This is the trick to overcome a captch with a puzzle piece.
First investigate:
there are only 4 puzzle pieces
there is a hight difference but the slider will drop the piece on the right place.
So 'Append record' the missing piece and find the mouse location.
Let the bot 'detect' the new missing piece location and get the mouse coordinates
then let the slider with "drag and drop"slide it to those mouse coordinates.
In Max 4x the bot wil overcome the Capcha. Check the movie I've added.
But again there is always a "cure"; it has always 4 symbols above and three under: so the positions are almost the same. so max 21 different clicks different combinations and using loop to try every combination. I'll keep you posted if this succeeds
