If you are a newbie player then you can easily understand how minimum you can play and what is winning prize is on winning. In the 6 numbers draw, if a player plays a single number of ₤1 then after winning it can be claimed to the ₤7. So, players can check the other amount and check their prize amount by clicking the top menu.
There is a minimal difference in the prize of 7 numbers draw. In the 7 numbers draw, players have to select the booster balls also that is why their chance of winning is high but the prize amount is slightly low instead of the 6 numbers draw (not containing the booster ball).
Although there is no difference to play the 6 numbers and 7 numbers, the only difference is the booster ball. Most of the players don't use the booster balls but experienced players always use the booster number to increase their winning chances.
According to the survey, the players that use the booster balls can easily win the 49s numbers. So, it is up to the player's strategies and how they utilize them to achieve a winning amount.
