Ratings and reviews

Love the app, very addictive. The only part that makes me want to uninstall it is that once completed, it seems to turn up the volume and blast a noisy ad, making it bad for night play as it wakes the wife.

I would like some way to distinguish between definite lines and possible lines. A different colour or thickness or dashed? Thanks. Otherwise very satisfying and addicting 🙂

Many puzzles have multiple solutions which should not be the case. Rest, the game is very good.
