Do you think the 4 influence tracks are too FIDDLY? Do you have big fat sausage fingers? Well then, this is for YOU!
These are simple replacements -- print them, cut them apart if you like, and place them on/near the board (feel free to cover the original influence tracks). They are simple 4x9 grids (similar to the time grid in Tinners' Trail); instead of physically stacking those little discs on top of one other, just put them in a higher box of the grid! When you move to an empty column, put your disc at the bottom of the column -- voila presto snapo it's so easy!
