4 Mine Carts by 3 Oaks Gaming on 1xBet
4 Mine Carts is a 3 Oaks Gaming slot built on a 5x3 grid with 25 lines. The developer lists its release month as November 2026. Its centrepiece is a Hold & Win mechanic driven by four mining carts that sit above the reels. Access can vary by region and account, so check your own lobby.
What the Four Carts Do
Four mining carts roll and rattle above the reels. The developer describes them as progressive pots, each waiting to be filled with gold and gems. Filling one or more carts triggers the Hold & Win bonus game. The round begins with a random mix of one to four bonus features, and each feature is linked to its own pot.
Because the starting mix is random, the number of active mechanics is not fixed. The developer states players can trigger up to four simultaneous bonus features during play. That randomness is the key structural fact about the game's main round.

The Hold & Win Round and Its Four Features
Once the round begins, players can land bonus symbols carrying various cash values. Fixed Mini, Minor and Major jackpot symbols can also appear. The four pot features each change how the respins behave, and the starting set is randomly drawn.
Expand can add up to three extra rows to the reels. Unlocking all three and filling all 30 cells awards the Royal Jackpot of x3,000. Covering all 15 spaces of the standard grid awards the Grand Jackpot of x1,000.
- Expand — adds up to three extra rows to the reels.
- Power — drops in Power symbols that activate the Power bonus game after the main bonus game ends.
- Collect — unlocks Collect symbols that gather all current values on the screen.
- Multi — adds multipliers of up to x5 to random symbols.
Under Multi, if another multiplier lands on the same spot, the two values multiply together. The Power feature extends play after the main round finishes.
Inside the Power Bonus Game
At this point, the respin action shifts to a wheel-shaped grid. Filling all six spots triggers a multiplier of up to x10. This is a separate stage that follows the main Hold & Win round rather than replacing it.

| Super Bonus Game | All four mechanics fully active |
The buy menus sit inside the game client. Prices and any account restrictions are shown there rather than published as a fixed figure. Take the displayed terms as the authoritative version for your session.
How the Demo Controls Work
The 3 Oaks Gaming demo runs the verified build without a stake. On a desktop layout you will typically see a spin button, a bet selector, an information panel and an autoplay control. The info panel is where the symbol pays and the full rules text live, so open it before reading any pot as guaranteed.
The bonus game state is shown on screen as the carts fill. Respin counts and active features appear within the round itself. The demo mirrors these mechanics, which makes it a fair way to see how often carts fill without committing money.
For a real-money session, the operator's own game page carries the live configuration. Provider specification is not the selected configuration of every 1xBet account, so a missing title in one lobby does not mean it is absent everywhere.
