A Tetris-inspired maths game where falling number blocks meet curriculum-aligned arithmetic, designed to make daily maths practice something kids actually ask to do.
Five worlds, six collectible monster buddies, four strategic power-ups, and 30+ levels of measurable progression. Difficulty adapts to the child's school year, distractor answers are pedagogically chosen so children learn from incorrect choices, and a Trainer mode introduces every mechanic without time pressure for first-time players.
For parents: no advertising, ever. No third-party analytics, no real names collected, no logins, no subscriptions. A one-time $5.99 unlock buys the whole thing for life. For schools, students join their actual school from a database of 8,000+ Australian schools, with year-level filtered leaderboards and Apple Volume Purchase Program support for bulk-licensing.


Built with four audiences in mind.
Every feature passes a four-way test: it has to delight the child, satisfy the teacher, reassure the parent, and work in a real classroom.
Play first, learn anyway.
- Tetris-style falling blocks: answer before they reach the top
- Six monster buddies to collect: puppy, kitten, dragon, penguin, bear, owl
- Four power-ups: Freeze, 50/50 Hint, Bomb, Extra Time
- Boss levels at the end of each world
- Coins earned through play unlock buddies, never sold for real money
Pedagogy under the play.
- Curriculum-aligned to AU Foundation–Year 6 outcomes
- Adaptive difficulty: tunes to the child's school year
- Distractor design: wrong answers are off-by-one, off-by-two, or operation confusion, so children learn from them
- Trainer mode introduces mechanics without time pressure
- Per-child stats: accuracy, streaks, best scores, level completion
Peace of mind, by design.

"MathStack was built with my 11-year-old daughter Alaska as the lead playtester and design consultant. Every level, every buddy, every power-up was approved by the toughest critic I know."
— Nicholas Gee, founder
