How to Play School Wars Unblocked Game
School Wars Unblocked game is a group fight among students at the school. There are four groups that are identified by Black, Yellow, Green, and Purple Colors. You need to choose a color of the group when you start. Click on the tile of your group, and then click on any other tile on the group to bring one group member there. This way you can call all your group members. Move slowly in the group, else the other group members will kill you.
If you want to explore the entire area or just want to see the other group members, click on the shadow kind thing on the small image (located on the bottom right corner) and then move it anywhere you want.
