Chain Reactors

Chain Reactors is a manic symbol matching game where lining up consecutive reactors sets off HUGE reactions. The more reactions you cause, the more space you have to fill with even MORE reactors which causes even MORE reactions, meaning more CASH PRIZES! It's mental reaction action!

Information & Game Rules

Place your bet, wait for the symbols to drop and watch out for that winning combination! Match five or more consecutive symbols connected either horizontally and/or vertically to win a cash payout. Payout values increase depending upon the payout value of the symbol and the number of matching symbols. But wait a minute, it doesn't end there. Symbols keep dropping until you stop winning.


And don't forget that jackpot prizes could be coming your way too!



Your winnings will be credited to your account immediately.

You will lose your stake amount if you have insufficient winning symbols.

Starting the game

Tap the STAKE button. Tap the arrow buttons, or drag the slider, to increases or decreases your stake amount. Tap OK. The stake value is clearly displayed on the STAKE button.


When you have selected a stake it is time to play. To start Chain Reactors tap the BET button. Symbols will then start dropping.


Auto Play

The Operator may have enabled Auto Play functionality


Auto play is a convenient way to play without having to tap the BET button to start each game. Each play starts automatically until the number of spins set expires or you decide to stop auto play.


To activate auto play, tap the AUTO PLAY button and select the number of plays. Auto plays will commence and the number of auto plays counts down and plays out. Tap the same AUTO PLAY (now STOP) button to stop auto play. Auto play is not available in jurisdictions where it is not permitted.


How do you win?

When the symbol drop is complete, several things may happen.


To win you must match five, or more, consecutive symbols connected either horizontally or vertically. Five, or more, consecutive symbols connected either horizontally or vertically is known as a cluster. It is possible to get more than one cluster in a single game and payouts increase depending on the number of matching symbols you have. Also, the symbols have different payout values.


When the symbol drop stops, any wins will react (that is, disappear). After a short period all symbols associated with a win will disappear, allowing symbols above to fall into the vacant spaces, potentially creating more wins from a single play.


If more wins occur as a result of newly descended symbols, the above sequence is repeated. This process continues until your winning streak ends.


Any winnings are displayed and added automatically to your balance.

Payouts and paytable

A minimum of five consecutive symbols (either vertically or horizontally) is required to win a cash prize.


Tap the PAYTABLE button to see the pay out multiplier values for each symbol.


A Jackpot consists of a fixed minimum amount of money (the seed) that increases by a percentage of incoming stake amounts. When the Jackpot is won the prize fund is reset to its seed amount and the process starts again.



This symbol appearing in a cluster signifies a Jackpot win may be possible, if enough such symbols are present together (see above for rules on clusters). The Jackpot symbol is linked to three Jackpots:


Maxi: Clusters of 7 (or more) wins the top paying progressive seed 100 000 x stake

Midi: Clusters of 6 wins the middle paying progressive seed 10 000 x stake

Mini: Clusters of 5 wins the lowest paying progressive seed 1 000 x stake


The prize amount for each Jackpot (Maxi, Midi and Mini) is displayed clearly. Which Jackpot is won depends upon the number of Jackpot symbols appearing in the win line within a cluster. The chance of winning the jackpot is the same for all qualifying bet amounts.


Important points to note about Jackpots:


–      Jackpots are available for the Real play version of Chain Reactors only.

–      The minimum seed amount for the Jackpot depends upon the minimum stake amount that is set by the site operator.

–      The seeds (or starting values for the respective Jackpots) are: Mini= 1000, Midi= 10,000, Max= 100,000.

–      Winning a Jackpot neither contributes to, or is affected by the daily cumulative winnings limit.

–      If the players stake is greater or equal to the minimum qualifying stake then the amount contributed to the Jackpot by the operator will be a percentage of the total stake amount, as follows: Mini=3.0%, Midi=3.0%, Maxi=1.0%.

–      Contributions to the Jackpot come solely from the operator and are not taken from any bets placed by the player.

–      It is not possible for two players to simultaneously win the Jackpot. The Jackpot is locked when it is being won. This means that no other bets will be accepted for it and only one player at a time is able to win it.

–      When two or more players appear to simultaneously trigger the jackpot, the first player will be awarded the jackpot and the others will receive a message warning them that the jackpot was won by other player. The current play is cancelled and the player will have the opportunity to play again after being informed of the new jackpot values.

–      Each Jackpot prize (Mini, Midi and Maxi) pays out once only per play. Any further 'wins' of that Jackpot will generate a reaction but not a prize.

–      This game has a maximum consecutive drop limit of 100 drops, after reaching 100 drops the current game in progress will end.
