Question 1

Why am I not winning even though all colors seem connected?

Accepted Answer

Victory requires three checks at once: endpoint connections, mechanism requirements (bridge/blend), and full coverage of all playable cells. Missing any one of these keeps the puzzle unsolved.

Question 2

Do walls and hollow cells need to be filled?

Accepted Answer

No. Walls (X) and hollow cells are non-playable. Only normal, bridge, and blend cells must be covered.

Question 3

Can I ignore a bridge cell?

Accepted Answer

If the puzzle marks that bridge with required colors, you cannot ignore it. Both required colors must pass through that bridge for a valid clear.

Question 4

How does a blend cell actually work?

Accepted Answer

The blend activates when its input color passes through it. After activation, the designated output color must also pass that same blend cell to satisfy the mechanism.

Question 5

Can two colors cross on any cell?

Accepted Answer

Only special overlap-capable cells (such as bridge, and blend under its valid color constraints) allow overlap. Normal cells do not.
