Moneypot.com - The ugliest website for me.
AFAIK moneypot is not a gambling site, it is a bitcoin gambling wallet. There are a lot of apps in moneypot, but not all of them are ugly. One example is betterbets.io, it is a great looking moneypot app even it is the best IMO.
panjul07 but more site use simple moneypot scrypt, whitout change and have really poor graphic, 3-6 month later born 1-2 dice site at week with basic moneypot scrypt.
Also, the Dust Dice game uses the moneypot API, and it is one of the best looking dice sites I've seen around.
I don't like the interface of Just-Dice, as I think it is too simple and I don't like the colors much, but I sometimes do play there as they are one of the most trusted dice sites.
I think the look of 999dice isn't that bad, but I don't like them as they aren't truly provably fair.
