I don't trust.

Yes...but I can't do it at an intelligent time.

Do you have any tools available to you that let you execute code at a chosen time?

hah, I tried that multiple times, i get: You are not allowed to use call!

Yeah, it seems odd that the setPhoneCallback is forbidden in this level, because that solution would fit the sequence of levels very well. Luckily, there are other ways to cross the water, and some other commenters in the thread already hinted at them ;)

setPhoneCallback works perfectly for me in level 9 -- in fact, it's my intended solution: https://gist.github.com/anonymous/6e5606649b3cb0d60797

Seems this was a combination of my mistake and a bug that you might have fixed in the meantime. I intended to assign the player object to a variable player but made a mistake. The resulting error message was "player.setPhoneCallback not allowed" or something like that, but that was yesterday and with a different browser version (Firefox). Now when I tried to reproduce it, I get "player is not defined", which is much more helpful :)

I suspect that the GP ran into the same problem.

Don't forget about the function phone! :-)

I won all mine for $.01 by skipping the bid and just hitting buy it for a penny. Algorithm definitely needs work, heh.
