in row3, the 'x' values are starting to generate a pattern of their own, and that's gonna make things much harder on me.
Also what I like about this is things start to get harder gradually, there's levels to this shit.
after I can make a generalized formula for rows (if achievable), I will start to go column-wise.
Sorry if this doesn't help much, just ignore if you're way past this.
