Number Ninja
Play Number Ninja free online. Sums float up in bubbles. Tap the right answer tile to pop each one before three escape. Adding, take-away and times tables.
How to Play Number Ninja
Sums float up the page in bubbles, like 7 + 5 or 9 - 3. At the bottom of the page are six answer tiles. Work out the answer to any bubble, then tap the tile with that number, and the bubble pops.
The tiles always hold the answer to every bubble on the page, mixed in with some near misses, like 11 or 13 when the answer is 12. When one answer matches more than one bubble, the bubble nearest the top line pops first.
Each popped bubble scores 10 points, plus a bonus for your streak of right answers in a row. Popping a bubble close to the top line earns a little extra for the close call. A wrong tile breaks your streak and pushes every bubble a little higher, so guessing does not pay.
If a bubble floats past the red dashed line at the top, that sum has escaped. Three escaped sums end the game. The game starts with adding, then brings in taking away, then times tables, and the bubbles rise faster as you go.
Controls

Tips and Tricks
- Answer the bubble nearest the top first. That is the one about to escape.
- Watch out for near misses. Check the sum again before you tap a tile that is one away.
- Keep your streak going. A long streak is worth almost three times as much per sum.
- For times tables, look for easy ones like 2, 5 and 10 to clear quickly.
