Color Block Jam Obstacles Guide: Arrow, Ice, Chain, and More

Read the constraint, not just the color

The official obstacle glossary lists arrow, layer, ice, star, combined, chained, door, bomb, rope, colorful path, crate, barrier, and many other mechanics. The useful question is always: what condition releases this object, and what move might accidentally prevent it?

A compact lookup table

Signal	What to check first
Arrow	The indicated direction and available lane
Ice	How many other blocks must clear
Chain	Which key blocks unlock it
Rope	The matching scissors color
Door	Whether its state changes after a clear
Bomb/Dynamite	The move limit before failure

How should you use a guide?

Use the glossary to name what you see, then use a complete level guide only after the opening board matches. A correct obstacle name does not prove that two layouts share the same solution.
