In testchamber #18, there is this room with turrets, a cube, the deadly water, the timed door that can close on you and a energy ball puzzle ALL IN ONE ROOM! I need help, please respond if you know how to complete this puzzle AS SOON AS POSSIBLE! I'm desperate!

I beat it with TIMING
Where are you stuck? Take out the turrets, go down where the button is. Put a portal next to a button and one where you came in. Press the button. Go through the portal and when the door stops moving put a portal there and run to the side. If you look down, there is a platform. Jump down and put a portal on it. Get the cube. Place on button. Yay.

just keep thinking, you'll eventually get the cake

Being a bit more specific about where you're stuck would be helpful. I found this particular section to be one of the most frustrating in the game, because the timing is quite finicky. Odds are, like me, you've already thought of the right solution and just can't get the timings down. In which case, I can only suggest practice.

The BIG TIP: Enter the room, run for cover to the left, and from there make the energy ball hit the turrets, one by one (make sure the ball follows the laser paths, or else it will just bounce). Don't worry about the timed moving wall, you'll open it later.

Oh, THAT one. I kept forgetting which portal I fired (duh)

I don't really mean to belittle your question, but why would you ask us to tell you the answer to a puzzle when the game is a PUZZLE game? Literally the entire point of the game is for you to figure this out on your own. I feel like cheating would take all of the fun out of it.

(For me, the two hardest levels were test chamber 15 (that was SO HARD) and the turret test chamber (16, I think) in advanced mode. That is just unbelievably difficult.)

I completed this level using what the developers called a "ninja solution"-a solution the game developers never intended to exist. Believe it or not, if you use my method there's actually some extra GLaDOS dialogue you wouldn't get otherwise. But it's pretty hard to explain.

(I also know how to get through the companion cube level using a "ninja solution". In short, the energy balls are an unnecessary distraction. It's doable in two portals, and it involves the Rat Man den.)

I want extra GLaDOS dialogue!! This is my favorite level in Portal, it is one of the hardest and I always feel so satisfied when I get through it. It is very frustrating though. I'm very good with levels where there's time to think and plan but when you have to do things very quickly and precisely, as in this one, I tend to panic which doesn't help at all. As others have said, you will figure it out and when you do you will be as amazed and frustrated as all the rest of us. :)

Hard to explain and too lazy to explain which is why I say this: Search up on youtube to see how its done :)

Thank you for your comments.

Now try ADVANCED test chamber 18. Holy crap, it is SO DIFFICULT.

Test Chamber 18, the bane of my Portalistic existence.


This chamber screams "TIMING" everywhere. Timing is key, but on this chamber the importance of timing is ungodly vital.

The turrets? Nah, they're piece of cake (no pun intended). There are over 9000 fun ways to get rid of them. The energy ball on the other side took me forever to decipher.

My hint on this one: First attract the energy ball to the proper path. THEN quickly activate that stupid switch for the door that protects the receiver. Don't attempt to do it backwards (as I stupidly did over 8997 times out of 9000), otherwise you will be stuck forever as that door remains open for like 3 seconds... but the energy ball is FAR SLOWER than that.

The rest of the chamber is a walk in the park. Don't forget to practice your double-portal-in-mid-air skills first.
