This is an idea I've been wanting to do for a while, combining "floating regions" (e.g. doublers) with sweeper rules. I initially tried to do a version with parity, but found entropy to have some fun logic in it. Enjoy!
Rules
Normal sudoku rules apply. Mark nine cells, one in each row, column, and box, containing the digits 1-9 once each.
Eight of the nine marked cells are "entropy sweeper" cells and count the number of cells in its 3x3 neighborhood that have the same entropy as it.
Digits belong to the same entropy when they are both low (123), middle (456) or high (789).
Lösungscode: Column 1

It gets harder as you gradually solve it.

For sweeper cells, does the count include itself or just it's neighbors?

@ohheyguysitsmax it counts itself as well
