About Chain Reactors Slot

Let the symbols drop and connect to make a cash-paying chain reaction in this unusual online slot that plays like a game app! The Chain Reactors slot has Tetris-like gameplay in which the winnings come as a result of connecting blocks of symbols in multiple directions. Then, they explode and leave room for new symbols to land, resulting in new opportunities for big wins.

Developed by OpenBet, the Chain Reactors slot plays on 5 reels and 5 rows. There are no paylines, as the game utilises the Cluster Pays system. As explained above, winning combinations are formed by creating clusters of 5 to 16+ symbols, horizontally or vertically.

You can start playing the Chain Reactors slot as soon as you set your bet per spin. The betting options in this game start as low as £0.20 and go up to £400 per spin, so you have the freedom to choose the bet according to your preferences.

The Chain Reactors slot has several bonus features and a Jackpot. Scoring the jackpot is a matter of making more and bigger chain reactions, which as a result scratch a new notch up on the Jackpot meter to the left of the reel-set. The game has ten symbols, all of which are round emoticon-like creatures that wink, peep their eyes and make funny sounds. 

Design, Symbols and Graphics

Chain Reactors is made of a 5x5 reel set and a style of play that is very common in mobile and tablet game apps. While usually, slots machines have symbols that spin on the reel-set, this game has emoticons. Anyone familiar with the word "chat" in the sense of "online chat" will know that these smileys are emoticons, and they come in various characters. At first look, the game reminds of the Monster Meltdown slot by Endemol Games.

There is the ubiquitous yellow smiley, an orange shades-wearing guy, one that is shaped like a bomb, one with spikes sticking out, there is a purple girl emoticon, and several others that have been given names like Horny, Zoid, Minty, Flame, Brainy and so on. Some of the emoticons appear during the regular game, while some interject on the reel-set during the free spins, and bring with them multipliers on your total winnings. 

The overall design features are not very exciting, so you wouldn't encounter any 3D animations and impressive sequences. The game is rather simple and that is good because it can work on pretty much any smartphone or computer.

RTP, Variance and Payouts of Chain Reactors Slot

The Chain Reactors' theoretical Return to Player outcome surprises with being on the verge of medium to high variance. Considering the style of the game and the added extra features, the Chain Reactors RTP of 94.63% looks like a bargain to us. Plus, the maximum payout can reach 250x the stake on a single spin.

To better understand what these terms mean, you can read our Variance, Volatility and RTP Guide.

Gameplay and Features on Chain Reactors Slot

This game has far more entertaining gameplay than most online slots. That owes to the two gauges that appear on the flanks of the reel set, and in some versions of the game, on the side and on the bottom. 

One of the gauges is the 30+ Pays Jackpot, which has the Flame and the Bomb symbols sitting on top of a bunch of notches, which light up as you score a big chain reaction on the Chain Reactors slot. Each consecutive chain reaction adds a notch to the meter. Now, the reactions that contain the flame symbol fill-up the Flame meter and those with the Bomb fill up the corresponding meter. 

Who knows what happens when either one reaches the top. Will it be a Jackpot meltdown or an avalanche of coins? One sure way of finding out is by playing the game for some time in anticipation of this event.

Meanwhile, on the right side of the reel-set is a field that says Free Fallson top of it. The Free Falls are basically Free Spins in standard online slots. This feature is brought on when the random number (pay) generator triggers seven chain reactions without intermission.

Then the game takes on a new mode in which the reel-set starts to explode in chain reactions that involve the mode-specific symbols Brainy and Cyclo, which bring multipliers of up to 500x and 250x respectively when 15 connect in a reaction. The 15 free rounds can be re-triggered when another seven consecutive chain reactions occur. 

Chain Reactors Slot on Mobile

Even if this is an older game, it has been updated with HTML5 so it’s mobile-friendly. This means that you can enjoy the Chain Reactors slot across mobile devices on any operating system. You can play the game directly in the browser, without the need for any additional downloads.

Chain Reactors Slot Demo

SlotsWise Verdict

We have here a game that you will either love or hate. The unusual reel set and the overall idea and design will throw some people off. Conversely, some people will be into it and go on to play and discover that there is more to it than meets the eye. 

What is more, the Chain Reactors bonus features are tied to cash prizes that many online slots would envy for their amount. Another argument is the Jackpot which is metered, and that means that the player can observe the progression that will trigger the top prize. 

If these arguments are enough, then head on to claim any of the welcome packages that seem fit to you and play the Chain Reactors slot at our recommended online casinos!
