Burning Coins 40 Slot by Endorphina

Three colour-coded coins do all the heavy lifting. Blue, red and green, each one a flaming disc stamped with a fire emblem and resting on a heap of gold, sit in a row above the reels. During the base game, matching-colour Token symbols drop onto the grid, landing on top of other symbols, and any Token can randomly light up its coin. When it does, the coin fires off a bonus, then the Token flies away to uncover whatever it was sitting on, which can still complete a line. So a Token is never dead weight.

What makes the round worth chasing is that the three coins trigger three different bonuses, and several can light up on the same spin. Blue runs the Hot Hold Collector game, red the Hot Hold Extended game, green the Hot Hold Payer game. Activate two or three coins together and the variants combine, which gives you seven possible bonus setups in total: Collector alone, Extended plus Payer, all three at once, and the mixes in between.

Every variant is a respin round on a grid of special symbols and empty cells. Bonus symbols land showing a cash prize worth your total bet times a multiplier (up to x25), they stick, empty cells respin, and the round ends when respins run out or the board fills. The Collector symbol sweeps the grid and adds up every Bonus value on it; the Payer adds its own value to all Bonus symbols, then becomes one itself; the Extended variant plays on a taller stepped board of five uneven columns (a six-cell centre, fives beside it, fours outside), where filling a column pays a guaranteed jackpot by height: 50x for a four, 200x for a five, 500x for the centre six. Collecting special symbols across that board feeds the Ultra jackpot, 1,000x at twenty and 2,000x at twenty-four.

If you don't want to wait on a Token cooperating, the Bonus POP button to the left of the reels buys a Hot Hold round straight away, opening with a single base spin that drops one to three Tokens for you. Cost scales with your stake, and anything Bonus POP pays can't be sent to the card gamble. That gamble is the usual Endorphina draw: pick one of four face-down cards to beat the dealer, double up to ten times, joker beats everything and the dealer never gets one. A Lucky Time helper can also spawn symbols to spring a bonus on its own.

The reels are a classic fruit set turned up to a blaze, glossy cartoon cherries, lemons, watermelon, grapes and plums next to a gold star, a flaming red Seven and a gold Wild that can land stacked, all wrapped in flames against a smouldering red-and-black backdrop. The Wild fills in for everything except the Tokens and the bonus symbols. It looks like a simple fruit machine until those coins start catching, and the Collector sweeping a full grid is where it stops being simple.
