3 Carts of Gold: Hold and Win

3 Carts of Gold: Hold and Win by Playson is a video slot set inside a gleaming gold mine, with a 5-reel, 3-row layout and 25 fixed paylines. The theme brings a cheerful gold digger, treasure-laden carts, and colourful gems into sharp, immersive visuals. It includes a Free Spins feature: landing three Scatter symbols triggers 8 free spins, and during Free Spins the Wild symbol doubles the win of any payline it participates in. Free Spins can be retriggered by getting three Scatters again.

The core of the action is the Hold and Win Bonus Game, which is activated by landing six or more Bonus symbols (or combining Bonus symbols with gem symbols). In that feature you also get respins and the chance to earn jackpots. Above the reels sit three carts—Boost, Mystery, and Collect—each tied to a different coloured gem. The Boost Cart (green gems) adds multiplier values to all visible symbols, the Mystery Cart (red gems) delivers random prizes, and the Collect Cart (blue gems) gathers all symbol values across the reels into a total.

There is also a Rainbow Gem mechanic during the Bonus Game: when a Rainbow Gem lands it transforms into green, red, or blue and either activates an additional cart feature or enhances the active one by adding another symbol. Four fixed jackpots are available in the Bonus Game: Mini, Minor, Major, and Grand (the Grand Jackpot is awarded for filling all bonus cells on the reel-grid). Players can also use a Buy Bonus option to enter the Hold and Win Bonus Game directly.

You can try it for free in demo mode or play it for real money.
