User blog comment:The Gatling Pea/Episode 68 holds level 1000?/@comment-24047760-20150516225941/@comment-25122955-20150517041837

Farm Heroes Saga is also one of the example of Blueeighthnote's comment.

Until Episode 34, there are 15 levels per episode. But, Episode 35 to 46 of the Farm Heroes Saga has 20 levels per episode. They changed 15 levels per episode since Episode 47, Lost Labyrinth came out.
