Each jumper has a small trace connecting the middle pad to the default
polarity setting. The small trace is sometimes difficult to see, but it is a thin
stripe of metal that should show up as a lighter color red. Using a hobby
knife (aka x-acto knife), cut the default traces:
Using your soldering iron, close a jumper between the middle pad and the
other outside pad:
The polarity of the traces running to that LED should now be swapped, and
your LED should be lighting up.
Resources and Going Further
If you'd like to further understand how the Binary Blaster design works, a
good place to start is looking at the design files. You can get the complete
hardware and firmware files at the GitHub Repository here:

Your Binary Blaster game is re-programmable with Arduino. This means
that you can change the rules of the game, add more features, or turn it into
a completely different project. For more information about how to re-
program using Arduino, check out this following tutorial:

If it's more soldering that you're after, here are a few suggestions for other
