How to Play Number Storm
Numbers rain down the screen in four lanes. Your job is to tap onlythe numbers that match today's rule — and resist tapping the ones that don't. Speed, accuracy, and focus all matter!
The Rules
- Even numbers — tap 2, 4, 6, 8, 10… Any number divisible by 2.
- Odd numbers — tap 1, 3, 5, 7, 9… Numbers not divisible by 2.
- Multiples of 3 — tap 3, 6, 9, 12, 15… Any number in the 3× table.
Today's rule changes each day. A new rule rotates in every 24 hours.
Scoring
- +10 points for each correct tap
- −5 points for tapping a wrong number (false positive)
- ×1.2 combo bonus for 5 correct taps in a row — your next 5 taps earn extra points
- Missing a qualifying number (letting it fall off) costs you nothing — but your accuracy suffers
Stars & Accuracy
- ⭐⭐⭐ — 90% accuracy or above
- ⭐⭐ — 70–89% accuracy
- ⭐ — 50–69% accuracy
Accuracy = correct taps ÷ (correct taps + wrong taps). Missing qualifiers doesn't hurt accuracy.
Adaptive Difficulty
Number Storm watches how you play and adjusts the speed and spawn rate after each round. Do well? Numbers fall faster and appear more often. Struggling? The game gives you more breathing room so you can build confidence.
Session Format
Each session is 8 rounds of 60 seconds each. After all 8 rounds your session results are reviewed and you receive personalised feedback to help you improve next time.
Curriculum Alignment
Number Storm is aligned with the primary school maths curriculum taught across Singapore, Malaysia, and Indonesia. Each rule targets a specific skill from the syllabus:
| Grade | Skills Covered |
|---|---|
| Grade 1–2 | Even & odd number recognition |
| Grade 3–4 | Multiplication tables (×2, ×3, ×5, ×10) |
| Grade 5–6 | Multiples of ×4, ×6, ×7, ×8, ×9 (coming in v2) |
Note: Aligned with primary school maths curriculum. More rule types (range, compound rules, dual active zones) will be added in future updates.
