can anyone explain how to fish and cook?

Take a look at these two links:

Remember that it is more about timing than speed clicking, don't injure your index finger.

You want to keep hitting 'reel' and when you see 'snag' you hit the 'snag counter'.

It's important to get the timing right however so that you can be prepared for that snag counter. I usually wait about half a tick on the top bar before I click 'reel'. YOu can always release the line too if your top bar (rod health) gets too low compared to the bottom bar (how close you are to reelin a fish in).

PM me if you need any additional help
