Crown Coins Slot by Endorphina

The collector logic is what separates this from the usual coin-grab. Two coin types matter. Gold Coins drop on the outer two reels carrying a cash value, and a single Royal Coin lands only on the middle reel as the collector. Get coins filling all three reels at once and the Royal Treasury Bonus Game opens, the whole panel turning into a 3x3 board of coins and empty patterned cells. You start with three attempts. Each spin spends one, but any coin landing snaps the counter straight back to three, and only the reels still holding gold coins or empties keep spinning.

Here's the part to watch. The Royal Coin sticks in the centre for the entire round, and after every spin it soaks up the prize of every Gold Coin currently on the board, building higher and higher as more golds arrive. If more than one Royal Coin is in play, each of them collects from all the golds independently. When your attempts run dry, every Royal Coin total is added together and paid. So the round isn't about one big symbol landing, it's about keeping golds feeding a sticky centre that never stops counting.

The prizes baked into those coins run from small 1x and 2x hits up through 5x, 10x and 15x, then jump into fixed jackpot tiers: 25x for MIN, 50x for MID, 150x for MAX, and 1000x at ULTRA, the four plaques stacked down the left rail. Separate from those, a network Progressive Mystery Jackpot can drop at random in three levels, GRAND, MAJOR and MINOR, with higher bets improving the draw odds. There's also a Lucky Time quirk worth knowing: when coins land on only one or two reels and fall short of the trigger, the game can randomly conjure the extras needed to start the bonus anyway.

Base play is plain by comparison. A standard Wild substitutes for everything except the two coin types, lines pay left to right, and winning fruit ignites in flames against the white reel strips. The look is unapologetically regal: glossy purple plums, red cherries, lemons and grapes, golden bells and a red lucky 7, all sitting in a heavy gold border on a deep crimson background, a small crown and a spill of coins tucked over the logo. It's a fruit machine wearing a king's robe. Any win can be pushed into a card gamble, double or nothing up to ten times in a row, though jackpot wins are locked out of that and there's no buy option to skip ahead to the treasury round.
