Consistently generating unsolvable grids. About 50% of the time on Hard level. Each number ends up in one of each of a nine square location to have a solvable puzzle. But when new puzzle is started, if for example there are two 8’s in center squares, the puzzle cannot be solved. I check now before I start because it is extremely annoying to go all the way through up and then find out that you are not going to be able to finish it.
