For the 'Concrete Conquerors' event (found under Conqueror's Path), you need one Conqueror's Crest to enter, and the win structure is as follows:

  • 5 Wins: 92+ OVR Backyards Ballers Player
  • 4 Wins: 92 Backyard Ballers Player & 3000 coins
  • 3 Wins: 18000 coins
  • 2 Wins: 14000 coins
  • 1 Win: 11000 coins
  • 0 Wins: 100 coins

Five wins out of seven in one run (that you can interrupt) is what you need for the maximum rewards.

If you need another crest, there is a qualifying event where you need to win 7 out of 13 games. The other rewards for winning here are just coins, the total amount for seven wins adds up to just 2000. Yeah, I know.

Winning a combination of 15 Conqueror's Path games (qualifiers or main) also grants 1500 BB XP should you need it.

So, with this knowledge, you and anyone else who happens to view can decide for yourselves whether or not it's worth it. Given that the top reward is a 92+ BB player, I think it's worth it to try at least once. But that's just my opinion.

I did this last night. Got 5 wins in 5 and was rewarded with 1 92 Card? That was it?

So the reward for 5 wins is worse than the reward for 4???

FWIW it was a boring slog and totally not worth it.
