There is no way of knowing exactly how much you will win before the results are in, as it will depend on what the winning numbers are and what the dividend pays - both of which are unknown before the race has finished.
All First Fours will be paid on the dividend declared by VIC TAB.
If the First Four in the bet below pays $2000, our win will be calculated like this: $2000 x 166.66% = $3333.20
