Tips and Tricks
The more games you have going on at the same time, the more gold and other bonuses that you can earn. It's simple as that.
Play tons of ranked matches at the same time to keep your game and earnings on the rise.
Use your earnings to go and buy more curses and more ships and make use of the upgrade tiles to power up your ship.
Try to use your cards in conjunction with each other whenever possible to achieve even better attack or defense results.
