The Jockey Club on Saturday announced that it's boosting the prize fund for special Snowball draws in its Mark Six lottery, making the big-money jackpots more frequent and larger.

The club said it would start the new arrangements from Tuesday's draw, with more money being held back for the Snowball. It says the number of Snowball draws will rise from about seven per year to 12, while the top prize will be up to HK$100 million for some draws.

The club said in a statement: "The Snowball draw is a major attraction of the Mark Six."

The club said the minimum prize for regular draws would remain unchanged at HK$8 million, while other variable and fized prize allocations would also stay the same.

It noted that the majority of lottery revenue after payouts goes on benefitting the Hong Kong community, with 40 percent of lottery turnover going on taxes or into the lotteries fund.
