There are for types of packs: Common, Rare, Epic, and Legendary. Each of them has a different distribution of probabilities for the rarity of the resulting G-Bot:
G-Bot Packs Rarity Probabilities
The rare the pack is, the higher the rarity of the resulting G-Bot. As a note, the Ultimate rarity can only be achieved through breeding G-Bots, coming up later this year.
Are packs open individually or do they open all at the same time?
You can open your packs one by one, and you can also decide to leave them unopened and come at some other time.
How many G-Bots are in one pack?
Do I need tokens to open the packs?
Yes, you need a bit of MATIC to cover the gas fees
How do I disconnect many G-Bots are in one pack?
The only proper way of how to disconnect a wallet from a DAP is to go to your wallet extension and disconnect it manually - which will truly cut off the connection and the trust you gave us by connecting your wallet. From that on, we don’t have access.
