- Only 1 entry per user (you're free to include any number of pies on your picture);
.....
- No minimum entries for the contest to run;
These 2 rules are somewhat confusing, in my understanding they're contradictory. cmiiw
Also, are participants allowed to recreate work? (i hope not)
The first rule mean you can only create one pie to submit in the contest, but you can post the picture of your pie as much as you want.
The second one mean there's no minimum members need to join in order the contest to run, so let's say only 3 users join, three of them will have 100% guarantee get the prize. The same applies there's no limit people who want to join, if there's 100 peoples, 100 peoples are valid as long as they follow the rules.
Recreate work? I think even someone want to try to recreating a pie he found on a website, they can't copy paste 100% like the original work and there's will be an uniqueness from each participants.
