Clarified rules: "ANY two lines...", i.e. the 1:2 ratio rule is true for any two lines that at any point share a 3x3 box. The sums refers to the sum of the entire renban.

I liked this idea. Smooth solve and not too difficult. Thank you for sharing.

Nice puzzle, fun concept. At first I was a bit confused because I read it that only 1 renban duo would have a 2:1 ratio.

@SKORP17 Whenever two renbans share a 3x3 (even if only one of the cells of one of the renbans shares the box with [part of] another renban) the sums of the complete renbans have a 2:1 ratio
