INGRAIN is a daily word puzzle with a twist. Each day you get scrambled letters — sort them into two words, then find the one connecting word that links both (e.g. FIRE links FIREWORK + FIREPLACE). What makes it different: all 7 daily puzzles each week share one hidden theme. Guess the connector early in the week for bonus points — it rewards pattern recognition all week, not just one session. Free to play. Free account needed to submit and track scores.
