Domino Hunt is another classic genre we haven’t yet covered, and one of the oldest puzzle genres; it was patented in 1893 by Richard Osa, under the name "Dominosa Omnibus". Though the scanning can be a bit tedious, it has a surprising amount of depth, both in possible deductions and capacity for variations. After finding all the dominoes, you can set them up in a chain and watch them topple!

Rules: Divide the grid into two-cell regions. The pairs of numbers which must appear in the regions are given outside the grid, and must each be represented exactly once. (The numbers in the domino can be in either order.)

Interface Note: All the dominoes in the grid are given to the right. You can cross them out horizontally with the sub in edgesub mode, or switch to line mode. (Don’t cross them out with normal edges - it will interfere with answer check.)
