Zerdly Maths Adventure
Pick a picture and a school stage, from Kindergarten to Year 12, then play. Right answers power blasters, races, mazes, builds and a guardian battle at the end of every world. The maths never goes past the stage you chose.
No account, and the maths stays in your browser — more— less
This activity is for learning and practice. Anything it suggests is indicative only — it is not a formal assessment and not a substitute for a teacher or tutor.
Nothing you answer is sent to Zerdly. Progress is saved on this device only if you switch saving on, and you can delete it at any time. How Kids Maths handles data.
The stage you pick is a ceiling
Every topic in the game belongs to one school stage. A Year 3 learner only ever sees Year 3 maths and revision from earlier years. Difficulty still adapts: three right answers in a row on your own steps a topic up, and two misses step it down, but always inside that stage. Moving on to the next stage is a choice made on the stage map, never something the game does by itself.
Ten games, one learning loop
Power Blasters, Ratio Rally, Builder Island, Rune Maze, StarDock Defence, Creature Care Lab, Logic Switchboard, Skyhook Expedition, Sports Arena and the Boss Gauntlet all look and play differently, but they share the same rules. Nothing is timed. Hints and worked steps are free. A wrong answer is explained, often by naming the exact slip that produces it, and is followed by a fresh question of the same kind so the idea can be tried again straight away.
Mastery is earned with answers, not coins
XP and coins are rewards for playing, and they buy only cosmetics: colours, trails, vehicles and island decorations, at fixed prices, with no random boxes and nothing for sale. Whether a topic is "secure" is decided separately, from the answers alone: enough of them, across more than one day and more than one game, mostly right without help.
Senior maths
Years 11 and 12 differ by state and course, so senior learners pick a course first: Mathematics Essential, Applications, Methods or Specialist, named as they are in Western Australia. If you are not sure, the senior sampler offers a mix of general topics without claiming to cover any course.
Privacy
There are no accounts, names, ads, chat or tracking. Learners are "Learner 1", "Learner 2" and so on, with a picture. Progress stays in memory until a grown-up turns saving on in the game's Grown-ups area, and then it is kept only in this browser. Turning saving off deletes it. More detail is on the Kids Maths privacy page.
What this is, and is not
Practice and learning support. Topic placements are Zerdly's own judgement, informed by the shape of the Australian Curriculum and WA course names. They have not been reviewed by an educator, are not endorsed by any curriculum authority, and do not decide school placement or predict exam results.
