Mine Defender is a space-themed slot from ELK Studios where a cartoon hero battles robots and smashes sparkling crystals across a 5x6 grid. With cascading reels, special symbols, and multipliers, players can win up to 10,000x their stake.
Each winning cluster explodes and triggers cascades until no new wins appear. Robots may then descend from above, attacking the hero if they reach the bottom. To survive, you’ll need Life symbols and bonus features like bombs, airstrikes, and multipliers. Destroy enough robots and you’ll face the Final Boss, with the biggest prizes on offer. A Mass Attack bonus increases the chances of building multipliers and unlocking the Final Boss round.
Mine Defender is a high volatility slot with a 94.00% RTP, playable on both desktop and mobile. Fans of arcade-style games like Space Invaders will enjoy its fast-paced action and explosive gameplay.
The slot is set inside a crystal mine, with a 5x6 grid above the cartoon hero and his spaceship. Symbols include brightly coloured crystals, hearts, robots of various sizes, and bonus icons. The vibrant visuals are complemented by animated effects as cascades, attacks, and power-ups play out.
You can stake from 0.20 to 100.00 per spin using 100 coins. There are 12 preset bet levels, and non-UK players can also buy into bonus features. Symbols pay when at least seven matching icons land anywhere on the grid. Low-value crystal wins start at 0.2x, while giant white crystals can pay up to 100x your stake. The paytable, accessible via the menu, lists symbol payouts and explains all modifiers.
Mine Defender is fully optimised for mobile play on iOS, Android, and Windows devices, with intuitive touch controls and identical features across platforms.
The slot comes packed with unique features and modifiers that trigger during cascades and special rounds:

Despite its relatively low RTP, Mine Defender is an exciting slot filled with modifiers, cascading wins, and battles against robotic enemies. The gameplay is fast and packed with variety, making each spin unpredictable and rewarding.
With the chance to win up to 10,000x your stake and take on the Final Boss, Mine Defender is a must-try for fans of arcade-style slots and high volatility gameplay.
Mine Defender features colourful crystals, along with robots of various sizes, and a wide range of feature symbols on a 5x6 grid. An outer space setting makes it look like a classic game such as Space Invaders.
