Make a page. Make a book. Print it, colour it, sell it.

Six kinds of activity page, generated on request. Puzzles are free for everybody; a book — cover, pages, answer key, one PDF — is what a membership buys.

Playable in the browser

A sudoku takes digits from the keyboard and checks itself. A word search finds words as you drag. A maze walks with the arrow keys. A coloring page fills with a click. Nothing to install, nothing to print first.

Print-ready, with the answers

Every page prints on A4 or Letter with real page geometry. Puzzles carry their solution; a book gathers the keys into their own section at the back.

Sell the book

A finished book can be listed on the Leumas app store as a digital product, reviewed by a person, and sold for tokens with a fifteen percent platform fee.
