Phoenix Heat Slot by Playtech

The Fire Boost only triggers from reel 1 or reel 5 in the base game, and that single constraint shapes everything else. Land a Fire Boost on either of those outer reels and it sweeps up every Cash Coin sitting anywhere on the 5x4 grid. Drop two Fire Boosts (one on each end) and the collection compounds, each symbol pulling in the same haul independently. The middle three reels never spawn the trigger in the base game, so most spins where Cash Coins do land go unconverted and clear away unpaid. It's a deliberately stingy cash-collect setup built around making the rare trigger feel like an event.

Free Games change the rule. Once you're inside the bonus, Fire Boost can land on any of the five reels and each one sticks for a random 1, 2, 3, 4, 5 or 10 spins, meaning a sticky boost on reel 3 with a ten-spin duration turns every middle-reel Cash Coin into harvestable cash for the rest of the round. The trigger itself is unusual: you don't count scatters, you sum them. Free Game Coins carry +3, +4 or +5 numbers, and the total spins awarded equals whatever those collected coins add up to. Three +5 coins gives 15 spins, a +3 alone gives 3, and the round can run very long or very short depending on what was on screen the moment the Fire Boost dropped.

The Fiery Booster is the upgrade layer that ties it together. Coins occasionally land with a fiery animation, and if a Fire Boost is anywhere on the reels at the same time, every fiery coin gets its value upgraded before collection. In Free Games, a Fiery Fire Boost itself can stretch its sticky duration up to the full 10 spins. There's also a Nudge Feature that occasionally pushes a Fire Boost into view on non-trigger spins, which is the game's quiet pressure-release valve when the boost has been absent for a stretch.

The four-tier jackpot sits on its own trigger entirely. A Diamond symbol plus a Fire Boost anywhere on the reels reveals one of MINI 10x, MINOR 25x, MAJOR 100x or GRAND 500x, chosen at random, and each tier can land multiple times in the same round. With the Extra Bet toggled on, the trigger frequency for Free Games shifts upward at a 1.5x base cost, and the Buy Feature button below it skips the wait entirely if you want to go straight to the bonus.

Visually the reels sit between two ornate stone temple pillars with a sunset desert pagoda silhouette behind them, the grid bordered in red-and-gold filigree, the phoenix logo in flame-licked gold lettering anchoring the centre. Cash Coins display in golden talon holders clutching red and purple gemstones, Free Game Coins glow blue with their numbered values inside, and the Fire Spreader carries a peacock-tail feather that fans out when it lands. The colour palette runs warm crimsons and oranges everywhere except the cool blue numbered coins, which is how your eye learns to spot Free Game triggers across a busy reel before the spin even resolves.
