Everything that can happen to a tile.

No hidden mechanics. Every number on this page is imported from the same code the checkout charges against, so it cannot drift from what actually happens.

How it works

  1. 01

    Pick an element

    Any of the 118. Gold if you are fast, Copper if you are sentimental, Argon if you think noble gases are funny.

  2. 02

    Paste your store link

    Your icon, name and rating come straight from the store listing, so there is nothing to upload.

  3. 03

    Pay the price on the tile

    Your app sits there with a link to your store page until somebody pays more to take it.

Board laws

RANK = DOLLARS PAID
The one rule. No code, giveaway or trick ever shows a standing that was not paid for.
SYNTHETICS DECAY
Rf to Og are always $0 to claim and never for sale. They expire in real half life order, and Oganesson only gets a day.
NO WAITING
Paid tiles can be taken back the same minute. Only $0 opening claims get a 24-hour head start.
HARD CEILING
$2,000 freezes a tile forever. Nobody can outbid it after that.

The shiny tiles are the premium ones. Every element sits exactly where the real periodic table puts it, so if you remember any chemistry at all you already know your way around.
