People in Newport will find out later how much of a share they have won of a £2 million lottery cash pot.
Organisers of the People's Postcode Lottery will be in the city centre along with ambassador and former Wales and British Lions International Scott Quinnell.
Aside from individuals who benefit from the scheme charities also get a 20 percent share of the money raised by the lottery.
Previous winners include a children's hospice in North Wales, which provides specialist nursing care and support to terminally ill young people. Ty Gobaith in Conwy, was awarded fifteen thousand pounds by the People's Postcode Trust in June after topping a public vote.
The sister of missing Manic Street Preacher Richey Edwards, who went missing in 1995, is also a supporter of the lottery scheme which has previously given money to charities like Missing people Wales which helps to re-unite lost people with their families.
Other charities who have already benefitted from the lottery include Wildlife Trusts Wales and Maggie's Cancer Caring Centres.
Scott Quinnell is from the People's Postcode Lottery. He says it's "wonderful" to see the smiles of the people who win.
