Slay The Spire is perhaps one of the best singleplayer card games on the market right now, and there's good reason why there's so many players playing, enjoying, and praising the game. Since it sends players to climb a seemingly infinite tower of horrors, an Endless Mode is practically a must.
Slay The Spire Endless Mode is an entirely optional mode of play that does require a few clicks and some experience playing the game, and in this article, we'll show you how to get it up and running properly.
If you're wondering how to play Endless Mode in Slay The Spire, worry not, because you're definitely not the only one. The mode is sort of hidden away behind a tad less inviting Custom Mode, and requires a bit of footwork to unlock.
Slay The Spire Custom Mode won't be unlocked until you successfully attain all three of the game's base characters, which will - in turn - require at least two full playthroughs of the game. This shouldn't take long, depending on how good you are at Slay The Spire. First you finish a single run with the Ironclad, then play the Daily Mode at least once. Once you've done both, you should have access to Custom.
As depicted above, Custom provides an absolute plethora of customisation options, one of which is - you've guessed it - Endless. There's lots more to fiddle with, also, but keep in mind that playing Custom Mode will disable your achievements, which may or may not be a deal-breaker depending on your preferences.
