Many games include balls. Football, squareball, softball, tennisball. Here are some of the others. Murderball / Deathball : A pleasing mix of football, it, and violence. A football was kicked, and if it hit you without you controlling it and returning the ball, then you were chased and pulped.

Pissball : A new fluffy tennis ball is taken to the toilets and placed in the long piss filled gutter of the school urinal. Once nicely soaked it was hooked up with a deft foot and dribbled to the centre of the school yard. To commence the game, shout "PISS BALL" and boot the ball at the victim of your choice. This had three resulting outcomes. (1) A direct hit. The victim would smell like a trevor for the rest of the day, and a hundred boys would share the pride of having their piss on him. (2) The more sporty types with the quick reflexes may go for a catch. Pissy hand ensues.. (3) Miss. Needless to say a lot of kids stank of a lot of piss.

Domball : Not to be confused with DoomBall. Similar to Australian rules football, two (sloppily defined) teams of people would attempt to score by carrying, kicking or throwing Dominic to their end of the common room. Additional points were allegedly available for mid-play manoeuvres such as posting (qv). Games were started unpredictably with the rallying cry of "DOMBALL!" whenever Dominic was in the common room, which became decreasingly frequent as the game grew in popularity.

Hennis : a game where one skinny lad is pushed between two bigger lads in a game of mock tennis. the winner is the player who makes the skinny lad fall over/cry/be sick etc etc

Chinese Deathball:
A semi-mythical variant of Deathball that no-one seems to have directly played but rather only heard about.
I don't actually know what makes it so radically different from normal deathball, maybe only Chinese kids were allowed to play it, or communists.

Speed Ball
No ball involved, no real relation with the futuristic sport of the same name. Few rules as i remember. A group forms two teams and then run at each other attempting to rugby tackle someone on the opposing team.
Quickest method to disable your opponent was to allign your knee cap with his balls. However only attempt this if you can realistically claim it was an accident. If not convincing your gasping opponent's team would target only you and then life wasn't really worth living anymore. LEGGIT

Kill The Dill with the Pill.
Two Teams. One Hacky Sack.
Some vague rule about getting it to the other side of the field.
Main rule was to attempt to flatten whoever happened to get thrown the "pill"

don't forget "high contact football" which involves such delights as the purposefully missaimed double footed sliding tackle and the sliding tackle with with head up...oh and not to forget the fists first offensive goal keeping tecniques that usually involved jumping on the ball and punching the striker square in his nuts

I once ended up headbutting the teacher in the balls, i dunno if I should be proud of disturbed.

Not pissy balls par ce but to do with pissing and football. Each lunch time we played football and each lunchtime we lost to the other team. This eventually got to one of my friends so much, that after yet another 34-2 defeat he nonchalantly walked up the opposing teams goal, two school bags, and preceeded to urinate onto and into one of the bags untill he felt justice had been done. Being a rather large child he got away with it too

Wallball: Squash with violence.

you fling a tennis ball at the gym wall, and one of the other players must try to catch it. If somebody fails to catch it they must stand by the wall and everybody has a go at flinging the tennisball at you as hard as they can.

Should you miss the wall altogether, you would be roundly mocked then pummled with tennisballs. Although hitting somebody in the face or groin was officially frowned upon, hilarious 'accidents' happened with worrying frequency.

I know yuo said you didn't want anything more on MurderBall, but, bear with me....
Posh school, all boys class, so 30 BIG 15 year old lads. Teacher is using numbers to define who is on the pitch at any one time. Shouts out "prime numbers". My mate Jamie Phelps runs out - big scuffle at the other end, Jamie on the bottom, ends up with a broken arm. Ask him the next day what his number was ? "Six". "Ah, in that case you deserve a fucking broken arm..."

fouly fouly football. football with no rules. bye bye clean shirts, unbruised shins. only the hard kids would play this. too much of a violent game for mere softies like me.

Waccaball

this game involved a ball made of a piece of paper rolled up. the game started with someone throwing said ball and from then on it could only be touched by a cupped hand. it was then passed on. the most famous incident was Botty, the legend, who caught it with a cupped hand in his armpit thus making him look like a monkey scratching itself. he was a beast was Botty.

Nzekwe Ball - A ball of flaming paper is batted around a table using "home contact books" as makeshift raquettes. If the ball of flaming paper lands in your lap (you're blazer gets burnt and your mother goes nuts, cos they ain't cheap...)or you let it pass you, you lose. The game can also be played in a team variatoin we're tables comete with one another from opposite sides of the room. Great fun, alot of trouble if you get caught.

Space invaders - One or two smaller boys would slowly move sideways across an open doorway in a space invaders style, whilst bigger boys would throw tennis balls at them. Very hard. Very much like a one-way game of dodgeball.

Occasionally, the tennis balls were substituted for rugby balls and waterpolo balls. With predictably painful results.
