okay i'm just trying to see if i can force this anyway but i can't i can't immediately see how to do that oh but ah here's a simple deduction though this this region here can't take that square because if it does now this cell here sees a NUMBER_TOKEN region and a NUMBER_TOKEN region you'd have to put NUMBER_TOKEN into it at least and you can't do that so that square is unshaded now now the sixth cell of this connected region is here or here so that's why it's got to be at least a six this is absolutely brilliant isn't it it's just brilliant ah now there's a virtual six seven eight nine quadruple in box five because whichever of these cells touches this square is going to have to be higher than it so it's going to be a seven eight or a nine so one of those two squares that one that one and that one create a quadruple
NO_SEGMENT_TOKEN
