I've been to Portal about 150 times and just the other day was the first time that I actually completed it. I'm just curious to know how many other people have because it is such a difficult task. Have you or someone you know completed it? Remember, there's a difference between getting to Portal and ACTUALLY completing it (all 24 ramp shots + the disc shot for Super Jackpot).
Also, feel free to also discuss any strategies and big tips to get SOS lit, navigating through it, and completing Portal.
