Silly question?
On my other forum we now run a 'Free Bet'. Just pick a horse from each of the 4 races listed, and if they all win you get the value of the pool (as per T&C). Prize pool is £11 today, and increases daily if not won.

Doesn't matter if you know bugger all about racing, any 4 could win, and the odds are much easier than hitting 3 numbers on the lottery.

(You will need to register on the forum first, same as this one though).
