The Square of the Hippopotamus

(Published on 22. August 2023, 00:08 by cristophermoore)

This is a gift for Glum Hippo, who took the time to welcome me to this community!

In the center of the grid is a right triangle. On each side of the triangle is a 3x3 square of green cells, all or part of which is in the grid. The top square is tilted so that "adjacent" cells are separated by knights' moves, and its top-right corner is outside the grid. Cells in the bottom square are two steps apart, and its bottom row is outside the grid. (See thumbnail.)

The right triangle forms a cage in which digits cannot repeat.

The squares are all or partly magic. Within each square, any triple of green cells consisting of a horizontal, vertical, or diagonal line must sum to 15. This includes the two visible rows of the bottom square (i.e. r6c3,5,7 and r8c3,5,7), the sides of the tilted square r2c1-r4c2-r6c3 and r6c3-r5c5-r4c7, and its middle row, middle column, and its diagonal r2c1-r3c4-r4c7. There is no constraint on a triple that falls outside the grid. Digits MAY repeat in these triples if otherwise allowed.

Standard thermo and kropki rules apply: cells increase along thermometers, and cells with a dot between them are consecutive if the dot is white and in a 1:2 ratio if it is black.

Thanks for sharing. Had a great time once I realized that I had missed something obvious.

I enjoyed this one - not too difficult, really smooth solve, interesting logic and a few things to think about.
