Fail Alien comes to us from Merkur. Presentation-wise it's themed around space and fantasy, and it leans toward a high-variance maths model at 94.64% RTP. Under the hood you'll find 5 reels and 10 paylines.
Dig into the bonuses and Fail Alien starts to stand out. Look out for scatter symbols that unlock free spins and extra bonus rounds. The high volatility means patience is rewarded — expect quiet spells broken by bigger hits. On balance, Fail Alien is a no-frills option worth a few spins in the demo first.
The RTP of 94.64% is below the industry average of ~96%. This is common for older slots or those with special features. The lower RTP may be offset by unique mechanics or higher maximum win potential.
High volatility means longer gaps between wins, but when wins do land, they can be significantly larger. A bigger bankroll and patience are recommended for this type of slot.
About 1 in 3 spins results in a win. This is a moderate hit frequency that balances win frequency with payout size.
Fail Alien features scatter symbols that can trigger free spins rounds. Landing the required number of scatter symbols anywhere on the reels activates the free spins feature, giving you extra chances to win without additional bets. During free spins, special modifiers may apply to boost your winning potential.
