This is a fun game my friends and I came up with.

Step 1: Place to Play

Find a park, alley or anywhere you can hide very well.

The best time to play is at night, but you can play it in the day.

Step 2: The Rules

The rules are simple.

You divide into 2 small groups: ninjas and assassins.
The ninjas are "IT" first and they can tag anywhere on the body.
The assasians are the hiders, but the assasians can get the ninja out if they tag them on the back.
The first few people to get tagged, from either ninjas or assassins, are "IT."
