About Gemstone Jackpot Slot

Gems were among the hottest theme in the retro age of slot games, and they are commonly used today to relive the era. Gemstone Jackpot slot is among the slots that reflect this past era. The set is a top-drawer selection created by GreenTube and distributed by the software provider Novomatic.

Gemstone Jackpot slot machine was released in August of 2014, but its design does not reflect the modern era. Instead, the slot captures some of the popular features associated with classic slots from the use of bright colours for the gems and realistic but straightforward imaging. The play table includes five black reels spread out against a glowing blue backdrop. The golden outlines on the columns add a luxurious feel to the grid and complement the glittery gems that sit on the screen.

Gemstone Jackpot Gameplay

Gemstone Jackpot slot machine is consistent with the usual playing procedure, starting with the selection of bets between 40 and 10,000 coins. Such a wide betting limit accommodates both small and big spenders. The gameplay procedure is conducted using two buttons placed to the right of the grid. 

The MENU button opens a second page where punters can adjust coins or assess the winnings they stand to collect if lady luck smiles their way. The second button is a white-circular arrow that functions as the spin button. It also supports autoplay, which is activated when it is held down. Three more fields are included at the bottom to provide information on the bet amount, available balance, and last payout.

The wins in Gemstone Jackpot slots cannot be influenced and are awarded randomly, but players can use some tips to improve the gameplay. They include:

  • Playing Gemstone Jackpot online slot using bonuses and promotions granted in casinos online.
  • Accessing the slot in legitimate casinos that assure fairness and safety in their games.
  • Using the demo slot version to assess the game’s basics and the gameplay procedure.
  • Gambling the highest amount possible to collect the big rewards for symbol combinations.

Slot Winnings

Gemstone Jackpot online free slot offers payouts to gamblers depending on the symbols that appear with each spin. The appearance of three to five of the same symbols on an active payline triggers a win. All the symbols are gems. The combos have to be from left to right, and each symbol offers different payout values. The payouts also depend on the placed wager. Here is a Gemstone Jackpot RTP slot review of the winnings when 10,000 credits are used:

Icon Payouts for Three For Four For Five
Brown gem 2,000 5,000 10,000
Purple gem 2,000 5,000 20,000
Yellow gem 2,000 5,000 30,000
Blue gem 2,000 5,000 40,000
Green gem 5,000 10,000 50,000
Red gem 10,000 20,000 100,000
Diamond 40,000 80,000 500,000


The diamond is the most valuable character in Gemstone Jackpot free play slot machines, which makes it the rarest to appear. This payout and all others are the same in the free and real money versions of the game. The only difference is the ability to withdraw the wins when playing for real money.

Extra Features

Gemstone Jackpot slot game may be based on a classic theme, but it does not skip the inclusion of bonuses. The incentives featured in the game are popular with many other Novomatic slots. They include:


  • Gamble feature


Nearly all Novomatic slots have a gamble game, including Gemstone Jackpot demo and cash pokies. This round activates after any win. Gamblers have to either enable it or collect the gains and continue with the base game. When triggered, the set presents a down-facing card with the words RED and BLACK on each side. Punters are required to guess the card colour for a chance to win double the payout amount. Players can guess multiple times to double the amount that came before as long as the right colour is chosen each time. The wrong answer takes away the round winnings as well as the amount used to trigger the bonus. The gamble feature does not activate when spinning the grid using autoplay.


  • Lock and Spin


Gemstone Jackpot slot online does not include the popular wilds, scatters, and free spins. However, the Lock and Spin bonus compensate for this lack of and activates after any winning combination is created. The symbols used in the combo are locked in place before the rest of the grid is sent on a respin. No charges are applied to the bonus round. If the extra spin improves the locked combination, then another respin is awarded with the new icons also locked in place. The respins continue until no more symbols appear to enhance the triggering combinations. If new combinations are formed without adding to the previous ones, then winnings are awarded, and the base game continues. The round also stops when the entire grid is filled with the same character, and the payouts for each are as so:

Icon Payouts
Brown gem 100,000
Purple gem 200,000
Yellow gem 300,000
Blue gem 400,000
Green gem 500,000
Red gem 1,000,000
Diamond 5,000,000

Gemstone Jackpot casino slot online offers one of the highest fixed prizes among online slot. The acceptance of high-risk bets supports such huge winnings. These winning values only apply when the most significant wager of 10,000 credits is used.

RTP Rate

Gemstone Jackpot casino game features an average RTP percentage of 95.08%. This rate gives a hypothetical projection of the winnings that can be expected over the long run. These odds are accompanied by low to medium variance. This swaying volatility means the game is likely to award small and frequent winnings or average amounts in moderate instances. These metrics cannot be used to tell the game winnings accurately, but they indicate the set’s inclination to offer decent winnings.


The Gemstone Jackpot game does not visually stand out from other modern remakes of gem-inspired slot machines. However, it packs a lot of firepower with high payouts of up to 5,000,000 credits. The complimenting bonuses that can drive up winning chances also make the casino game worth a shot.
