With a game made up of several lotto / Euromillions grids, we just have more chances of winning than alone with a grid and, a cost from only 0.01 €. My program makes sure to cover all the numbers in order to have maximum chances by avoiding duplicates.
In addition, you can be present on all the lottery draws for a cost much less than once in a while solo. In a group: 4 weeks of 3 lottery draws for 2.4 € (at 0.2 € / draw) VS solo: 1 draw per month for 2.2 €. Another very nice example: in a group, all the Euromillions games of the year for 0.01 € / draw or about 104 games for 1.04 € / year VS single-handed 1 game at 2.5 € for a single year. We see that with only 0.01 €, a EuroMillions part of the jackpot of 17 Million € minimum made up of a single grid, this gives a minimum gain in the event of a Jackpot of 68,000 €. The power of regrouping is here! More grids, all the draws = more chance of winning = more winning !!
