Dictionaries

1. General word rules

These rules apply regardless of which dictionary you play with:

• Words must be 2–15 letters long.
• Every word you form on the board (including crosswords) is validated against the active dictionary.
• Validation is case-insensitive — tiles are uppercase but the dictionary lookup normalizes to lowercase.
• Invalid words incur a score and coin penalty.
• The dictionary is downloaded and cached locally so word checks work instantly, even offline in bot matches.
• You choose your dictionary when creating or joining a match. Both players in a match use the same dictionary.

2. Swedish

Swedish is built from two sources, both from Språkbanken (University of Gothenburg): the SAOL 14 faksimil (Svenska Akademiens ordlista) supplies the headwords, and SALDO Morfologi supplies the inflection paradigms. The standard list therefore includes inflected forms like springer and sprang, not just the base form springa.

Alfa Kraft is not affiliated with, endorsed by, or licensed by Svenska Akademien. The SAOL 14 headwords are taken from the SAOL 14 faksimil published by Språkbanken.

Word list details

• 481,796 words (base forms + inflections)
• 29 letters: A–Z plus Å, Ä, Ö
• Inflected forms expanded from SALDO Morfologi

Filtering rules

A word is kept only if it can actually be played on an Alfa Kraft board. Dropped:

• Proper nouns (egennamn) — Sverige, Anna, Volvo. Words that double as names stay: björn, ros, sten.
• Abbreviations (förkortningar) — osv., dvs., bl.a., in every word class.
• Multi-word entries (till exempel) and compound elements (hälso-, -skap) — neither is a single playable word.
• 2–15 letters from [a-zåäö] only; no spaces, digits, hyphens or other punctuation. Accented loanword letters fold to their Swedish equivalent.
• SALDO words with no SAOL 14 headword — SALDO supplies inflections for words SAOL lists, never new words of its own. abborrfisk is a SALDO lemma SAOL doesn’t carry, so it and its inflections are out.
• Duplicates collapse to a single entry.

For the sources, the full filtering rules, and in-browser search, see the dedicated Swedish word list page. Prefer SAOL headwords only? See Swedish (strict).

3. Swedish tile distribution

100 tiles total.

4. Swedish (strict)

The strict Swedish dictionary (Svenska (strikt)) is the SAOL 14 headword list on its own — every word Svenska Akademiens ordlista prints in bold, without the SALDO Morfologi inflection expansion the standard list adds. Base forms like springa are in, and so are the irregular forms SAOL prints as headwords in their own right (sprang, ögon, större, är) — but not the regular inflections SALDO generates (springer, katter, bilar). Every word here also appears in the standard list.

Word list details

• 111,285 headwords (bold SAOL 14 entries)
• 29 letters: A–Z plus Å, Ä, Ö
• Regular SALDO inflections excluded

The strict list uses the same tile distribution as the standard Swedish dictionary. For the source and in-browser search, see the dedicated Swedish (strict) word list page.

6. English — ENABLE1 word list

The English word list is ENABLE1, the public-domain list compiled by Mel Cooper (Mendel Leo Cooper, 1997). It is used as-is with no custom filtering pipeline.

Word list details

• 168,551 valid words
• 26 letters: A–Z
• Inflected forms included directly from ENABLE1

For the source attribution, see the dedicated English word list page. You can also search the full ENABLE1 list in browser on the English word search page — English entries do not include part-of-speech or inflection metadata, so search results stay as a simple word list.
