i found 2 silver chests today, opened, played the game and won but recieved no rewards from either of them. did you forget to include rewards or is this just for practice? i encounter some in dragonspyre a while back, i don't know what's up?
The silver chests you play a game ,something like connecting tubes I don't remember. If you win that game and connect all the pipes before the time is done you win prizes. Maybe the prizes are just coins. I never won those games. And this post should go to Haleston's Bug's not wizard city, if you want to get an exact the awnser. Hope this helped .
