Rank is what you pay.

Stumblestack sends people through 4,264 tools one card at a time. They arrive curious and leave with a shortlist. A bid puts your tool in that flow more often, and on a public board while it's there.

What a bid actually buys

Weight in the deck

Your tool comes up more often when people stumble. Paid cards are capped at one in seven and always labelled, so the deck stays worth reading.

A place on the board

Public rank by total spend. Raising a listing only costs the difference, and one payment counts on the all-time, weekly and daily boards.

Clicks you can count

Outbound clicks are shown next to every listing, so you can see what the placement returned before deciding whether to defend it.

What it doesn't buy: the most liked board, which is thumbs only and not for sale. Money also can't override someone's interests — a paid card in a category a reader has thumbed down stays rare. You're buying a better chance among people plausibly interested, not attention from everyone.

The rules

• Rank is cumulative spend. Nothing else moves it. No editorial score, no review queue.
• New listings start at $10. Whole dollars only.
• Raising costs the difference. Already at $200 and want $500? You pay $300.
• Ties go to whoever got there first. Matching a total doesn't take the rank; taking #1 costs $5 over the leader.
• Bids are public and non-refundable. Someone paying more will rank above you, and that's the point.
• You can only bid on a listed tool, and only on categories it's genuinely in.
