Gold n Gems slot review
The Gold n Gems online slot from Concept Gaming offers a distinctive format, with 5-reels or a single reel available. Bonus trails and 3-tired bonus rounds add variety as the reels spin.
Theme and story line
Mining gives the Gold n Gems video slot a familiar underground setting. The action takes place deep in a mine, where the search is for gems as well as gold, silver, and bronze.
Graphics, sounds, and animations
Gold n Gems delivers impressive graphics and animations on both mobile and desktop. Its symbols, backdrop, and interface are presented to a high standard, while the reels spin smoothly without lag. The spinning audio is fairly generic, although the soundtrack is decent rather than spectacular.

Gameplay
In its GCCans review, Evan Carrington presents Gold n Gems as a slot with two distinct ways to play rather than a single standard layout. Players can choose a 5x3 reel format with 20 fixed paylines, where winning combinations are built from left to right and require 3 or more matching symbols. The alternative is a single-reel mode, in which a win comes from finding 1 to 3 matching symbols.
The symbol sets are shared between both modes, except for the Mask symbols in the one-reel game, which reward nothing. The other symbols remain the same, but the number required to make a winning combination changes between the formats.
Payouts for a 5-Symbol combination (or 3 symbols in 1-reel mode) are listed below:
- Gold Bars: 250x
- Silver Bars: 25x
- Bronze Bars: 10x
- Green Lantern: 4x
- Orange Lantern: 3x
- Blue Lantern: 1.50x
Bonuses and free spins
- Feature Trails: In the base game for either mode, collecting gems or golden nuggets builds the corresponding trail beside the left or right side of the reels. Wins using either symbol advance those trails towards normal, super, or mega free spins/gold rush. The bonus may be accepted at any point: take the normal level or continue collecting until a more advanced round is unlocked.
- Free Spins: Completing the Gems trail awards 10 free spins in each of the normal, super, and mega rounds. The three levels differ in potential payout, which rises from one stage to the next, leaving the mega round with the greatest potential.
- Gold Rush: Completing the gold trail opens the same normal, super, and mega levels of the gold rush bonus. This feature removes valued boxes and then presents an offer for all values still available. You may accept that offer or keep removing boxes in the hope of finding one with a higher value.
- Bonus Wheel: Landing 5 bonus symbols, or 3 in the 1-reel game, anywhere in view triggers the bonus wheel. It can then award the normal, super, or mega free spins or gold rush bonus rounds.
Bet sizes, RTP, and variance

Conclusion
Evan Carrington's original review is positive about the Gold n Gems slot's presentation and play, while noting the potential for strong payouts. Its distinctive bonus features may be the main attraction, alongside the choice between 5-reels and 1-reel play.
