About Slot Theory

A roguelike tower defense where your build slowly becomes something you didn’t explicitly design.

Each wave gives you one irreversible decision. 
That decision doesn’t just make your defense stronger, it changes how it behaves over time.

You don’t build a loadout. You build something that emerges from your choices.

Towers and modifiers interact, interfere, and reshape each other across the run.

By the end of a run, your build has a distinct identity.

Some builds become efficient.
Some become chaotic.
Some collapse into overwhelming synergies you didn’t plan for.

Every run is a different machine formed from the same rules.
Seven Operators give each run a distinct starting identity before your first pick.

20 waves. One evolving decision chain.

Build it. Watch it take shape. Push it until it breaks.
