When a screw is stripped, there are several methods to remove it. Here are some tips and tricks from the search results:

1. Use a different style of screwdriver or bit.
2. Use pliers to get a firm grip on the screw and turn it out.
3. Use a rubber band or steel wool to add traction to the screw head.
4. Use a hot glue gun to add material to the screw head and let it cool before turning it out.
5. Apply a liquid abrasive to the screw head to give the screwdriver or drill bit something to grip.
6. Drill a hole into the head of the screw and use a screw extractor bit to remove it.
7. Try a different screwdriver or size of screwdriver.
8. Cut a new slot into the screw head using a rotary saw or oscillating tool.
9. Use a drill bit slightly smaller than the screw head to loosen it and remove it with pliers.
10. Use a screw extractor tool.

Its important to be patient and not force the screw, as this can cause it to strip further. If one method doesnt work, try another.
