What is Number Ninja?
Number Ninja teaches the top numeric row of the keyboard (1 through 0) using a martial-arts theme. Numbers fly across the screen as targets, and the player chops each one by typing the matching key. Every star carries a single digit, and every six slices the level goes up and the stars fly in faster, which is the closest most typing games get to numeric data entry practice. It is the only game on the site focused entirely on the number row.

Recommended for These Grades
Why this grade range?
Kindergarten and 1st grade is when kids first learn to count and write numbers, and Number Ninja matches that timing for keyboard entry. Most typing curricula skip the number row entirely, which means kids eventually have to learn it the hard way for math homework or video game accounts. Number Ninja front-loads the practice in a low-stakes setting. The faster stars at higher levels prepare kids for spreadsheet-style entry, which becomes relevant in 3rd grade and beyond.
The number row is the part most typing programs skip. Number Ninja fills that gap, and the rest of the typing games kids play here cover the letter rows around it. It doubles as our dance mat typing level 4, with the number row added on top of capitals and punctuation.
Pro Tips for Number Ninja
-
1
Reach with the correct finger. 1 is left pinky, 5 is left index, 6 is right index, 0 is right pinky — same finger assignments as the home row.
-
2
Don't look at the keyboard. Numbers are far enough from home row that the visual cheat is tempting, but it ruins the muscle memory the game is trying to build.
-
3
Hop up and back — every star is one key. Reach from the home row to the digit and return before the next star arrives; that return trip is what builds speed.
-
4
Run it 10 minutes a week. Numbers are not a daily-practice need; once a week keeps the muscle memory without burning kids out.
