This deceptively-simple puzzle, created by Jai Kobayaashi Gomer of Kobayaashi Studios, has been called the "espresso of puzzles". It is "an intense shot of intelligent puzzling in a compact form".

The objective is simple - fill a 3x3 grid with the numbers 1 to 9, so that the number in each circular node is equal to the sum of the four surrounding spaces.

This is a puzzle for all ages!
