HELP & FAQ
Everything you need to get your detectives up and running — accounts, logins, billing and troubleshooting.
💬Kiwi123 works in any web browser — nothing to install. From the home page, pick your child's year (or browse by topic), open a case, and start cracking clues. Not sure which year fits? Start with our curriculum guide or just try a case — if it's too easy or too hard, move a year up or down.
🕵️ How a case works, in 20 seconds
1. Read the clue. 2. Work out the maths and pick (or type) the answer. 3. Crack 5 clues to rule out a suspect. 4. The last suspect standing is the culprit — case closed, ka pai!
There are two kinds of login:
Forgot your password? Use the reset page and we'll email you a link.
No — the first mysteries in every year are open to everyone. Just pick a year on the home page and open a case. An account unlocks more and saves progress.
Each case has a line-up of suspects and a set of clues. Your child reads a clue, works out the maths, then picks (or types) the answer. Five correct answers rule out one suspect. When every clue is cracked, one suspect remains — the culprit!
Pick the year your child has just finished, or the one their class is working at. If it feels too easy or too hard, move up or down a year — year levels are a guide, not a test, and a bit of overlap between years is built into the curriculum.
A teacher or parent creates the account and adds children to a class. Each child logs in with the class code (like KIWI-5B), their first name, and a short secret word. No child email addresses — ever.
Every mystery in every year, saved progress and stars, student logins, and the teacher dashboard. Family covers one child at home; Classroom covers a class of up to 30 students.
Plans are billed per year or per NZ school term (4 terms a year), in NZ dollars, GST inclusive. You can cancel anytime from your account page and keep access until the end of the period you've paid for.
The catalogue is Number-first — counting, place value, the four operations, fractions, decimals, percentages, integers and ratio — because Number is the spine of the curriculum. Measurement, Geometry, Algebra and Statistics mysteries are on the way.
If a page looks odd after an update, a hard refresh usually fixes it (Ctrl + F5 on Windows, Cmd + Shift + R on Mac). If a mystery won't load on a school network, ask your IT team to allow kiwi123.co.nz — it's an education site. Still stuck? Email [email protected] and we'll sort it.
Every Kiwi123 mystery is a whodunit maths activity — read the clues, crack the numbers, catch the culprit. The first ones in every year are free.
