Slot Overview
Mine Defender breaks away from the usual pickaxe-and-cart mining tropes with a futuristic twist. Developed by ELK Studios, this 5x6 slot runs on a scatter pays mechanic and adds an arcade-style element where a pixelated Hero battles invading robots.
The goal? Collect symbols, defeat enemies, and survive long enough to face a giant Final Boss. With a max win of 10,000x your bet, it's a creative, chaotic alternative to the usual mining fare.
Graphics and Theme
Visually, Mine Defender leans into a retro-futuristic vibe, fusing elements of 1980s arcade gaming with dystopian sci-fi. The grid is set deep underground, but instead of dark tunnels and wooden beams, you get synthy lighting and mechanical invaders. A pixel-style miner stands armed at the bottom of the screen, blasting robots as they descend.
Sound-wise, the synthwave soundtrack plays a key role, reinforcing the nostalgic arcade tone with steady, atmospheric beats. It's like playing Space Invaders... if the invaders were mining robots.
RTP & Volatility
Mine Defender is a medium volatility game with a 94% RTP. The Mine Defender top win is x10,000 your bet.
How to Play
- Select a bet sizefrom 20p.
- Press the spin button to initiate a round.
- Wins form when 7 or more matching symbols appear anywhere on the grid.
- The Hero starts each spin with one life and one shot.
- Cascading wins, Hero attacks, and symbol removals continue until no wins or lives remain.
How to Win
Mine Defender uses a scatter pays system—wins form when 7 or more matching symbols land anywhere on the 5x6 grid. All symbols are gemstone-themed, with larger gems offering higher payouts. Symbols drop down with each cascade, and winning ones are removed, triggering potential chain reactions. Wilds can substitute for any paying symbol to help form winning clusters.
Hero Drops
Enemies can randomly land on the reels, triggering Hero Drops. The Hero fires at these enemies, reducing their hit points. If defeated, they’re replaced with pay or feature symbols. Enemies on the bottom row will retaliate, damaging the Hero unless blocked. If the Hero loses all lives, the round ends. Enemies may also self-destruct via malfunctions, clearing the row.
Feature Symbols
- Life: Adds +1 Hero life (up to 3).
- Shot: Increases shots per round (up to 3).
- Spread: Allows Hero to fire 3 projectiles at once.
- Coin: Awards instant win values, boosted by the global multiplier.
- Multiplier: Increases the global win multiplier.
- Mystery: Transforms into an enemy, wild, or feature symbol.
- Airstrike: Damages 1–6 enemies (3 HP each).
- Laser: Clears a vertical column (3 HP damage).
- Bomb: Deals 3 HP damage to all enemies.
- Pushback: Moves enemies back by one row.
Mini Bosses
Mini Bosses appear in the base game as 2x2 enemies with 10 lives. When defeated, they pay a trophy coin multiplied by the current win multiplier. These don’t disappear after damaging the Hero, so they can attack multiple times if not cleared.
Mass Attack Bonus
Triggered by landing 3 Bonus Scatter symbols, this round shifts the action to a circular grid with the Hero at the center. All multipliers, shots, and spread modifiers collected in the base game carry over. The round ends when the Hero is defeated or you progress to the Final Boss battle.
Other Scatter Pay Slots
View allFinal Boss Battle
