Great puzzle, disappears too quick – KenKen Classic Review

I just found this puzzle app and quickly learned how to play it. I love the app, but the nanosecond I complete a puzzle it disappears as “solved.” Sometimes I didn’t even realize this was my last move. I’d like to be able to look at my solved puzzle until I was ready to move on. I’d like to have a button to click to move forward.
