This is Dodgeball meets Frogger, and if you do not know what Frogger is, I am sorry for you. 

Cars

Start off this game you are going to need to divide your space, and create two lines opposite one another, either with pylons or with the side lines on the gym floor. 

Next place your group into two teams. 

Team 1 lineup on the pylon lines you marked with equal numbers of players on each side across the space from each other, creating what looks to be a gauntlet of players. 

Each player on the sidelines gets armed with a dodgeball. 

The other team, Team 2 lines up between the two lines of Team 1.  

Team 2 has to run in down the gym between the armed Team 1 with the goal to get to the other end of the gym without being hit. 

If a player on the Running team is hit, they need to sit down where they were hit and not move, they have become the “Roadkill”. 

This repeats with players from Team 2 running back and forth between Team 1 till there are no players left standing on Team 2. 

Then the teams switch places, Team 1 has to run the gauntlet of players from Team 2

How to Win

Each time players from running Team gets to the other end of the gym without being hit they get a 1 point. 

Team with the most points by the end of 30 mins (or whatever time limit you give) wins the game.
