How to Solve Color Block Jam Levels With Barriers

What is the barrier rule?

Rollic describes barriers as objects that open and close after each block is cleared. Therefore, the order of clears controls the route. The same move can be helpful when the barrier is open and harmful when it is closed.

A three-question method

Before clearing a block, ask: which barrier state will follow, which color needs that opening, and where can the next block wait safely? If you cannot answer all three, take a slower board scan instead of using the nearest clear.

Compare the barrier’s opening frame and first state change with the source. A different gate color or first move is enough to make the route unsafe. Use Wrong Level when the source diverges.
