Crossed Quest
One core verb: cross a new word onto a letter already on the board. Played freely it grows an endless shared universe; played in bounded rounds it makes finishable co-op puzzles. Every word you place is fossilized into the lattice — with your footprint.

A single infinite, persistent board. No pool, no walls, no fail state. Crossing-only growth keeps it one connected lattice forever. Pan, zoom, jump to the frontier, follow your trail.

Bounded board, a shared pool dealt to your hand — no one picks their own (the equalizer). Turn loop and collective scoring. Build a grid, then leave it for others to solve.

Type your own words and cross them freely on a bounded board — Universe-style. Build a themed crossword on any topic, then save it for others to solve.
