Gem Miner slot is played on five reels, three rows, and 20 fixed paylines. With 20 paylines, players have many chances to form winning combinations. The payline wins only if the combination is made from the leftmost reel to the right. Also, all wins are according to the paylines and must be made on adjacent reels.
The exciting part of this slot's gameplay is the cascading feature. Every time you land a win, the symbols involved disappear, and the symbols above them will drop down. Then, new symbols will drop in to fill up the vacant positions. This can lead to more wins without spinning. Every time you land a win with a winning cascade, it increases a multiplier. You can get up to a 5x multiplier, which can really kickstart a winning run.
With as low as €0.20, you can start spinning the reels on this video slot. It also offers a maximum bet of €100, so both high rollers and low budget players can look forward to playing this slot.
