6 explosions , needs a bit of luck but aim for planes , if lucky you will get multi planes, then you can work out the rest of explosions on ground level.
there are a few issues with the game but it is still a good start. as for those asking for a point to the game , please remember that while at work not everyone has time to play the full length games on kong, so some short time wasters are well worth having. you can challenge your friends to beat your score etc . thats my 2 cents
