Get two teams of friends together with either a football or a real rugby ball. The rules are you can’t run if you have your hands on the ball, all passes have to be underhand, defense must count to ten (normal counting, no counting to ten in two seconds) before rushing the Quarterback, if the ball hits the ground its a turnover to the other team. The Quarterback can run to evade the people rushing in, but can not go past the line where the ball was snapped. Also to make a try (one point) you must go to the end zone and touch the ball to the floor. http://www.worldrugbyshop.com/departments-balls.html
This is a mix of football and straight mayhem. This game can be very fun if you have a bunch of friends and a big field. The main rule is that if you have the ball run from one side of the field to the other as many times as you can without getting wrecked. For every time you make it across you gain one point. When the carrier gets tackled he must stop were he is, throw the ball straight up into the air to give every player a fair chance to run the ball and get points. If that’s you catching the ball….RUN!!!!!! Its every person on the field against the the one who is running with the ball, no teams. You can tweak the rules so you can play teams, have the teams block for their teammate who is carrying the ball. http://www.wilson.com/en-us/football/footballs/
A really good way to have some good times with all your friends is to go to the closest bowling lanes. Having fun bowling makes a lot of good memories. I suggest putting up the bumpers so you don’t get gutter balls. Also the bumpers come in handy so you and your friends can act dumb and do some crazy throws, to make a laugh. Hopefully your local bowling place has neon lights that light up the lanes after dark. I don’t know why, but going when they have the lights on always makes the night better. Some places have fluorescent bowling balls that will light up when the neon lights shine onto the ball.
Usually when people go to the beach they get a bunch of friends together and start a pick up game at the closest beach. For those people with a small amount of friends a good way to play football at the beach is to play catch in the water, when you catch the ball find the largest wave and plow into it. Test yourself by hitting the biggest wave you can find, and see if you can stay standing after contact. Try throwing a couple diving catches to your friends. http://www.wilson.com/en-us/football/footballs/
Some people like to make little balloons that can be thrown really far but its better to sneak up behind someone and lay the nuke of water balloons on people. These balloons can get really big, like really big. If you do it right it will be very beautiful. The best way to make these is to buy the biggest ones you can find, but to make them go above and beyond their limit you must stretch the balloon before you put water into it, and when you fill them up u must do it in a giant bucket of water. Gravity is usually what causes the balloons to pop while being filled, so the water lessens the effect of the water being pulled by gravity. Check this out, give it a try and give me some feedback http://www.youtube.com/watch?v=Lom70GtwtEU.
Handball using a racquetball is much better than using a traditional playground ball. I used to play this during recess when I went to elementary school. All you need is a racquetball, a big wall, and a bunch of friends. Here is where you can get the balls for the game http://www.holabirdsports.com/racquetball/balls.html.
Paintball is one of the best sports to play. It may hurt, but the adrenaline pumping through your body dulls the sharp pains. The best way to do this and cheapest is to gather as many friends and equipment as you can, find an open area in a forest or an enclosed area, set up a course giving enough cover for each team. These are my favorite markers out there (paintball guns) http://www.paintballguns.net/Kingman/Paintball_Guns/. There are a lot of places that have courses already set up, but they are usually expensive http://www.skirmish.com/.
