Just a heads up: scroll down on the Dashboard until you see "Open Games" or just go to https://warlight.net/Multiplayer/OpenGames
Most of the games are actually free-to-play. You can get better at them over time, and then come in on the Coin Games (which have no gameplay differences whatsoever) and start winning coins there.
The new Dashboard design just makes it a bit tougher to realize that until you scroll down.
If you have AdBlock on your browser, click on the extension icon, "Block an Element," and then click on the "Promoted Games" table. Now, until you remove it, Coin Games aren't going to be on your Dashboard ever again and you can go straight to the free games.
EDIT: But be careful with AdBlock because WarLight gives you a points penalty for it. You want to disable it for the in-game ads themselves so it can't tell that you've got AdBlock working to fix your Dashboard.
