Not only is the Switch physical edition of Slay the Spire down to just $19.99 on Amazon, it qualifies for the buy 2, get 1 free promotion Amazon is running. I’ve been playing a lot of Slay the Spire on PC lately, and it’s quickly become my favorite roguelike deck-building game. Paying another $20 so I can play it anywhere on my Switch is an opportunity I jumped at.
