Arrowtix - Train Your Brain
Arrowtix - Train Your Brain
Arrowtix is a satisfying, brain-teasing puzzle game where your goal is to clear the board by sliding tangled arrows out of the grid. But there's a catch: each arrow can only move in the direction it's pointing, and its escape path must be completely empty! With 60 tricky levels spread across Normal, Medium, and Hard difficulties, Arrowtix will test your spatial logic and strategic thinking. Can you untangle the mess and clear the board?
Instructions:
Study the arrows and their directions. Select only arrows with an unobstructed path to the edge in the direction they point. Tap to slide them off. Blocked arrows cannot move; tapping them costs a life. Lose three lives and restart. The correct removal order is required so others become free. Use the hint icon to reveal a safe arrow when stuck.
