9 Kings Joker and Daily Mayhem: how to unlock both modes

Choose the unlock you are working toward

You want	Requirement	What to look for next
Joker / custom mode	Unlock the nine playable kings in the full game.	The Joker becomes available with custom deck and run rules.
Daily Mayhem	Finish all 81 base quests in Quest Mode on any difficulty.	The Daily Mayhem island becomes available in Quest Mode.

Check the playable roster first if the Joker is missing. A rival you’ve faced in a run can still be locked as a playable king. For Daily Mayhem, revisit the Quest Mode map and check for quests without a clear. The Conqueror achievement uses the same 81-quest requirement and gives Steam players another way to check the milestone.

Set up your first nine-card Joker deck

1. Choose a win condition before filling the deck. A front line, a damage source and a way to strengthen that damage make a useful first experiment. Add other cards that either give the front line time or make the damage plan work sooner.
2. Fill the nine-card deck using your available cards from the kings. Start with cards you recognize so you can tell whether the custom rules or the card choices changed the run.
3. Leave starting gold, lives and rerolls at their defaults for the first attempt. If you want to test a single rival, choose the enemy kings before entering. If random events obscure the comparison, the Joker settings allow you to disable them.
4. Change one rule for the second run. Try additional rerolls if the cards you need rarely appear. Try more starting gold if the problem is getting an early plan on the board. Keeping the deck fixed makes the effect of the rule easier to see.

Clear a stalled quest and check the Daily Mayhem island

Open an uncleared base quest and read its conditions before selecting your plan. Choose a difficulty you can finish consistently when your goal is the island. A quest that is unlocked but unfinished still needs a clear. Once you have cleared the base set, look for the newly available island.

Daily Mayhem gives you a new challenge each day with a supplied deck, decrees and special conditions. Read the conditions and cards before using the build you would normally choose. If your roster or island looks wrong after an update, confirm that you opened the full 1.0 game with the expected save before changing or deleting anything. Sad Socket recommends a new run after a patch when the old run was already underway. Check your unlocks on the selection screen before treating that as a reason to reset your profile.
