How to unlock every king in 9 Kings

Only the King of Nothing is available in a new save. Each other king has a counter that keeps adding up across runs, and the king unlocks at the end of the run in which you pass it, whether or not you win. The Joker unlocks once all nine kings are available.

King of Time takes longest

“Play for 999 years” adds up the years of every run, won or lost. A run that ends in year 33 contributes 33 years, so the goal takes about 30 standard runs. Endless runs count every year past 33 as well: ten runs played to year 99 cover it.
