Welcome to Chain Reactors 100

Chain Reactors 100 is a crazy game where you are paid out for chains of animated matching symbols. The symbols explode and tumble down to make room for more! Payouts vary between symbols and the larger the chain, the bigger the payout.

There are also 3 progressive jackpots to be won!

Setting your stake amount
Click the Up or Down buttons in the STAKE box. Each click either increases or decreases your stake amount.

Starting the game
When you have selected a stake it is time to play. To start Chain Reactors 100 click the BET button. Symbols will then start dropping.

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. 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. 

Payouts and paytable
A minimum of five consecutive symbols (either vertically or horizontally) are required to win a cash prize. Payouts, per symbol, ascend in value depending on how many consecutive symbols there are.

Above the Payouts window is the Jackpots window. It displays the details for the progressive jackpots (in real play only).
