About Number Pyramid: Mental Math
Just addition. And yet your whole mind is working.
Number Pyramid is a simple training app: add the numbers next to each other, row by row, until you reach the single number at the top. The only arithmetic is single-digit addition. Somehow it is still hard.
WHAT YOU ARE TRAINING IS MEMORY, NOT ARITHMETIC
Working memory is what holds something in mind while you do something else with it.
3 5 6 1 4
Starting from that bottom row, you work out 8, 11, 7 and 5 — and then you have to keep all four in your head while you start on the row above. Hold, calculate, hold again. That loop is what this app makes you repeat.
No paper, no pen. Build the pyramid in your head.
THREE STEPS
1. Look at the numbers along the bottom
2. Add each neighbouring pair and climb, row by row
3. Type the number at the top and tap Answer
The pyramid then opens one row at a time, so you can see exactly where you slipped.
EIGHT LEVELS, FROM 3 ROWS TO 10
Three rows takes a few seconds. Ten rows and the number of things you have to hold at once jumps. You cannot start at the top: three correct answers on a level unlocks the next one, so you climb a little above your current limit instead of drowning.
SMALL REWARDS FOR COMING BACK
- Your total correct answers and your record on each level are saved automatically
- Medals unlock as you hit milestones, and live on the Collection screen
- Seven of them, from First Pyramid to Ruler of the Pyramid
WHO IT IS FOR
- Anyone who wants to use their head in a spare minute
- People who never stuck with arithmetic worksheets but might stick with a game
- Anyone who feels that holding numbers in mind has got harder
- Parents looking for addition practice a child will not get bored of
- Anyone who wants something to play in silence
WHAT IS NOT IN IT
- No ads. Nothing interrupts you
- No in-app purchases. Every level opens through play alone
- No network. It works offline and in airplane mode
- No account, no sign-in, no personal data collected
- Choose a calculator keypad (789 on top) or a phone keypad (123 on top)
- Sound effects can be turned off
One puzzle a day still uses your head.

Latest updates
1.1
Number Pyramid is now available in your language.
The whole app has been translated, and the number of rows is now described in your own words. Everything else is unchanged: add the neighbouring numbers, climb to the top, from 3 rows up to 10.
Still no ads, no in-app purchases and no network of any kind.
