Reactoonz is a popular Cascading Slots game developed by Play’n GO. Players are invited to trigger reels containing colourful symbols in the form of aliens. When combinations of three or more of the same symbols appear on the screen, they disappear, making way for new symbols that can lead to even bigger wins.

Reactoonz has several features that make the game unique and exciting. For example, the game has a multiplier system that increases the payouts many times over. Reactoonz also has special features such as “Gargantoon”, a huge symbol that can bring big wins, and “Quantum Leap”, which activates various bonus features.

Reactoonz has become very popular among casino and cash game enthusiasts, as with patience you can win big. But it is also available in free mode for those who just want to play a fun casual game.


The essence of the game Reactoonz

The main point of the game is, of course, to call Gargantoon by filling in the scale in the top right corner of the screen. But even if you don’t, you’ll get plenty of bonuses along the way. If your combination fails at any level. It will start to fill up from scratch.

Here are some important things to know to get you started playing Reactoonz:

In Reactoonz, winnings are paid out according to a cascade system. This means that when you win, symbols disappear and new ones appear in their place. If you win again, the process repeats. This can lead to multiple wins in a row.

Game algorithm

The main objective of Reactoonz is to match clusters of symbols on a 7×7 grid. Winning clusters are removed from the grid, and new symbols fall into the empty spaces, potentially creating more winning clusters. The game also includes special features such as Wild symbols, Gargantoon symbols, and Quantum Leap charges that can trigger various bonuses.

The game’s algorithm determines the probability of each symbol appearing on the grid and the likelihood of winning clusters based on the symbol’s position and adjacent symbols. The algorithm also determines the frequency and value of the different bonuses and the chances of triggering them.

Like all casino games, Reactoonz uses a random number generator (RNG) to ensure that each spin’s outcome is entirely random and unbiased. The RNG is a complex computer program that generates random numbers and uses them to determine the game’s results. The RNG is independently audited and tested to ensure that it meets industry standards for fairness and randomness.

In summary, while the specific details of Reactoonz’s algorithm are not publicly disclosed, we can infer that it uses a combination of random number generation and symbol clustering probabilities to determine the game’s outcomes.

How to play:

  1. Choose your bet size: Before you start playing, you need to choose your bet size by adjusting the coin value and the number of coins you want to bet per spin.
  2. Spin the reels: Once you’ve chosen your bet size, click on the “spin” button to start the game. The symbols on the grid will start falling and forming clusters.
  3. Form clusters of matching symbols: Your goal is to form clusters of matching symbols on the grid. Clusters are formed when symbols are adjacent to each other, either horizontally or vertically. The more symbols in a cluster, the higher the payout.
  4. Trigger bonuses: Reactoonz has several bonuses that can be triggered by forming clusters or by using Quantum Leap charges. These bonuses can increase your chances of winning and boost your payouts.
  5. Keep playing: The game continues until there are no more winning clusters on the grid. If you have any winnings, they will be automatically added to your balance.

Reactoonz is a high-energy and fast-paced game that offers the chance to win big prizes. However, it’s important to gamble responsibly and within your means. Make sure to set a budget for your play and never bet more than you can afford to lose.

There may not be any free spins in this Reactoonz game, but you won’t notice, as the cascading reels make one spin feel like it could last forever. This slots game on mobile keeps the action going, but beware of false certainty.

Like Royal Masquerade, this is a high variance slot, so you’ll need to be patient to get some truly heartbreaking wins. But those wins are there; you can get 4,570 times your stake on a single spin, and with the full chain reaction of spin wins, the total can be much more.

A dangerous game that can lure you in with great graphics and big wins, but it should be reserved for those who have been playing slots for a while.
