took a couple of tries but I got it

I solved it once, but couldn't solve it again, so I looked it up

Tried a few times after solving it the second time, finally solved it a third time. Think I can solve it on my own.

Read somewhere that Japanese employers use this? Man, I had an interview once with a logic puzzle (involving NAND gates I think). Uh... I didn't get the job!

Figured it out by yelling and cursing at the screen It actually made me focus more after the headache went away.
