How to Play

Number Merge: The basics of growth

Your goal is to absorb green numbers that are smaller than yours to bulk up. Use your mouse or tap to slide left and right. Learning how to play Number Merge is fast, but the hitboxes on those red obstacles are unforgiving. If you touch a number bigger than you, it is game over.

Mastering Number Merge controls

The Number Merge controls are snappy, though the constant shifting can feel slippery on the later, faster sections. Do not swipe too hard or you will dodge right into a saw. A common mistake is trying to grab every green number you see, even when they lead you into a trap.

Winning at Number Merge

Once you hit the finish line, mash that wall to score big points. The final stretch is where the real math happens. Keep your number high and stay focused on the path ahead. It gets complicated when the saws start moving, so prepare to restart a few times.

Who Should Play Number Merge?
