Burst Balls

Inspired by mobile app game 'Jump Ball Blast' with a TWIST!

How to play:

1. Click on GREEN/BLUE balls to earn points
2. Avoid pressing RED Bombs
3. All balls/bombs has a counter which reduces everytime it collides with a wall.
4. Bomb simply dissapear when counter goes to zero.
5. You lose a live if Ball counter goes to zero or if you pressed on a RED Bomb
6. Challenge your friends and earn the highest score!
