How collecting works
Collecting happens in the COSMO app. This site doesn't sell anything: it shows what happens on the blockchain and helps you plan.
Buying
Each season's FCOs come out in editions: 101Z–108Z first, then 109Z–116Z, then 117Z–120Z. You choose a member and get one of the edition's numbers at random, so doubles are normal. Now and then a purchase also brings a rare PCO.
Grids → SCO
Collect one copy of every number of an edition, all of the same member (for example SeoAh 101Z to 108Z; the third edition has 4 numbers), and you can grid them in the app. The FCOs stay in your collection but are locked (they can't be sent or spun any more), and you get a Special objekt (SCO) of that member. Your collector page has a Grids & WCO tab that counts what you can grid and what's missing.
Spins
Got doubles? A spin sends an objekt you don't need to COSMO's spin machine and gives you a random objekt of the same season back: sometimes a rare SCO or PCO, sometimes nothing at all (about 1 spin in 10 breaks). Try it risk-free in the Spin simulator.
COMO and free Welcome class objekts
Minting objekts earns COMO, COSMO's voting token, and every SCO keeps paying 1 COMO a month (a PCO 2) on the day it was first minted. You spend COMO in Gravity votes (next chapter). Collecting a member's digital FCOs, SCOs and MCOs in a season also earns free Welcome class objekts (WCO) of that member in the next one.
Serials and sending
Each copy has a serial: #000001 is the first copy ever made, and low serials are popular. You can send a copy to any COSMO user, except Zero objekts and FCOs used in a grid.
