A strategy hybrid of deckbuilding, grid placement, and auto-battling, where every build phase is a chance to craft devastating synergies before your defenses are put to the test.

The strategy is in the setup.

The King Must Fall is a kingdom builder about planning, not panic.

Draft building cards. Expand the grid. Shape your economy. Stack synergies. Then trigger the wave and see whether your kingdom was truly built to last.

There is no timer forcing your hand.
No chaos until you allow it.
Only decisions.

Build With Purpose

Every card adds another piece to your kingdom.

Some buildings generate wealth.
Some train soldiers.
Some multiply the value of everything around them.
Some exist purely to turn a good build into a disgusting one.

A clean layout becomes a strong run.

Start the Wave

When you're satisfied with your setup, begin the attack.

Your troops and systems resolve combat automatically, transforming your careful planning into explosive battlefield results. Lines hold. Combos trigger. Fronts collapse. Kings fall.

Victory is not about fast hands.
It is about building something that works.

Grow Stronger, Risk Bigger

Every run offers new drafts, new combinations, and new chances to push your kingdom beyond what should be possible.

Play safe and scale steadily.
Or gamble everything on one absurd synergy and try to break the game before it breaks you.
