Rules

Tessellation
  • Fill each cell with a digit from 1-9.
  • Cells sharing an edge can't have the same digit.
  • Each horizontal row and vertical column contains a non-repeating consecutive set of digits (like 23456) in any order.
X-Sums
  • A clue outside the grid indicates the sum of the digits in the first X cells in the respective diagonal or row and column individually, where X is the digit in the first cell.
  • The values of a and b have to be determined.

Enjoy!

Neat puzzle! The values for a and b were a nice surprise. Second half was quite tricky but doable with patience.

It's always surprising how solvable these are. It feels like you should get stuck with about half the grid filled and the rest stuck in limbo, but no, the puzzle successfully continues.
