Your ticket to glory.

NOTE: As of Season 9, redeemed Generation Zero tickets will produce an already retired horse. These horses are eligible to breed but may no longer race.
Each ticket is redeemable for a Generation Zero in-game racehorse.
Generation Zero racehorse tickets are the offspring of the Studs and Fillies. They are essentially a coupon that can be redeemed for an NFT racehorse in Photo Finish ™ LIVE. Generation Zero refers to the fact that they are the first generation of racehorses to enter the ecosystem, setting the foundations for all future bloodlines.
Each ticket has a spread of Attributes and Preferences (link) based on the combination of Stud and Filly traits used to produce them. Generally – the rarer the combination of traits, the higher the grade of the offspring ticket.
Additionally, the PFP sires and dams used to create the tickets possessed traits in common between sexes – the more of these traits that matched (up to a perfect 5/5 trait match), the more bonus points the offspring received for their Attributes and Preferences.

An early version of the Breeding Tool – Note the ‘Matches’ field.
Attributes and Preferences both have a 3 unit max to boosting. This means within a grade – every Attribute (Start, Speed, Stam, etc.) on a ticket is between 0 and 3, likewise for Preferences.
