Developer 3 Jewel Crowns is a three-reel slot from 3 Oaks Gaming, released in June 2025. The game uses five paylines and a betting range from 0.05 to 30. Its design combines a classic slot layout with modern features centred on three Crown symbols.
Wild symbols can appear with x2 or x5 multipliers and help complete winning combinations. Filling the Green, Red and Blue Crown Metres with matching Crown symbols triggers seven free spins. During this round, the metres unlock additional features, including extra spins, a jackpot feature with Minor, Major and Grand fixed prizes, and a double reels feature that activates a second game board.
Crown symbols landing during the free spins round can raise jackpot values by the current bet up to set limits. The Minor jackpot can increase from x25 to x50, the Major from x100 to x250, and the Grand from x1,000 to x5,000. A demo version is available to play for free and practice before playing for real money.
