Objective
Clear the board by removing arrows in the correct order. Tapping a movable arrow removes the entire arrow piece with a short directional animation. Tapping a blocked arrow leaves it in place and gives subtle feedback so the puzzle stays readable rather than confusing.
One-arrow / one-arrowhead rule
Every piece contains one continuous arrow body and one final arrowhead only. Even when the body uses long runs, tight L-turns, reverse L-turns, U-turns, zigzags, stair-step paths, or winding curves, the arrow remains a single logical piece.
How blocking works
An arrow is removable only if the cells in front of its final arrowhead direction are empty all the way to the board boundary. Other arrow bodies may block this line. Removing one arrow can unlock several others, so the puzzle is about dependencies and sequencing rather than speed tapping.
Difficulty system
Difficulty increases through denser dependencies, misleading choices, longer bodies, more bends, and more intertwined removal order—not by using fake complexity or impossible layouts. Every published puzzle is automatically validated for arrow geometry, single-arrowhead integrity, legal first move availability, non-overlap, and full solvability before it becomes playable.
