I thought, since I was home early, to go visit my parents, says my mom dinner is at 11:30, so I explained this game to her dinner is in 30 minutes now So I'm ready
Each round, an item will be auctioned to all of the contestants. This item may be positive, neutral, or negative. Some items will be displayed publicly at auction time, while others will remain covered. A schedule of auction items will be sent to a moderator in advance. The rounds will thus be structured a little differently than in the past five seasons. They will begin with the auction post, the bidding will last for ten minutes, and then the challenge will be posted fifteen minutes after the auction post. Bidding will be done publicly in the thread, in increments of $10. The person to bid the highest by the ten minute mark (from the initial auction post) will win the item!
At the start of this season, every contestant will be given $1,000 to spend at the auctions held throughout the season. They can also earn additional money by ranking in the top five contestants each round. Prizes will be as follows:
Today is a big prize, and I guess the winner won't be so secret, but it's still worth it. This prize grants you immunity for any round you wish, as specified in the OP rules. If you already won a secret spoon of safety, you cannot OWN this one; however, you can still bid on this, win it, and then gift it to someone else.
You may now start bidding. Only bids that are multiples of ten will be accepted. The highest bidder to post by 11:40 AM EST will win this item.
