Every card has three sticker slots. Add new abilities to change what a card does and combine several mechanics on a single card. With the right combination of stickers, even an unassuming card can become the engine of your entire build.

Battles unfold on a 5×5 grid. Cards normally enter play at random, but you can choose two to appear first and get your build up and running. Adapt to where each card lands, connect their abilities, and turn every placement to your advantage.

If a battle doesn’t go your way, retry it with the same deck. Choose a different pair of opening cards, develop your board along a new path, and find the strategy that wins the fight.

A run spans four weeks. Each week gives you only seven days, and the Boss always arrives at the weekend.

Battling and resting are always available. At the start of each week, you can also choose one of several random events and make it a repeatable action for that week. New random events appear each day as well.

Each action consumes a different number of days. Spend the whole week fighting, hunt for new cards, modify the ones you already have, or simply sleep straight through to the weekend. How will you spend your week?

After you defeat the final Boss, your winning deck is sent to the Gaol, where it becomes a challenge for other players to overcome.

You can also enter the Gaol to face winning decks created by other players. Bring your own deck, find a way past their setup, and climb the leaderboard.
