Developers of online slot games are constantly looking for ways to give players more control over their gaming experience. As slot games become more sophisticated, new features are being added to make the gameplay more exciting than simply replenishing credits and pressing the ‘Spin’ button.

Take, for instance, games like Betsoft’s Good Girl Bad Girl. This thrilling online slot game allows players to choose the level of volatility before they begin playing. Additionally, multi-player slots such as Microgaming’s Mermaid Millions enable multiple players to activate bonuses by combining their results.

Bally, a renowned US slot machine manufacturer with decades of experience in the gaming industry, has introduced its latest game, Gem Machine, which offers players the ability to not only select their bets but also which reels to bet on. Furthermore, there are numerous substantial progressive jackpots waiting to be triggered. Let’s delve deeper into the game.

The Player Has Control with Buy-A-Reel

Although initially focusing on land-based game development, Bally Technologies has recently extended its portfolio to include an exciting range of online and mobile slots.

Scientific Games acquired Bally in 2014 in a monumental $5.1 million deal. Now part of the SG Gaming group alongside established developers like WMS and Barcrest, SG/Bally has introduced some innovative games since the acquisition, with the Gem Machine video slot being a promising addition.

Gem Machine is played on a standard 5-reel setup, but with a significant distinction from typical 5-reel games: each reel can be independently wagered on. The reels are numbered 1 to 5, allowing players to choose where to place their bets by selecting each reel number individually. Payouts are determined based on the symbols appearing on the active reels. Consequently, the more reels you bet on, the higher your chances of winning money.

This ‘Buy-A-Reel’ concept is likely to appeal to players. Could we see this feature adopted by other slot developers in the near future? Its adoption may hinge on the frequency of wins and the payout ratios. The game boasts an RTP of 95% when betting on one reel, which increases to just over 97% when betting on all five reels, showcasing a noticeable difference.

Win up to 1000x Your Wager with the Gem Symbols

Unlike other gem-themed slots, Gem Machine offers a unique gameplay experience. Rather than requiring matching symbols on horizontal paylines, rewards are granted for landing specific symbols anywhere on the reels. For instance, hitting one blue gem awards 1x your bet, with 2x for two gems and 5x for three.

The rewards significantly escalate with green gems, offering 10x, 20x, and 50x your wager for landing one, two, or three symbols, respectively, on your chosen reels. Yellow gems offer even more substantial payouts, granting 100x for one symbol, 500x for two symbols, and a whopping 1000x for three symbols.

Players have a diverse range of betting options in the Gem Machine video slot. The minimum bet is 0.05 per reel, while the maximum wager is set at 30.00 per reel.

Aim for the Colorful Jackpots for Lucrative Wins

Aside from the ability to select each colored reel independently, players can also pursue five distinct progressive jackpots. By landing jackpot symbols on the reels, players secure the corresponding displayed prize. The game features five progressive jackpots categorized as Mini (Reel 1), Minor (Reel 2), Major (Reel 3), Mega (Reel 4), and Grand (Reel 5).

Each jackpot symbol corresponds to a specific reel, necessitating players to activate the relevant reels to compete for the jackpot prize. The jackpot payouts range from 100x your total bet for the Mini jackpot to a substantial 5000x bet for the Grand jackpot symbol.

Free spins provide slot enthusiasts with opportunities to boost their winnings. The free Gem Machine slot offers extra gameplay rounds by landing ‘Free Spins’ symbols, each displaying various multipliers (1x, 3x, or 5x) and can appear on any reel. Players receive the number of bonus free games indicated on the symbol.

Select Your Gameplay Style and Strive for the Jackpot

Slot developers continually strive to deliver fresh experiences to players, and with the Buy-A-Reel feature in Gem Machine, Bally might have crafted a winning formula. The addition of progressive jackpots further enhances the excitement surrounding Gem Machine.

However, the process of selecting which, and how many reels to wager on involves some trial and error. Most reel positions in Gem Machine are vacant, suggesting that opting for more reels could increase the likelihood of landing cash prizes.

Experience the free Gem Machine slot today. With a rich selection of classic slots in its collection, Bally invites players to try out this new release and determine its appeal in terms of entertainment and rewards.
