Here is my design for Pachinko.
I want members to know Pachinko is a pinball game at a glance. So I placed an actual pinball on the right and the word "Pachinko" is made from tiny pinballs. I really like the idea of the game with an extra pinball which can win bonus for me too. I tried putting that in words using a large font size. Not sure I have worded it correctly, we can change that later.
I originally designed the sigs with your site's brown and green palette (
shown here), the brown didn't match up too well with the forum's blue/grey background, so I changed the sig colours to orange and green. Stands out more.
Hope you like them
