How the Arrow works
Arrow blocks can only be moved in the direction their arrow points.
It is one of the core obstacles you meet through the early and mid levels, usually alongside plain colored blocks and simple gates.
How to play around it
Check the arrow before planning a route, because an arrow block cannot travel against its own direction.
Like every obstacle in the game, the arrow never makes a level impossible. Every board can be finished without boosters, so if a route feels blocked, the answer is usually the order in which you clear the other colors, not the obstacle itself.
Where you meet it
The Arrow typically starts appearing around Level 6 and stays part of the rotation from that point on. Boards that feature it become more frequent as the level numbers climb.
See it in action on the Levels 1–25 walkthrough index, or browse every mechanic on the mechanics guide.
