After the 50 score stage, you will usually have to navigate around 3 worms. When you have the first two worms correctly guided by the first section, guide the 3rd ghost's intersection first before you solve the second layer intersections of the other 2.<br>

If you have more than 3-5 in a row of the same colour (or the same first intersection split), it is easiest to lose concentration then. Be alert!<br>

The game is somewhat slow, so scoring anything into the 100s and even up to 1000 perhaps will take a very long time. You cannot hold concentration for that long, so make good judgements of when to take a mental break.
