So just like 6/49 and all other lotteries there is no sure way to win, but many methods on how to get more numbers drawn bringing you closer to a possible win.
Here is some for Super 7
1-Method, the total sum of your 7 number should be
141 to 160 has been drawn 20.48%
161 to 180 has been drawn 21.01%
181 to 200 has been drawn 21.01%
2-Method--Odds vs Evens
Make
3 Odd and 4 Even 29% of the time
4 Odd and 3 Even 29% of the time
5 Odd and 2 Even 18% of the time

Hope this helps
