts on contact - 5x for one, 10x for two, 100x for three - independent of paylines.

Warm reds and deep burgundy dominate the backdrop, with floating embers and gold-trimmed fruit symbols giving it a regal spin on the classic fruit machine look. The red crystalline 7 is the top-paying regular symbol at 200x for five, while the four lower fruits (lemon, grape, plum, and the 10 card) sit between 5x and 10x. No buy bonus, no ante bet - just the sticky Wilds and the coin doubling bonus carrying the weight.
