Every Slot in your play does not pick a number at random: it starts from a base cloud containing every possible candidate and refines it in two stages. First, your Filters discard whatever does not fit your strategy and let through only the numbers that meet your rules.
Then those survivors are grouped into Patterns. The Natural pattern is more flexible and admits frequent combinations; the Strict pattern demands tighter conditions. Number by number and Slot by Slot, LotoLab turns a chaotic cloud into a set of candidates chosen with purpose.
