In Gwent, you can increase your profile level after every game. A victory and a good score gives you an adequate amount of experience points, but it must be also stressed that a defeat and a draw also grants you some points.
Moreover, every 2 won rounds, the player can receive a random reward from the following pool:
- 15 Ore
- 15 Scraps
- 15 Meteorite Powder
- 1 random card - if you're lucky, you might even get an Epic one!
Apart from that, the player can receive an additional reward every 6th/18th/42nd round which will amount to 100, 75, and 50 ore, respectively. If you can manage to win 66 rounds, you also gain 50 Meteorite Powder.
Once 24 hours have passed since you won your first reward, a "New Day" starts in the game, and you can play for the daily rewards from scratch. To gain Ore quickly in Gwent, and thus get Kegs, it's a good idea to spare some time every day to win at least 6 rounds. In this way, you can buy at least 1 Keg and obtain new cards.
