Neatly Squished
The brief
SQUISHDOKU: Place digits from 1-9 in every cell, so that no digit repeats in a row, column, or 3x3 region. The dashed lines indicate the boundaries of regions, and cells on the dashed lines are simultaneously part of the regions on both sides of the line.
EVEN PRODUCT DOMINOS: In this grid, any two adjacent cells multiply to give an even product.
KROPKI DOTS: Digits joined by a white dot are consecutive. Digits joined by a black dot are in a 1:2 ratio (one is double the other.) Not all dots are necessarily given.
