I have two self-made games, but they're embarassing.
1.) I have one game that's a solitare card game, and you have eight teams that all play one another once (discluding four-team playoff) and it's a hockey game. Each team gets one card per period, and if the card is between 2-7, then they did not score that period, if it is between 8-J, then they scored one goal that period, Q-K is two goals and an ace is three goals. The highest card value wins in overtime, if necessary, the same value, pursuant to the above, results in a tie.
Anyway, you can just start with the top team on the list playing each team below it once, so you might end up with something like:
Philadelphia Flyers: 1-0, 1-1, 2-1, 3-1, 3-2, 4-2, 5-2
Toronto Maple Leafs: 0-1
Boston Bruins: 1-0
Pittsburgh Penguins: 0-1
Montreal Canadiens: 0-1
Columbus Blue Jackets: 1-0
Detroit Red Wings: 0-1
New Jersey Devils: 0-1
Then, the Toronto Maple Leafs would play every team below them once, and so on.
The Top 4 teams go to the Playoffs, and any ties are decided by head-to-head, if there's a three-way tie and head-to-head doesn't work, then it goes to points scored.
2.) Tennis Ding
-I worked at a tennis court once when I was eighteen and for four months. I was alone up there much of the time, and it could get boring if you were unwilling to be imaginative.
Anyway, there was a picnic table and a gold plaque above this outdoor fireplace. I would set up eight teams which were just entirely comprised of me playing the game with myself. Each team would get ten throws per game, if you threw the ball straight at the plaque and caught it in the air you would get five points, but it was risky, because if you did anything other than catch it in the air, you got nothing, also, if you missed the plaque, you got nothing. If you bounced the ball off of the picnic table, hit the plaque, and caught it in the air that was three points. If you bounced the ball off the table, hit the plaque, and caught it on the first bounce, that was two points. If you bounced the ball off the table, missed the plaque, hit the wall, and caught it in the air, that was one point. Any other result was zero points.
The Top 4 teams went to the Playoffs, same rules.
It was funny because sometimes friends would come to visit me, (it was allowed as long as you didn't ignore customers, and I never played the game when I had customers, I read a book and listened to the radio) and I would continue my game while they were pulling into the lot because I didn't really care what they thought. Anyway, they'd come up looking at me like I was crazy because I'd be bouncing the ball off the picnic table, hitting the plaque, diving on cement to catch the ball before it bounced, and writing stuff in a notebook after every few throws, looking batshit crazy!
They weren't laughing after they inquired about the Rules and got a few throws in, though. It was a highly addictive game! Pretty soon I had 1-3 of my friends at work with me everyday because they wanted to play against me!!!***
***I tried to make the Rules more complicated, one point if it hit the plaque and you caught it after two bounces, double-points for throwing with your opposite hand, half-point bonuses for catching with your opposite hand only...but they never caught on.
