Partygaming has had a busy summer, releasing many classic slot machines with a twist, and even other slot games that are nothing like anything else on the market. One of their newest unique games is Chain Reactors -- a slot machine bereft of ordinary reels and pay lines and other classic slot features but still big on entertainment.

Chain Reactors, in a few words, is just really fun to play. The upbeat arcade music and crazy 3D faces bring plenty of entertainment to this relatively simplistic slot machine game. When you push play and hear all the characters shout "WEE!"; you realize that games, above all else, are supposed to be fun.

There aren't any legitimate "slots," but you will find characters like Spiky, the wide-eyed red ball; Sunny, an orange wearing glasses; Cyclo, a one-eyed green guy; Goldie, the quintessential smiley face; Flirty, a lipstick-wearing pink heart; and Zoid, a blinking, screaming, slinky-like character.

Goldie, the big smile, is the highest-paying symbol, with Zoid and Flirty following. This one-of-a-kind slots game lets you win by creating a "chain reaction" of characters; and the bigger the chain, the bigger your prize.

You won't find any wild slots, scatters symbols or bonus games with Chain Reactors, but with cool graphics and music, 72 winning combos and an auto play feature that lets you sit back and enjoy the action while raking up the coins, it's still a very amusing--and even addicting--slot machine.

Players can bet 1 coin at a time with a range of 10 cents all the way up to $500 dollars, making Chain Reactors a great choice for beginning players or high-rolling slot enthusiasts.
