King Richwin Slot by Playtech

The bonus hands you a Collector King who fills four cells and strolls the grid. He arrives at 2x2 when the round triggers, then moves each spin to scoop up Collect Gems and cash Prize symbols, and any prize already sitting behind him gets banked without him needing to reach it. Those gems and prizes carry values from half your bet up to 15x, with the four jackpots tucked into the same pool. It opens with five spins and behaves like a hold and win round, so only the collected total matters. Each set of gems the King grabs grows him a size and adds one, two or three spins to the counter, which means a hot run keeps feeding itself until the spins finally empty and the whole haul pays.

Which coloured gems set the round off decides how it plays, and any mix can be live at once. Pink runs Rich Rows, stretching the board to a taller 5x8 so the King can bloat all the way to 8x5. Green runs Rich Spins, letting an extra spin turn up on a gem or prize instead of a cash figure. Blue runs Rich Multis, dropping a 2x onto Collect Gems and 2x or 3x onto Prize symbols, and a multiplier landing on a Collect Gem makes the King collect that gem as many times over. Fill one of the coloured Gem Piles during normal play and the matching feature fires. Or skip the build entirely: the buy option at 100x forces the round with all three modifiers switched on together. The jackpots sit inside that pool too, Grand at 1,000x the bet, then Major 200x, Minor 50x and Mini 20x, each one banked exactly the way the King banks everything else rather than spun off a separate wheel.

Away from the bonus it's a plain base game across 20 fixed lines, wins reading left to right, with a Wild that stands in for everything except the Scatters and the gem symbols. The look is pure storybook: a white-and-blue turreted castle behind clipped cypress hedges under a cloudless sky, and a round, beaming King in a gold crown, sometimes trotting past on a golden horse. His red-haired Queen, a roast-chicken banquet, a golden herald's bugle trailing a red ribbon and a heaped treasure chest sit at the top of the paytable, with pink, green and blue gems and glossy gold royals under them. Cheerful royal pantomime, nothing grim about it.
