Generate arithmetic pyramid worksheets with genuinely unique solutions, four difficulty levels, and one-click PDF export for puzzles and matching answers.
Each brick equals the sum of the two below it — pupils work backwards from the clues you choose to show. Four difficulty tiers (Easy through Very Hard)
The app uses genuine linear-algebra rank-testing to guarantee a unique solution, not just “probably fine.”
Five puzzle styles: standard integers, negative numbers, decimals, fractions, and two algebra modes (solve for x, or simultaneous equations in x and y).
Bulk-generate whole worksheet packs with matching answer booklets, both exported as print-ready A4 PDFs.
Fully offline once opened — runs in any browser, no installation, no account, no pupil data ever leaves the device.
