About Rainypad

Rainypad is an independent website of free printables: puzzles, mazes, worksheets, calendars, maps, crafts and coloring pages, plus tools that make new ones in your browser.

Every sheet is made by code and then checked by code before it is published. A sudoku is only published if it has exactly one solution. Every square of a maze can be reached, and from Hard upward a maze has exactly one route. A crown template is measured to fit the head size it states. A map label is checked to sit inside its own country. Coloring pages are checked for areas too thin to color. When a check fails, the sheet is not published; the lesson is written into the code so it cannot happen again.

Everything is free and needs no account. The tools work inside your browser, so a name you type or a photo you choose never leaves your device.

Where our sheets use other people's work, it is open-licensed or public domain and credited on the credits page.

Rainypad is built and maintained by Lucas Pradella, who writes the code that makes the sheets and the checks they have to pass.
