Week 2
Day: 5
Game: Gates of Olympus
Bet multiplier: 72.1x

For example, on day 2 you get a multiplier of 545x which can be called the highest this week. Do I not need to post on day 3, day 4 and day 5? Or do I still have to post on the next 3 days to get 5 days of posting?
you can keep posting full for 5 days, maybe you get lucky in your game and get a high multiplier that puts you in second or third position. moreover, if someone gets a high multiplier on the first or second day, maybe on the third, fourth, or fifth day you get lucky and get a higher multiplier than that person, and make you rank first. the point is to stay optimistic that you can get a higher multiplier.
Or in another case, the week ends on Saturday. If I post today and that leaves me with only get "day-1" this week, does that mean I qualify for this challenge?
Thanks,
this should answer your question
In cases where users fail to publish 5 reports within 7 days (before the deadline on Saturday), their reports are carried over to the next week.
so if you post today, you are not eligible to compete this week because you failed to publish 5 reports. and your report today will be carried over to the next week.
