Each ball may move sideways or downwards (diagonally or straight) any number of times, but may NOT move upwards, on its journey. Balls may not enter any cell more than once. Balls may not enter a grey shaded cell or a "bumper" cell (given digit). Each ball must visit both of the "target" cages (shaded yellow) along the way. No path shares any cells, and while they may cross other paths diagonally, no path crosses itself. Box borders divide the BLUE path into segments with the same sum. Adjacent digits along the GREEN path must differ by at least 5. Digits along the RED path must be 5 or higher.
