Check Out Whats NEW!!

Introducing our newest addition



DOZER'S Games has worked hard to bring you the ultimate gaming experience right to your front door! Now we are bring you the newest and hottest contact sport in the nation. 


So Just what is a KnockerBall™ ? – A Knockerball™ is a single chamber inflatable sphere with inner handles and adjustable shoulder straps. Knockerballs™ range from 1.2 Meters to 1.5 Meters and the size or fit is predicated on your height. Knockerballs™ can be used singularly to perfect your rolls, flips, and wheels or can be used with two or more to enter a realm of rip roaring, knocking fun times. People who use Knockerball™ are sometimes referred to as “Knocker Ballers” and they describe the sensation as almost defying gravity. This sport is so new and we are proud to be instrumental in introducing one of the coolest products to come along in a long time to the U.S.A. Till now, Knockerball™ or “bubble soccer” has been gaining traction in Europe, Australia, Japan, and elsewhere. Leagues are opening up all over the United States so isn’t it time you “GET IN THE BALL “and see what you’ve been missing?


What is provided with the rental event? – We provide the full setup of the Knockerballs™ (delivery, inflation and breakdown). We will also provide you with some options of “games” to play and soccer balls.


Do we provide permits for use at State or City and County Parks? – No, it is up to the individuals renting to obtain a permit from the Parks Department if they are needed.


What height do I need to be to use Knockerball™? – To really be able to use the Knockerball™ we recommend at least 4′ 0″ for the 1.3 ball because the balls do weigh 14-17 lbs. But to just get inside of a ball and roll around we have had many young children have a blast. Anyone over 5′ 5″ will have more fun with the 1.5 ball.How old do I have to be to use Knockerball™? – There is no age requirement per say… is more of a height and strength limit because it may be difficult to play Knocker Soccer and carry the ball on your shoulders (14- 17 lbs.) but people of all ages can at least get inside the balls and just roll around. Players under 5’6″ should use the small (1.3m) ball, while players over 5’6″ are fine with the regular size (1.5m) ball.


Do we own KnockerBalls™? – No, Dozers Games is an independent, family owned company. Knockerball™ is the Trademark name of the ball we employ in our business.

Types of Games We Play



(Game length determined at game time)


Knocker Soccer IS CO-ED

NO Positions, coaches or goalies needed

You can bump someone at any time, OTHER than when they are already on the ground

NO intentional contact with shoes or feet to the bubbles

NO intentional contact with another player with anything other than your bubble

NO cleats or shoes with sharp points, edges, buckles, or straps

No alcohol is to be consumed while playing bubble soccer

No sharp objects inside of the bubble (all jewelry must be taken off)

No intentional action which may cause damage to the bubbles.



Referee blows the Whistle. Every man for himself! Once a player is taken off their feet they leave the field until next round. Last bubble standing is the winner!



One person stands in the center of the field. Everyone else starts on one side of the court. When whistle is blown, all players on side run to the other side. The player in the middle tries to knock the players down. If someone IS knocked down then that player must join the player in the middle. Continue until only One player is left who is the WINNER!



2 Teams. Each team picks a captain. Every time a team’s captain is knocked to the ground, the other team scores a point. (5 min. Rounds)



Make a circle of cones. Blow whistle. Everyone tries to bump each other outside the circle. Last person in circle WINS!



Two lines, One Runner. Can you make it to the end?
