Chaotic Sums
Rules:
Divide the grid into four regions of orthogonally connected cells, and fill the grid using the digits 1-9, so that no digit repeats in any row, column, or region.
A clue X outside the grid indicates the sum of all the digits that appear in its row or column before reaching the target digit X (starting from the end with the clue).
For any clue, the digits that sum to X must all be in one region, and the digit X itself must be in a different region.

Quite different from most puzzles without being hard. Very accessible way to get into weirder puzzles.
