Main Theme and Storyline

Mine Defender combines an old-school arcade style with slick modern animations for a fresh visual design. The game takes place in a gritty, futuristic mine, with various monsters seeping onto the reels in perilous moments. Its videogame-inspired soundtrack pumps up the action and keeps the energy high.

Mine Defender Slots features & Bonus games

Apart from the Scatters, the slot features an exciting Bonus game with enemies and bosses that can increase multipliers and bring additional prizes. Below, we have studied all the bonus features available in the game.

  1. Scatter Pays

    The slot doesn't have a standard layout: instead, once you have formed a winning combination, all the symbols that are part of it disappear from the grid, making room for new potential wins.

    Mine Defender slot Scatter Pays Seven or more identical symbols pay out anywhere on the reels

  2. Hero

    The Hero has three lives. The hero must shoot as many enemies as possible and protect himself. He shoots the enemies on the row closest to him. Defeated enemies turn into payout or feature symbols. The game ends once the Hero loses all lives.

    Mine Defender slot Hero The Hero Mode continues until you either defeat the Final Boss or lose

  3. Enemies

    Different enemies have different numbers of lives, which makes them easier or harder to destroy. There is also a Mini Boss, a 2x2 enemy with 10 lives, and a Final Boss, a 3x3 enemy with 50 lives. Both of them carry a Trophy coin with multipliers.

    Mine Defender slot Enemies To get Trophy coins with multipliers, defeat the Mini and Final bosses

  4. Mass Attack Bonus Game

    Collect at least three bonus symbols to trigger the Mass Attack bonus game. The grid will become circular, and your Hero will be placed at the centre. Enemies and symbols will keep moving at the Hero from all directions: shoot them to save your life and get extra rewards.

  5. Final Boss Battle

    Once you defeat 50 enemies, the Final Boss mode is activated. You have to collect coins and multipliers to become stronger against the Boss. Once the Boss is defeated, you get the Trophy coin it was carrying.

Our Final Thoughts on the Game

The slot is a refreshing addition to the mining genre thanks to its videogame-like style, which brings the gameplay of a simple online slot to an entirely new level. Even without using the X-iter feature, the bonus game is triggered often, giving the player a taste of fun battle mechanics. Despite the slightly disappointing RTP, we were captured by the slot’s innovative gameplay and colourful graphics.
