Fun but could be better
I've enjoyed this a lot. I only have three issues:
- The app only remembers the high scores for the Easy level.
- It's very easy to hit the wrong number by accident and be dinged for an error.
- Would like an "autocomplete" feature that automatically fills in any squares that are down to just one possibility. This would save a lot of tedium at the end of working the puzzle.
Other than that, it's very friendly to work. It takes a little bit of getting used to to switch between modes (solve/add possibilities/subtract possibilities), but once you do it seems very easy and natural.
With Family Sharing set up, up to six family members can use this app.
