Great game, but it will get frustrating. – Words of Wonders: Crossword Review

I’m finishing up puzzle 1879 (Poland). If you reach that level, you would have already played some tough to finish puzzles and rarely used words are more common at that point. I was stuck on a 5 letter word that started with the letter “C”. It turned out that word was CORNU. I had never heard or used that word in my life. Those rarely used words will come more frequently as the levels pass. I understand that the levels should get more difficult as the game progresses, but I still have 12 more countries to visit or at least (1440 more puzzles to solve) before finishing the game. I’ll never buy hints or spin the wheel to watch more ads, so it becomes a frustrating game as you progress thru the levels. I play the game to pass time and challenge my mind, trying to figure out words I’ve never used in my life may be the straw that breaks the camels back. I don’t know how long I’ll stay with this game, but it was great playing thru the first 21 countries!!
