I don't really understand the mechanics of the game, but I guess there is a part of luck.
You can see the result in the leaderboard choosing the freeplay tab, indeed you didn't win and I won only 2 WAX:
Better luck next time I hope, you can play for free twice a week, Wednesday and Sunday.

Thank you. It's just there's no data to figure see how the battle went. I'll try again this week 😀
