Jolly Santa Slot by Endorphina

The whole bonus turns on one symbol behaving differently from the rest. In the base game you spin a 3-reel, 5-line classic fruit setup with glossy cherries, plums, lemons, grapes and a watermelon, a flaming red 7 and a BAR up top, and a Wild that fills in for everything except the two coin symbols. Those coins are the point. Gold Coins drop only on reels 1 and 3, each stamped with a cash prize, and Jolly's Coin lands only on reel 2 as the collector. Get all three reels showing a coin at once and the Crazy Xmas Bonus opens.

Here's how the collect actually works, because it's the part worth understanding. The grid becomes a 3x3 board of Gold Coins, Jolly's Coins and empty cells, and the Jolly's Coin on reel 2 sticks for the entire round. After every spin it sweeps up the prize value of each Gold Coin currently on the board and adds those to its running total. So a single Gold Coin worth 10x feeds into that center coin, then the next spin's Gold Coins feed in again, stacking the collector higher each time. Land more than one Jolly's Coin and each of them collects from all the Gold Coins independently. The round runs on attempts, and any coin landing resets them, so a board that keeps producing coins keeps breathing. When it stops, every Jolly's Coin total gets summed and paid.

The coin values run 1x, 2x, 5x, 10x and 15x for regular prizes, then jump to the four jackpot plaques racked down the left rail: MIN at 25x, MID at 50x, MAX at 150x, and ULTRA at a flat 1000x. Those tiers exist only inside the bonus, so the coin trigger is the single path to them. There's a safety net for the near-misses too: if coins land on only one or two reels, Lucky Time can fire at random and drop in the extra coins needed to force the bonus anyway.

No free spins, no buy feature, no ante. Wins outside the bonus can go to the standard Endorphina card gamble, picking a card to beat the dealer and double up to ten times in a row. The look leans into the joke, a pin-up Santa in a red corset and green stockings sprawled across a hoard of gold coins above the reels, gifts and sparklers behind a holly garland spelling out the name, all on a bright party-red background. It's the Christmas cousin of Endorphina's Crown Coins, same reel-2 collector engine, just swapped from fruit-machine neutral into full festive kitsch.
