Besides stunning visuals from Red Tiger Gaming, Monsters Unchained also features unique gameplay mechanics. But before we get to those we have to cover the base game. The game is played on a 5×3 grid with 15,625 possible winning ways instead of paylines.

You score wins by arranging at least 3 identical symbols on consecutive reels starting from the leftmost one. As long as the reels are adjacent and they start from the left, vertical position of the symbols does not matter. Multiple unique winning ways are combined.

The game is played in 10-spin increments and the 10th spin is when the extra features activate if you have landed any. More on this later.

Furthermore, there are 9 regular symbols where the 5 low-wins appear as card symbols A, K, Q, J and 10. The 4 high-wins appear as chains, an axe, a lantern and a treasure chest. These are the basics so let us more to the extra features.

Casino Bloke Best tips for Monsters Unchained

  • 1All the monster abilities always trigger on the 10th spin if you have landed at least one Chain Breaker scatter during the current sequence
  • 2You cannot change your bet amount before the 10th spin for bonuses as this resets the sequence for the new amount


Monsters Unchained by Red Tiger Gaming has some of the most exciting base game features we have seen in a while. They are all about unleashing the power of the Minotaur, Medusa and Cerberus with their respective scatters for bonus mechanics.

There is a unique system where you are going through 10-spin sequences for each bet amount that repeat once they reach 10. You can keep track with the counter in the top-left and on the 10th spin the extra features trigger if you have landed any. Let us cover how they work:

  1. Chain Breaker Scatters – The Minotaur (Red), Medusa (Green) and Cerberus (Blue) each have their own uniquely-colored chain break scatter. Each scatter breaks one of three chains for the corresponding monster during the 10-spin sequence. If at least one chain for any monster was broken during the current sequence, that monster’s special feature activates on the 10th
  2. Minotaur – The Minotaur expands the playing grid for each of his chains that were broken.
  3. Medusa – The more of her chains are broken the more wilds Medusa spawns on the board.
  4. Cerberus – Cerberus grants a winning multiplier on the 10th spin that increases based on his broken chains.
  5. Monster Spins – Landing at least 3 monster spin scatters triggers free spins with monster features active throughout the feature. Each fully unchained monster also awards 3 extra free spins.

As you can see, this title has a strong base game with an even more exciting free spins mode.


This slot game has the standard Red Tiger Gaming betting and payout options. You can wager anywhere from $0.20 to $20 for a chance to win the maximum payout which is 10,500x the bet. The return-to-player value of Monsters Unchained is 96.00% which is the average for modern slots. Gameplay is highly volatile due to the random nature of chain breaker scatters.

That said, there is one constant for each bet amount, the 10th spin will always trigger extra features if any were landed. This does not reduce volatility by that much but it is still a reliable element to keep track of.

As for regular symbol payouts, the most you can get is for 6 symbols in a winning way with expanded reels from the Minotaur. In this case, the low-win symbols will get you a maximum of 0.8x the bet. The high-wins are not that far ahead with 3x the bet for six highest-paying symbols in a line. These values are not the best and could use a little improvement.

what we like

  • Three exciting monster features that trigger on the 10th spin
  • Expanding reels, extra wilds and multipliers
  • Win up to 10,500x your bet

what we don’t like

  • Low regular symbol payouts


The Monsters Unchained slot by Red Tiger is one of the most exciting slot projects of latter Summer 2023. Visually the game is gorgeous and quite immersive into Greek mythology with excellent creature designs and backgrounds. The gameplay loop is unique in that it relies on the 10 spins cycle where extra features trigger on the final spin.

That said, the regular symbol payouts are a little bit low reaching a maximum of 3x the bet. These lower values can be compensated for if you land monster features like multipliers of wilds but they could still use a little work. Still, this is an excellent Red Tiger Gaming title that we recommend everyone try at least once.
