Word routes with consequence
Every banked word leaves a trail of evidence
Build across adjacent stones without reusing a tile. Lexicairn explains why a route is accepted, then separates tile, length, combo, morpheme, and rune points instead of hiding them behind one number.
Layered scoring
Long words matter, but focus roots, route streaks, high-value stones, and active runes create tactical alternatives.
Reproducible digs
Return to a campaign seed, open a challenge code, or play the board generated from the local date.
Local progress
History, best score, longest word, daily streak, settings, and expedition progress remain in the app container.
