Allfactor is a puzzle that requires a combination of memory, logic and luck to solve. Simple to understand but can be hard to crack. Place diagonal lines on a grid at by clicking the blue and yellow blobs. Count vertically, for each column, the number of intersections of these diagonal lines. Get these column totals to match a target set of totals below and you have won!

Runs on windows 7, 8 and 10

A good strategy of beating the puzzle is to progress from right to left adding intersecting diagonals to get the total to match the target for that column. Once the total matches the target move to the left and repeat the process.

For each target total list there are two solutions.

If you really get stuck then press "h" for a hint but thats cheating...
