Watch the deck, not the shop (Tips)
The single biggest win-rate jump in Slay the Spire: skip cards. A lean 15-20 card deck beats a fat 40-card deck almost every time — card removal at shops is the strongest purchase in the game.

No cheat codes exist — but seeds exist (Tips)
Slay the Spire has no cheat codes — but Custom Mode lets you set a run SEED, and daily climbs fix everyone's seed. Reproducible runs are the intended 'cheat' for streak hunters; watch top players' seeds on the leaderboard.

Save Scumming (Exploit)
If you make a mistake in combat, you can quit to the main menu and 'Abandon Run' is not required; simply 'Continue' to restart the current combat encounter from the beginning.
Open the game menu during any combat, select 'Save and Quit', then relaunch the run from the main menu to reset the fight.
Unlock All Characters (Save Edit) (Unlock All)
The local save file stores unlocked characters and ascension levels; editing the unlocks block grants all four characters plus The Watcher without the grind. Back up the file first — and note this is single-player only, so it can't spoil anyone else's run.
Locate your 'preferences' folder in the game's install directory and edit the 'STSUnlock' file to set all unlocked values to true.
