League uses additional rules and game variants for each game to make them interesting. Here is a complete list of all the tweaks and changes the League has come up with over the years.

Friendly Fire
In a game where Friendly Fire is used it is possible to tag your own team-mates. It is not a good thing however. Everytime you tag a team-mate you lose 45 points, 1 energy, and 1 credit.

Gimp Rules
The Blazer Tag arena is three stories tall. It is the largest arena in Texas. Gimp Rules means that all players must remain on the first floor the entire game. Any player that goes upstairs will be removed from the game. This creates a more of enclosed battle on the floor and when used on certain games it makes it an intense experience.
---Note: This variation was created in honor of a league member in a wheelchair (codename "Gimp").---

Sniper
Basically Gimp Rules, except each team gets one "sniper" that stays upstairs the entire game and wreaks havoc on the players on the floor.

Invisible Sniper
Just like Sniper except the snipers are invisible.

Captain Sniper
Just like Sniper except each teams Captain is the sniper.

Equalizer Rules
Just like Gimp Rules, except the team with the worst record gets a sniper and the team with the better record doesn't.
