As of level 1900 the 'easy' levels are almost always too difficult. After playing for days (weeks) the requirements change and the level is doable. I manage to finish the hard levels within a day, the 'easy' levels give soo much frustration that it is no longer fun to play.
1937: 16 moves to collect 12 black sheep, 200 crops (2x100) and 6 flowers... HOW?
