I noticed I was missing both the bronze and silver level map prizes. So I used a lot of my hammers and hammer boosts to go back to the bronze level. Once I got all 9 pieces, I was told the next egg I cracked would have my prize. Since I didn't wanna get sucked into another few rounds of bronze (if there were silver or gold eggs), I went back to level 9 (silver) to crack it open. Except once I did, the map showed up as completed. I went back to bronze and the map shows up as completed there too. But I don't have the silver prize yet. Am I only allowed to win one map prize per level per week?

Alright thanks. I guess I thought I could try for the silver level one too for this week but I guess I'll have to wait like 3 mos. for it to come back around? Also, with regards you saying "it will always be the lowest level that you need", could I have won the bronze prize by playing on a silver level? Because I've finished everything else in bronze and it's otherwise a waste of time and hammers. Thanks
