As you'll see below, I played a £3 Cash Vault on May 3rd and wrote a post stating that I had won £6 on it.

After trying to cash in the card, I realise now that I made a mistake and this is not a winning card.

You'll see that I scratched off a vault and thought I had found the correct icon in the main game. The vault is actually on Lines 4/8. What I scratched off was a dial. In my defence, the pictures are somewhat similar and it is quite stupid to have a vault and a dial in the same game.
