Online slot developers have realised a good number of players like to be able to influence a game beyond simply choosing how much to bet per spin. They responded in different ways, most frequently allowing one to control the game’s volatility by, for example, choosing from multiple free spins bonus rounds. Bally found another way to put the player in control. Their Gem Machine is a 5-reel video slot which lets you pick reels you wish to bet on, at the same time offering an opportunity to score multiple jackpots.
Gem Machine Basic Gameplay
Reel area is designed like a machine with 5 transparent pipes plugged in at the bottom. When you press the corresponding reel number on top, the pipe will fill up with coloured fluid, indicating the reel is being wagered on. You’re free to choose 1, 2, 3, 4 or all 5 reels and bet between $0.05 and $30 per reel, or as little as $0.25 (with all reels active) and as much as $150 per spin. Do note that reels have to be selected in sequence, meaning that you can wager only on reel 1, but if you wish to activate the third reel, first two also need to be in play.
Prizes are paid for a single, double and triple appearance of yellow, blue and green gems, no matter where they turn up. It may sound strange, but you’ll see why as soon as you start playing. A number of positions deliver blank slots rather than game icons and you’ll get multiple spins without any gems visible. That means getting 3 identical ones is a success, especially when they are the most valuable yellow ones.
Gem Machine Bonus Round
Landing Free Spins symbols in any position triggers the bonus round. Each of these symbols will display a multiplier of x1, x3 or x5 and award the number of free games indicated on the symbol. Players additionally get to claim 5 different jackpots – Mini, Minor, Major, Mega and Grand. Each is confined to its dedicated reel and betting only on the first reel will give you access to the smallest one. Each additional reel in play upgrades the jackpot.
Gem Machine Win Potential
In this game, the theoretical return to player changes depending on the number of reels one is betting on and ranges between 95% (a single reel) and 97% (5 reels) – not a small difference! Yellow gem is the highest paying symbol which can win you up to 1,000x your bet or a maximum of $150,000 if you’re wagering the highest possible amount. Putting your money on all 5 reels gives you an opportunity to score Grand Jackpot which pays 5,000x your bet per reel and can also win you as much as $150,000 in a single spin.
Gem Machine is a very unique video slot unlike any you may have seen before. Many will appreciate the developer’s creativity and the level of control the game offers, along with high payouts claimable in different ways. Betting range has been set to make the slot accessible to a wide audience and yet still appealing enough to those with bigger bankrolls.
