No Mouse (Option 1)
Sometimes we get a little too comfortable with the mouse, and forget about how much
it slows us down when we have a job to do. Our text editors and IDEs are full of handy
keyboard shortcuts for changing and navigating our code.
Text editor only (Option 2)

Evil Pair
This is very much like Ping Pong, however when the
developer makes the test pass they do so in a way
that is counter to the solution they’re seeking. It’s
fun to see a passing test suite in a solution that does
nothing at all like it’s supposed to.
Warning: This will stress folks’ creativity, and can
lead to much laughter!
