## Description

**Number Master: Run and Merge** is an engaging Chrome extension game where players swipe to move numbers and strategically absorb smaller numbers to grow bigger. Avoid bumping into larger numbers, which causes you to lose the number and restart. Navigate through challenges such as electric saws, bridges, and ditches. Once you reach the goal, face numerous walls that require breaking using your big numbers to uncover new worlds beyond.

This game blends strategic number merging with obstacle course elements, providing fun and challenging gameplay right in your browser. Perfect for those who enjoy casual puzzle and action games that stimulate thinking and quick decision making.
