Color Block Jam Color-Switching Doors: Timing the Color Cycle

How does a Color-Switcher work?

Rollic describes it as a door that switches between two colors whenever a block passes through any gate. That means every gate action can affect future access, even when the block you just moved used a different route.

The right planning order

Write down the current door color, the color needed next, and the block that can trigger the state change. Then ask whether moving that block will strand another color. Preserve a staging square for the moment the door changes.

How do you use a video safely?

Match the door’s first color and first switch timing. If the cycle begins differently, the video is not a safe source for the current board. Use the mismatch guide to document the first changed state.
