allfactor play online

Allfactor is a number puzzle that requires a combination of memory, logic and luck to solve. Simple to understand but can be hard to crack.
Choose numbers 0 thru 3 to place on ten left and right lower diagonal button positions.
A number appears at each intersection of the diagonals which is the product of the two numbers.
Intersecting diagonal numbers sum upwards to give a running total, column by column.
Get each summed up column to match a target and you have won!
There are three levels of play: easy, medium and hard.
Think its easy... think again.
