the rewards' limit for a game has been reached

tonight i read on the newspaper this message

Raggiunto il limite di premi per partita

Per vincere alcuni premi è necessario soddisfarne i requisiti entro la fine di una singola partita.

Questa partita ha raggiunto il giorno 45 e quindi il termine per soddisfare i requisiti fondamentali per vincere i premi succitati. In ogni caso, tutte le statistiche continueranno ad essere conteggiate per il tuo record personale, come di consueto.

my translation from italian:

the rewards' limit for a game has been reached. To win some rewards it is necessary to satisfy the requirements within the end od a single game. This game has reached day 45 that is the deadline to satisfy the fundamental requirements to win the aforementioned rewards.

Well , what does it mean ? What are the rewards we can't anymore win ? they weren't mentioned anywhere . I don't understand
