# Marketplace Slots
All players can **simultaneously sell up 3 CAThletes and 3 items**. NFTs are put up for sale via special slots, and once a players runs out of spare slots, they *have to wait* for a sell to be completed or remove a currently selling NFT from the Marketplace in order to sell something else.
After a successful sell, a slot goes into a ***3-day cool-down*** and can’t be used again before it ends.
> *Cancelling sell doesn't trigger slot cooldown, and the slot will be available as soon as the NFT removed from marketplace gets back into your Collectibles.*
Starting update 1.9.14, high-ranking players can use **additional slots**:
* +1 slot for CAThletes and 1 for items becomes available for players at **rank 7 and 8** *(they have a total of 4 slots)*;
* Another +1 slot is available to players of **rank 9 and 10** *(they have 5 slots in total)*.
Extra slots available for Rank 7-8 and 9-10 players.
Since *rank is dynamic* and a player can both increase and decrease their rank, ***changes in a player's rank will affect the number of slots*** available to them.
Let's consider some examples.
**Example 1:**
A players was at rank 10 and could use 5 slots. They put 5 CAThletes up for sale, occupying all available slots.
One CAThlete was sold successfully, and the slot it was in is now in a 3-day cooldown. The players decided to remove the second CAThlete from sale, thus freeing up another slot (which is not in a cool-down). They now have 3 slots occupied, one in cooldown, and one ready to use.
The player's rank drops to 7, meaning they lose 1 of the additional slots.
The player attempts to list another CAThlete for sale, but fails: the ready-to-use extra slot has disappeared (NOT the one in cool-down), leaving the player with 3 occupied slots and 1 in cool-down.
**Example 2:**
A user of rank 7 listed a CAThlete *(screenshot 1 below*) for sale and then dropped to rank 5 before the CAThlete was sold. The CAThlete will remain in this slot until it is sold or removed from sale. In case of a successful sell, the slot goes into cool-down *(screenshot 2).* After the cooldown of the fourth slot ends, this fourth slot disappears because it is unavailable to users of rank 5.
*Please note that in the second example, the rank drop from 7 to 5 was made before the CAT was sold, leading to the slot remaining occupied despite the rank change.*
