Cards and the wildcard

Every week Crescent publishes a small set of cards. A card is a challenge: build an emulator, ship a library, make a bot! A project that picks a card and meets its requirement earns a multiplier on the number of stars it gets.

The wildcard

The wildcard has no requirement! If you would rather build something that is not on any card, take the wildcard. You still get pretty awesome prizes - the cards are for when you want to have fun and want to build something you haven’t built before!

I’m not sure if my project fits…

That’s quite alright! Pick the card that you think fits your project best. If we think that it doesn’t qualify, we’ll just set it to use the wildcard (or the right one!) instead. There’s no penalty for this!

…but please don’t select a completely unrelated card. It just wastes everyone’s time… :(
