Auction House

Players are able to buy and sell Cubies, Blueprints, Resources and NFTs using their Keys in the Auction House.

Unlocking the Auction House

Auction House before unlocking buying and selling options

Buys and sells are initially locked for each player.

  • After getting to HQ level 3 Buying in the Auction House can be unlocked by paying a one time fee of 1 Green Key.
  • After getting to HQ level 4 Selling in the Auction House can be unlocked by paying a one time fee of 1 Yellow Key.


  • While in the Auction House all bids are displayed as their value in Blue Keys.
  • The minimum bid increment is 5 Blue Keys of value.
  • The lowest price an item can be listed for is 2 Green Key
  • The winning bid goes to the seller in the highest key combo possible. If you see an item with a current bid of 195 Blue Key, you could become the high bidder by bidding 1 Yellow Key, 8Green Key and 20 Blue Key, or any combination that adds up to 200 Blue Key of value, but the seller would get 2 Yellow Key minus any fees if the auction ended after your bid.
    • If you later get outbid, your bid would be returned to your mailbox in it's original form.
  • There is a 10 minute delay between when auctions end and auction rewards are received by buyers/sellers.
  • White Keys and Crystal Keys cannot be used in the Auction House.

Buy Items - How to Buy Items in the Auction House

Auction House buying screen
  • Tabs of different items (Hottest, Cheapest/Most Expensive, Blueprints, Resources, Cubies, Skins, NFTs)
  • Item Rarity is denoted by banner color.
    • Yellow is Common
    • Red is Rare
    • Purple is Epic
    • Gold is Legendary
  • Auction Time
    • 3 Clocks: between 3 and 2 days left
    • 2 Clocks: between 2 and 1 day left
    • 1 Clock: less than 1 day left
  • Clicking on the blue keys will toggle between starting bid and highest bid. If the lower number shows 0 blue keys it means that nobody bid yet (the other value is the asking price)
  • After tapping the item you want to bid on, you can swipe your keys in before confirming your bid.
  • The minimum bid is 5 blue keys higher than the previous bid
  • If a bid is placed in the last 15 minutes of the auction, an additional 15 minutes gets added to the auction duration. This gets repeated until there are no more bids for 15 minutes, upon which the auction will end. For Desirable items, the Auction House can become a war of attrition, placing bids every 15 minutes until the other side gives up.
  • If you get outbid you will get a notification letting you know, and your bid in it's original form will be returned to your HQ mailbox. To have a good chance of winning auctions you should be near your HQ when it's about to end.

Sell Items - How to Sell Items in the Auction House

Auction House selling screen
  • Drag item(s) to conveyor belt to put them up for sale
  • For items that you have multiple of, the system will ask you to choose the quantity you want to list. (Be careful here, many people have accidentally listed way more than they originally intended, support cannot help you cancel an auction after you list it)
  • Drag each key type to pick your initial ask price. This will be displayed in the Auction House as it's blue key value.
    • This does not include the minimum increment, so expect a bid of at least 5 Blue Key more than what you ask here.
    • The minimum listing price is 2 Green Key
  • All items put for sale are on auction for 3 days
  • Highest bid after 3 days is the winner, auctions can be extended beyond this if there are bidders within the last 15 minutes.


There are two fees for seller:

  • A Green Key listing fee, paid upfront to encourage stacking items.
  • A 10% final sale price fee. If someone buys an item for 1750 blue keys worth of value, the seller will receive 1Red Key, 5Yellow Key, 7Green Key, and 5 Blue Key (1575 Blue Keys Value).
  • The Auction House final sale fee gets rounded up in favor of the Auction House. If an item sells for 101 keys, 10% fee would be 10.1 Keys, this gets rounded up to 11, netting the seller 90 keys of value, paid out as 9Green Key.
