Can someone help me with tip level 19 luxor quest samsung?

I find Level 19 in Luxor Quest / Pharaoh's Pyramid on the Samsung GT-E1230 mobile phone disproportionately difficult too.

It seems just to be a matter of speed and accuracy.

A strategy that seems to work is first set up pairs of matching colored balls when they first progress across the top. (The first two balls in the gun are always the same colour, so you can also always remove the first ball in the chain of that same colour.)

Also, because of the large number of balls that need to be fired in order to win, don't waste too much time moving the gun long distances from side to side. Just start a new colour in the chain / "snake" and hope you can remove it later. 

Also of course, targeting the head of the chain / snake – if the opportunity arises – always buys you a little more time.

There is an "appendix" / "dead end" near the end of the path which may or may not have a purpose? Very occasionally, sometimes a few balls wiggle off track and stop. This may be a software / hardware glitch, or possibly a half implemented feature which may include temporarily "parking" balls, but if this is the case, I have not worked out how to use this.

Level 20 is much easier.
