Five thousand boards, and a bot plays every one

A match-three level is easy to build and hard to judge. Give a board two moves too many and it is boring; two too few and it is unfair, and the player cannot tell which of those happened to them.

So nobody on the team decides. A bot plays every level thousands of times, and the move budget is settled at the point where that bot wins as often as the level's difficulty class says it should. Five thousand boards go through this, which is why none of them was designed by feel — and why there is no board in the game that cannot be solved.
