In each voting round, you're allowed to vote for up to a certain number of levels. Vote for the levels that you want to stay in the contest, not for levels you want eliminated. You may vote for fewer levels than the permitted maximum. You may vote for your own levels.
It's not allowed to discuss the levels publicly on the forums during the voting phase, even if the level is not in the current round, or even between rounds.
You may discuss any level in private messages. You may discuss publicly off-site, e.g., you may post Youtube videos of your playthroughs, or discuss in IRC chat. Eliminated levels may be discussed anywhere, even publicly on the forums.
There'll be voteoffs within each design rule, to get down to one/two/three remaining levels per design rule.
If after the rule voteoff the number of remaining levels is >9, I will create 2 mixed groups semi-randomly out of the remaining levels to bring down the number even further. For all of this no tiebreakers are planned. After this, all qualifying levels will go into a final mixed voteoff.
Generally, the number of levels that qualify for the next round will be the same as each user's permitted vote maximum. I've decided to keep the percentages of "surviving" levels of the rule-voteoffs somewhat similar to give every rule a fair chance. Example: A rule with a 66% survival-rate and one with a 33% survival-rate for the mixed rounds doesn't seem that fair to me.
There's only a prize for the 1st place winner - of course, getting close to that still means you made a great level.
So... let the voting begin! Each round will be open for voting for 3 days, except the final which will be 4 days.
All levels are still avialable in the discussion topic:
