if your mind is blank which is head from the three numbers you have chosen...just try this:
if todays date is 30...your choice for the head starts with zero (last digit for 30) and end at the 5th number:
0 1 2 3 4 5 so if any of these numbers are present make it as your no. post.
Example my number combination is 491.....my straight bet are two: 149 194.....bet big on these and also safer to bet small amounts on the box combination.
if todays date is 2 then start with 2 up to the 5th no.
good luck! happy winning!
