- Make at least 2 or 3 odd numbers per key. - Do not put more than 3 numbers per column. - Do not put more than 2 numbers by diagonal. - Do not put more than 3 numbers for each decade (01a10, 11a20, 21a30, 31a40, 41a50) - Do not put more than 2 numbers per line - Do not put more than 2 endings for the same key - Place a maximum of 2 numbers followed, only one key. - The sum of each key should provide between 120 and 150. Similarly a study for the sums of 5 numbers, also decided to analyze a study for the even and odd numbers in order to draw some conclusions. In the next table, we randomly selected and the quantities that may exit the possible pairs (P) and odd (I). As the result of the sums, this also looks to have a similar distribution between the drawn and possible. However one notes a slight peak in the Keys with 1 pair - 4 keys in odd and 2 pairs - 3 odd, which means it can be much more profitable to play with more odd pairs. With this base of ideas, if we wait for luck can even opt for a key with only odd numbers. Since leaving more odd that the couple and with only 2 hits can I get a prize (if combined with star) so I can more easily get small prizes, because we would spend playing with only 25 numbers (odd) instead of 50 numbers (odd and even). Of course, if the objective is to set the numbers 5, this method requires knowledge expect, since only until the last draw out a key four times with odd numbers 5 ... It was enough to choose 4 endings and 4 diagonals in each set of diagonals (1-48 and 6-49) to reach a final result of 9 numbers, and repair, as in other contests, the stars sufficed only choose 2 diagonals in each one of the diagonals (1-9 and 3-7) to reach the winning pair.
