Mini pyramidWatch the answers climb
Warm-upRead each little T as a familiar sum. Put its answer above, then use that same number in the equation on the next row.
17 × 3 = 51
The top value does double duty: it solves this equation and becomes a clue for the one above it. That shared-number chain is the heart of Pyrimati.
Start with the clues you can solve right now.
↗Let each answer travel into the row above.
↗Follow the chain until every square is filled.
↗No sign-up, no timer, no calculator. Just three satisfying steps.
Read it the familiar way
Start at the bottom: what is 17 + 2?
The one ruleThe answer above becomes part of the next sum.
The early puzzles keep things simple. Later collections bring in roots, powers, and percentages to keep experienced puzzlers climbing.
17 + 2 = 19
19 − 16 = 3
17 × 3 = 51
16 ÷ 2 = 8
³√8 = 2
2⁴ = 16
4% of 50 = 2

Creator Colin Veitch was sketching on graph paper when a small stack of numbers began to connect. One equation became another, the shape grew, and Pyrimati was born.
Today every puzzle is uniquely generated to exercise mental arithmetic, logic, and that wonderful feeling when the whole route suddenly clicks.
