King Richwin is a 5-reel, 20-line royal-themed slot developed by Playtech, set in the opulent grounds of a jolly monarch's castle where treasure chests, golden horses, and shimmering gems overflow from every corner. The game blends classic line-pays with a colourful gem-collection mechanic, four progressive jackpot tiers, and a signature King Richwin Feature driven by three distinct gem modifiers. With a growing Collector King, cascading prizes, and a Buy Bonus option, this cheerful kingdom delivers regal entertainment layered with generous feature depth for players seeking a lively slot experience.
The Kingdom of Endless Riches
Beyond the pristine white towers and blue-tiled spires of a fairy-tale castle lives a portly, moustachioed king whose greatest joy is celebrating abundance. His halls brim with roasted feasts, jewelled crowns, and chests spilling with glittering coins, while his faithful golden steed waits proudly at the palace gates.
This is a realm where prosperity is a way of life. The queen shares the king's beaming warmth, and the manicured hedgerows and cypress-lined pathways lead visitors ever deeper toward the heart of the treasury.
Sparkling gems in pink, green, and blue are the true lifeblood of this kingdom, each one carrying the promise of a different royal reward. As they gather in glowing piles, the merry king himself grows ever larger, sweeping across his domain to gather every last jewel and celebrate his ever-expanding fortune.
Wild and Scatter Symbols
The Wild symbol substitutes for all symbols except the Scatter and the Gem symbols, helping to complete winning combinations across the reels. The Scatter is represented by the King himself, and landing three or more Scatters in any position triggers the King Richwin Feature along with one or more feature modifiers.
Gem Symbols and Gems Piles
The Pink, Green, and Blue Gem symbols are central to the game. When a Gem lands in the main game, it is deposited into the Gems Pile of the matching colour. Once one or more Gems are deposited, there is a chance the Gems Pile will trigger, awarding the King Richwin Feature with the corresponding modifier. The Pink Gem can trigger the Rich Rows bonus, the Green Gem the Rich Spins bonus, and the Blue Gem the Rich Multis bonus.
The King Richwin Feature
The feature begins with 5 spins and, unless modified, is played on 5 reels, 5 rows high. At the start, the Collector King appears in a 2x2 size. The Collector King moves to collect Collect Gems and any prizes displayed on them, while Prize symbols landing behind the King are also collected. As Gems are gathered, the King grows in size and extra spins are awarded, expanding up to a 5x5 King in the standard feature. When all spins are used, the collected prize amount is awarded.
Gem Modifiers
The Pink Gem Modifier activates the Rich Rows bonus, played on 5 reels and 8 rows high, allowing the King to grow all the way to an 8x5 size as Gems are collected. The Green Gem Modifier powers the Rich Spins bonus, where an extra spin may appear on Collect Gem or Prize symbols instead of a cash prize. The Blue Gem Modifier drives the Rich Multis bonus, applying 2x multipliers to Collect Gems and 2x or 3x multipliers to Prize symbols.
Progressive Jackpots
Four jackpot tiers — Grand, Major, Minor, and Mini — sit above the reels. Prize values landing on Collect Gem and Prize symbols range across multiples of the total bet and can include the Mini, Minor, Major, and Grand tiers, offering escalating rewards during the King Richwin Feature.
Buy Bonus
Where enabled, the Buy Bonus option lets players trigger the King Richwin Feature directly with the Pink, Green, and Blue Gem Modifiers all activated at once. Simply select the Buy Bonus bet level and confirm the purchase to launch the feature.
