Mine Defender RTP and Wagering

Mine Defender - RTP and Wagering

Mine Defender uses five reels and six rows and is a scatter-pay slot. To land a win, players need to land seven or more matching symbols anywhere across the grid. 

This slot game has a cascading feature, which sees winning symbols removed from the grid and new ones fall into their place. 

Click the stacks of coins in the bottom left to see the options and select your stake. The options start at £0.20 and reach up to £100, which is a solid range that will cover most budgets. 

The game has a medium volatility rating, with players able to land a maximum win of 10,000x their stake. However, like a lot of ELK Studio titles, the game does fall short in the RTP department, offering just 94%.

Mine Defender Symbols and Audio & Video Design

Mine Defender takes place at the bottom of a mine. The titular heroic mine defender sits atop a gun at the bottom of the screen. ELK Studios has opted for a slightly cartoonish take on the genre, with the game looking perfect on mobile screens. 

 The symbols are various colours of precious crystal formations. The most valuable is the pearlescent crystal symbol, which offers 100x your stake if you land 15 or more.

The Wild symbol includes four crystals bound together by the word wild. It can substitute for any paying symbol to complete a win. Bonus symbols are collected before they transform into the maximum value, pearlescent crystal symbols.

Mine Defender - Features

Mass Attack Bonus Game

Collecting three Bonus symbols launches this bonus game, which takes place on a different set of reels. It places the hero on a central platform with 10 paths leading to it. Each path contains five symbols, and the hero receives five lives. Typical gameplay occurs during the bonus round, and it ends when the hero is defeated three times and loses all their lives.

Final Boss Battle

The Final Boss Battle occurs if you defeat 50 enemies during gameplay. The battle involves a three-by-three Final Boss enemy with 50 lives and takes place on a grid containing enemies, coins, and multipliers. The feature ends when the Final Boss or the Hero is defeated, and the trophy coin it carries is awarded.

Mine Defender Final Thoughts

Mine Defender is an engaging scatter-pay slot game with a great design, unique gameplay mechanics, and a solid maximum win. The game has pulled inspiration from video games, and is all the better for it, serving up some really fun gameplay sequences. The biggest drawback here is the low RTP, which does leave a bit of a sour taste. Outside of this, though, the game offers a really fun alternative experience.
