Worduino is made and published by Techtoniks LLC, Florida, United States. We build playful software with thoughtful details: tactile tiles, a dedicated soundtrack and a fresh reason to spend a little time with words.

The Worduino experience brings together Techtoniks’ game design, interface and software, together with the production audio supplied for Worduino. Thank you to everyone who has played, tested accessibility, reported a bug or helped make the daily puzzle better.

Worduino’s English word list is derived from SCOWLv2 / the English Speller Database, with game-specific normalization and editorial overlays. Thank you to Kevin Atkinson and the upstream contributors. Their complete copyright notices and permission terms are reproduced in Open-source licenses. Including a spelling is a gameplay rule, not an endorsement of every meaning or use of that word.
