Lotteries that end with fewer players provide better odds of winning, but also a lower than maximum payout. A full lottery of 10 players provides a 10% chance for each player to receive the maximum payout of 9.4x. In this case the odds of winning were 17% with a payout of 5.64x.
what will happen if there is only 2 player for that lottery? will the game still be play?

Fewer players provides better odds of winning, but a reduced payout. Two players would be a 50% chance of winning for each of them.
