Winning a game can be an immensely satisfying experience, and we understand that it'd be very frustrating if the round didn't seem to end, or if you didn't get your rewards.
There are a couple of possibilities, in this case.
There are two ways to achieve first place in a match - you can either do it alone, or as part of a coalition. The most important thing to keep in mind about this is that there are two victory thresholds as a result. A solo win requires less points than a coalition win, but can only be achieved by a single player.
Coalition points will not count toward a solo win, so always remember that a coalition needs to meet the coalition threshold, not the solo.
Alternatively, there may be a delay in your rewards, and so I'd recommend that you restart your app or refresh your browser, and you should see a change in your Goldmark after you've done so.
I hope this helps - but if there is still some confusion around your rewards, please don't hesitate to get in touch and let us know.
