Threefold repetition

Why can your opponents play very very quickly and deny you a draw in a threefold repetition?? Or should you claim draw before making move??

Yes, claiming a draw before making the final repeating move will work.

Thank you kindly for responding revoof.

In the settings there's an option to automatically claim a draw on 3-fold, which I recommend.

Thank You for the information OldPalHappy.
