Quests are all about helping people. Sometimes, it's very clear how your cards can affect things. You should see a copy of your collection appear just above; simply click a card from your hand to play it. Clickable objects will usually cast a shadow when you mouse over them, so you can tell what's clickable and what's not. In this tutorial, you can always take a card back after playing it but before submitting it, simply by clicking it again. Other quests may not be so forgiving!

Way to go! Look at you, you've already helped someone! Sometimes, it won't be so clear what exactly you need to do. Feel free to play around and try different things; usually, there's no penalty for getting an input wrong. You can also always restart a quest using the button just under your hand if you think you don't have the cards you need to complete a quest.

Sometimes, you'll need to use multiple cards at once. Here, you can just load all the cards into your submission and submit them together.

Sometimes, it seems like what's going on doesn't relate to cards at all. But it does! Somehow.

There's not always exactly one way to solve a problem, but keep in mind that you only have so many cards, and you need to use them to complete all your quests. You can only use each card in one quest, so manage your resources wisely! (I hear a quest will uncomplete itself if you change the hand associated with the quest, so try not to do that...)
