FORTRESS FILLOMINO:
• Divide the grid into orthogonally connected regions and fill each cell with a number (not necessarily single-digit) showing the number of cells in the region to which it belongs;
• Each region must be either strictly larger than all of its orthogonal neighbours or strictly smaller than all of its orthogonal neighbours.

SPLIT PEAS:
• The sum of the numbers on a line between two peas (green circles) is a two-digit number, formed by the two digits in the peas, taken in either order.

N.B. Double-digit numbers need not be entered for solution check.

Relatively new to Fillomino and it took me a while, though I had just solved a 3* one earlier today and was feeling confident. May be hard to spot without experience. I rate this 2*.

Also the solution code was confusing since we were told to ignore double digit numbers, so the answer to my mind must be 1. For anyone else stuck, and without giving it away, count all threes in corners including all those part of double digit numbers.

This one took me 1 minute and 2 seconds to solve. Only took me that long because I initially missed one critical deduction.

Very nice puzzle, it was a minute well spent.

This is delightful, and a great introduction to the Fortress Fillomino concept
