Well, the GeekGames were supposed to end at 2:00 PM (Melbourne Time) but it ended at 10:30 PM as soon as someone with the account named "IAmJoy". Am I sensing some partiality by SitePoint in their on contest? I was really excited for the results.
Actually, the games were meant to finish at 9PM Melbourne Time.
Check - http://games.sitepoint.com/terms . The points 3.1 & 3.2 clearly mention that it was meant to finish at 2PM.
Oh, there does seem to be an inconsistency in the terms They have links throughout "when the competition closes" which show a closing time of 9pm.
The forums aren't technically part of the Sitepoint business which was running the competition so you may get a better response sending your question to firstname.lastname@example.org.
I have emailed them about it. But is it mention anywhere on the website that it was supposed to end at 9PM? No where. Pretty disappointing from sitepoint.
