When it comes to betting options and payouts, the game is rather low-stakes as is usual for Red Tiger slots. The most you can bet in the game is $20. This prevents over-investing into a single spin which is healthy. The maximum win for the game is 10,500x the bet with a 96.00% RTP value which is dead centre average.

Regular symbol payouts are quite low which is definitely a flaw of the game. The most you can win for low-win symbols is 0.8x the bet for 6 of them in a winning way when the grid is expanded. The high-wins are not much better at 3x the bet win for the highest-paying symbol. These low payout values can be compensated by extra features but you definitely feel the low stakes low win nature of the game.


Now for the most fun part of the Monsters Unchained slot. The game has a unique system where you collect extra features in a 10-spin cycle. Then, if you managed to collect any during those 9 spins, the 10th spin of the cycle always triggers those extra features. This is how it works:

  • Chain Breaker Scatters – The Minotaur, Medusa and Cerberus have their unique red, green, and blue scatters respectively. In the 10-spin cycle sequence of the game, landing any scatter during the 9 spins breaks one of three chains for each monster. Reds break chains for the Minotaur, greens break chains for the Medusa and so on. If any chains were broken for any monster, that monster’s special feature is activated on the 10th spin of the cycle.
  • Minotaur – Expands the playing grid for each of his chains that were broken.
  • Medusa – Spawns random wilds on the board for each of her broken chains.
  • Cerberus – Grants winning multipliers that increased based on how many of his chains you broke.
  • Monster Spins – Landing 3 monster spin scatters triggers free spins with monster features. If you break all three chains for any monster during free spins you get 3 extra free spins.

The 10-spin cycle is an interesting mechanic that lets you know when you will be getting extra features if any. Cycles are saved for each bet amount so you cannot change your bet to a higher one before the 10th spin.


The Monsters Unchained slot by Red Tiger Gaming brings both a great theme and a neat idea to the modern slot world. The exciting extra features of each monster combined with the 10-spin cycle is a fun gameplay loop. Between expanding reels, extra wilds and win multipliers, there is a lot of replayability in this game which we like. Furthermore, the base game has all the extra features implemented so you do not have to wait for free spins.

That said, the game does suffer slightly from low regular symbol payouts. The RTP value is average and nothing special. If you do not mind the lower payouts then you will enjoy this game. Red Tiger Gaming has done an excellent job with the art style and extra features.
