Two games are built on these lists. Five letters takes its word of the day from them, and Word search builds its grids from the same words and checks every grid against every word the lists hold, so that no other word hides in it.

The English daily words in Five letters are drawn from the English Speller Database (ESDB, long known as SCOWL) — © 2000–2026 Kevin Atkinson, used under its MIT-style licence. The list is modified: narrowed to common five-letter base forms, curated by hand and shuffled once. Every accepted English guess comes from dwyl/english-words (the Unlicense), filtered to five letters.

The Polish words come from the word-game dictionary („Słownik do gier”) of SJP.PL, used under CC BY 4.0. That list is modified too: narrowed to five-letter words and filtered, with the daily pool hand-picked from it.

The Spanish words — the daily words and the accepted guesses alike — come from the hunspell-es dictionary of RLA-ES (Recursos Lingüísticos Abiertos del Español), version 2.9. It is offered under three licences (GPL 3+, LGPL 3+ and MPL 1.1); we use it under the Mozilla Public License 1.1. The list is modified: expanded to every five-letter form the dictionary accepts, written without accents (the ñ is kept), with the daily pool hand-picked from the dictionary’s headwords and shuffled once. The modified list stays under the MPL 1.1 and is available on request. The pick was made with the help of the FrequencyWords lists by Hermit Dave (the Spanish OpenSubtitles 2018 list), released under CC BY-SA 4.0, used only to rank the candidate words by how common they are. Nothing from that list is copied into the site, but the selection is derived from it, which is why it is named here.

The Hungarian words come from Magyar Ispell, the Hungarian hunspell dictionary written by László Németh and Ferenc Godó, version 1.9. It is offered under two licences (MPL 2.0 and LGPL 3+); we use it under the Mozilla Public License 2.0. The lists are modified: expanded to every five-letter form the dictionary accepts on its own — its compounds and its proper nouns left out — with the daily pool picked by hand from the dictionary’s base forms, read through by a native speaker and shuffled once. The accents stay: á é í ó ö ő ú ü ű are letters of the Hungarian alphabet, not marks on other letters. The modified lists stay under the MPL 2.0 and are available on request. The pick was made with the help of the same FrequencyWords lists by Hermit Dave (the Hungarian OpenSubtitles 2018 list), released under CC BY-SA 4.0, used only to rank the candidates.

The German words come from the German Wiktionary, written by its contributors, in the machine-readable extract published by kaikki.org (wiktextract, from the dump of 1 September 2026). Wiktionary’s text is offered under two licences (CC BY-SA 4.0 and the GFDL); we use it under CC BY-SA 4.0. The lists are modified: reduced to the five-letter German forms Wiktionary lists, inflections included — proper names, abbreviations, obsolete spellings and every word with ß left out — with the daily pool picked by hand from its base forms and shuffled once. Ä, ö and ü stay: they are letters with keys of their own. The modified lists stay under CC BY-SA 4.0 and are available on request. The pick leaned on two more lists: dys2p’s German word lists (de-7776), dedicated to the public domain under CC0, as a second opinion on which words everybody knows, and the same FrequencyWords lists by Hermit Dave (the German OpenSubtitles 2018 list), released under CC BY-SA 4.0, used only to rank the candidates.

The French words — the daily words and the accepted guesses alike — come from the French spelling dictionary of Grammalecte (“Dictionnaires orthographiques français”, the “classique” variant) by Olivier R., version 7.7, in the copy LibreOffice ships. It is offered under the Mozilla Public License 2.0. The list is modified: expanded to every five-letter form the dictionary accepts, written without accents or cedilla and with the ligatures spelled out (cœur becomes COEUR), with the daily pool hand-picked from the dictionary’s headwords and shuffled once. The modified list stays under the MPL 2.0 and is available on request. The pick was made with the help of the same FrequencyWords lists by Hermit Dave (the French OpenSubtitles 2018 list), released under CC BY-SA 4.0, used only to rank the candidates.

The Nonogram pictures come from game-icons.net, drawn by named authors and licensed under CC BY 3.0 — or from the editor here, drawn by people who offered them for the daily pool and credited by the name they gave, if they gave one. Each day’s picture carries its credit where it appears — on the finish card, in the archive and on the printed sheet; this page is the standing thank-you.

The Nonograms among the boards from the Beethoven film are our own drawings. Six of them make one picture between them, after the portrait of Ludwig van Beethoven by Joseph Karl Stieler (1820), which is in the public domain.

The map and the city boundary on the page about the Solar System at the scale of Zielona Góra come from OpenStreetMap, © OpenStreetMap contributors, available under the Open Database License (ODbL). The boundary is thinned to one point every fifty metres.
