New Personal Best Score!Sharpen Mental Maths Skills with Number Ninja
A quick-fire arcade way to practise arithmetic, fractions and percentages.
The Number Ninja game is a timed maths arcade built for students who want to think faster. Answer quick-fire questions on multiplication, addition and subtraction, fractions and percentages, build combo streaks, earn XP and level up from Rookie Reflexes to Ninja Master. Every 10 answers you will face an โ๏ธ Boss Round with a slightly tougher question — hit it for a bonus while the main clock keeps running.
Combo streaks and progressive levels
Correct answers raise your combo: 3 in a row triggers a combo bonus, 5 is a Super Combo, 10 unlocks Ninja Mode and 20 is a Legendary Streak. Wrong answers reset the combo and consume one of three mistake markers, but the battle never ends early — you keep playing until time runs out. Session XP is earned only from genuine correct answers and disclosed bonus awards, and it drives climbing through six levels.
Built for the CBSE routine
Mental arithmetic and percentage skills are foundational across the CBSE Mathematics curriculum, from Class 6 Maths and Class 7 Maths to Class 8 Maths. Pair the game with our free CBSE study material or explore the other Maths games we have built for students.
