Slot Theory
SteamSlot Theory is a tower defense about building something beautiful and deeply wrong.
Every wave, you get 1 choice: a new tower, a modifier, or an upgrade. Build a 6-slot machine across 20 waves, commit to your picks, and watch the wave play out. No panic micro. No filler choices. Just decisions that stack.

Every wave, choose 1 of 5 cards:
Each pick permanently changes your run.
There’s no going back. No filler choices. Just decisions that stack.

No micro. No spam.

Every run becomes something distinct:
Your final build gets a name and a place on the leaderboard.
No two runs play the same.
