Arrow Repair
Change one arrow. Make the middle arrow and the majority follow their instructions.
Choose a tile to flip it. Choosing a different tile restores your previous choice. When you are ready, check both instructions. Take as long as you like.
Read both instructions
Choose one arrow to change.
The middle is tile 3. “At least three” means three, four or five arrows. More than one tile can sometimes solve a puzzle.
Check the two instructions separately
Read tile 3 first. Then count the arrows pointing in the requested majority direction. A repair can meet one instruction and miss the other. If the middle already points the right way, consider what changing an outside tile would do.
