Explain it to me, like I'm thick please.
I gather it's some kind of way to save?
You buy them, and every month there is a draw to see who has won. And your money stays intact. You lose out to inflation if you don't win, but the odds are better than Lotto. If you get bored, you can cash them in for face value. When the results get published, it's a nice buzz, as it's gambling, but you keep your stake.
My wins over the past 5 years have been : 25 175 50 25 50 25 75 75 25 75 125 25 25 75 50 50 25 25 25 150 25 25 100 25 50 50 75 75 75 75 100 75 25 175 75 25 150 50 25 25 250 175 75 100 50 75 175 50 175 275 300 75 550 125 250 250 375 50 50 75 100 125 250 50

Was looking on MSE, and it basically suggests you need to invest a lot to see any benefit, and a saving account is better?
When banks were giving zero (or almost) interest, they were better than banks. But the recent rise in deposit rates have skewed things towards Savings Accounts. But, whilst the Bank of England has kept rates frozen, my bank announced a big drop in saving rates, but NOT loan rates, So NS&I is more lucrative.
But have a look at the NS&I savings things, they can be better than banks.
