I think the only way to bet in game parlays is to make all your easily attainable . For example if you are picking a under on the total score of the game dont pick under 4 runs, pick under 12 runs..yes theres alot more juice on the under 12, but its easily attainable. Then if you want to get better odds in your favor just add another attainable bet...i have been doing ok at it...but lets be really your not going to win um all when your doing 5,6,7 leg parlays..
