Not even easy to get below 275 crops. This level not possible with this board layout and crop requirement. Max number of matches made was 23, so even with a plus two magic bean bonus, the requirement would still be over 220 required. I repeat, this level not possible with this board layout.
I am playing on an old laptop, through King. Farm heroes saga level 1971 has a target of 475 in 21 moves. This is not achievable with this board layout. I have only got below 200 on two occasions, in the last three weeks. No point in even attempting impossible targets. Time to finish with King maybe?
