## What is Numbers War III?

Chalk squeaks, the numbers wiggle, and a plus sign is marching straight for your base. Welcome to Numbers War III, a tower defense game played entirely on a hand-drawn chalkboard.

Here is the whole idea in one line: a defender's damage equals its digit times 10. A 9 hits like a truck but costs a fortune, a 1 is your cheap little pea-shooter, and a 0 deals zero damage, which is exactly what makes it a perfect wall. Easy to learn, sneaky to master.

You drop number tiles (0 through 9) into the lanes and hold off an army of math symbols. Every enemy fights the way its symbol works. A × splits into clones. A ÷ cuts a defender's health in half. A ^ hops over one of your walls. An = rolls in behind armor. And at the very end, the ∞ boss waits for the few who make it that far.

Your money is Σ, little sums that fall onto the board. Tap to scoop them up, then spend on more digits. Line up two matching tiles to merge them, jump a tier, and double the power. The board keeps asking one quiet question: cheap and many, or few and mighty?

All 100 levels are drawn and tuned by hand, and the difficulty climbs the whole way. The opening boards are a friendly warm-up. The last stretch is a real wall, and only the sharpest players ever clear it.

Digits and symbols blink with tiny eyes, bounce on springy animations, and burst in a puff of chalk dust with sound that snaps. Great for kids sharpening mental math without it feeling like homework, and just as good for adults who love wringing every last drop out of a tactics puzzle. Family friendly, plays in landscape, and looks sharp on both iPhone and iPad.

Grab a piece of chalk. The symbols are already lining up.
