Full-screen background & continuity

Image costs depend on size and the input frame.

Every completed turn is saved automatically, ready to pick up where you left off.

Opening Load does not interrupt generation. Loading another frame stops this turn. Leaving this page interrupts your view; generation may continue in the background.

Choose a world, then a frame. All completed frames are kept.

About Prairie Engine

The Prairie Engine takes one word and uses it as a seed to create a simulation. This world is in Pixel Theatre, our signature graphics style. The simulation remembers objects, stores prior interactions, and carries the world with each turn.
