Times Tables: 36 Cells
A trainer for ages 7–10. The times table is not a hundred problems but thirty-six: multiplying by 1 and by 10 is a rule, and swapping the factors removes half of the cells. The child sees this on a map that fills in pairs.

Thirty-six instead of a hundred
In a notebook the table looks like a hundred problems, and that is the first thing that makes a child give up. In fact multiplying by 1 and by 10 are rules, and 7 × 8 and 8 × 7 are the same cell. Thirty-six are left.
A new fact is shown before it is asked: rows of objects slide onto the board and a number grows beside them — eight, sixteen, twenty-four. Then the array turns a quarter turn, and it becomes obvious that 8 × 7 is the same handful. Only after that comes the question.
- From easy tables to hard ones
- The order is 2, 10, 5, 3, 4, 9, 6, 7, 8 — from doubling and “half of ten” to the hard core. By the time the seven table arrives, only two facts are left: the rest are already known thanks to swapping.
- Reviews on a schedule, not on a whim
- A learned fact comes back after one day, three days, a week, three weeks and two months — to check that it has not faded. A mistake sends it back to short intervals.
- First recognise, then recall
- At first the answer is chosen from four cards; once the fact is solid, it is typed on a keypad. Recalling is harder than recognising, and that is the point.
A mistake is an explanation, not a cross
After a wrong tap the correct card is not highlighted on its own. The
same array appears on the board with a one-line support trick:
8 × 7 — double it three times: 14, 28, 56
. The child finds and
taps the right answer himself: being shown an answer and recalling it
are different things, and only the second one teaches.
The same problem returns two to four tasks later in the same session. No red cross, no “wrong” across the screen, no lost points.
Timed mode — for the child who already knows it all
Three, five or ten minutes of problems in a row. A mistake costs two seconds: the correct answer lights up and stays on screen while the penalty runs — and those same two seconds are spent looking at it.
At the end: how many were solved, where he stumbled most often and whether his own record is beaten. The record is personal — no leaderboards, no comparing with a brother.
One question from a parent, one answer
A parent always asks the same thing: does he know it or not. The same map answers it, plus three numbers — learned, learning, forgotten. No percentages, no learning curves.
- Hard facts
- Where he is wrong most often and where he thinks longest — a list you can bring up at breakfast.
- Memory checks this week
- How many times something already considered learned was asked, and how many times he remembered it.
- “This table only”
- If tomorrow at school it is the six times table, you can ask the game to drill exactly that today.
- Screen time
- Minutes per day, both for the device and for each child. Plus a time limit with a goodbye phrase that the game enforces itself.
All of it behind an arithmetic lock: to enter the parents’ area you have to add two two-digit numbers.
What it looks like
A minute of play: a session with a mini-lesson, a mistake explained, an answer typed on the keypad, the timed mode and the parents’ screen.
What it costs
Nothing. The app is free in full, with no in-app purchases.
Works offline
The app requests no Android permissions at all and never goes online. Every child’s progress stays on the device.
What there is not and will not be
No rankings between children, no points, no lives, no timer during a session. The motivation is a map filling in, not the fear of losing a life. The studio’s rules are on the home page.

Frequently asked questions
What age is the game for?
Seven to ten — second and third grade. The child should be able to read the problem: “7 × 8 = ?” is shown in digits, not pictures.
Why thirty-six problems and not a hundred?
Multiplying by 1 and by 10 are rules, not facts to memorise. Swapping the factors removes half of what is left: 7 × 8 and 8 × 7 are the same cell. Thirty-six products remain, and the child sees this on a map that fills in pairs.
How long should a child practise each day?
One session is twelve tasks, about five minutes. More is not needed — the scheduled reviews do the rest. Five minutes every day beats forty minutes on Sundays.
Does it need the internet, and do you collect data?
No internet is needed: the app requests no Android permissions at all, including network access. No data is collected — no name, no age, no statistics. Child profiles and progress stay on the device.
Can several children use one tablet?
Yes, up to six profiles. Each has its own animal, an optional name and its own progress, so the app never mixes up who learned what. The profile is chosen at every launch, so a brother does not accidentally practise for his sister.
Are there ads or purchases?
Neither. The app is free in full: both modes, the parents’ area and all six profiles. No ads, no rewarded video, no subscription.
What happens when the child gets it wrong?
An array of objects appears on the board — those “seven rows of eight” — with a one-line support trick: “8 × 7 — double it three times: 14, 28, 56”. The correct card is not highlighted: the child finds and taps it himself. The same problem returns two to four tasks later.
How do I know the child has really learned it?
The parents’ area shows a map and three numbers: learned, learning, forgotten. “Learned” does not mean “answered once”; it means “remembered a week later and answered quickly”. A correct but slow answer does not raise the level — the child is still counting, not recalling.
Tomorrow school is testing the six times table. Can we drill just that?
Yes. The parents’ area has a “this table only” switch: the whole session is then built from that table, while the order inside stays the same — overdue first, then new, then familiar.
What is the timed mode?
A check for the child who thinks he already knows it all: three, five or ten minutes of problems in a row. A mistake costs two seconds — the correct answer lights up and stays on screen. At the end you see how many were solved and where he stumbled most. The record is personal and compared to no one.
