Made a deposit. The pending deposit appeared, but the time was wrong (each minute actually took a few minutes) and, when the timer ended, the pending deposit disappeared without the money being added to my balance. There's been plenty of legit, working sites that use the Coindice script, but I'm guessing this isn't one of them.

Definitely tweaked data imo. Unless Op played himself and was betting live BTC there to test the system or something,
then is little chance that someone gambled that amount on fresh new Dice site. Explanation from Op?

So you confirm that this dice site is run by you? Is that correct?
The layout and design this dice site is almost the same as prime dice. It's much better if your site have it's own identity by having your own layout and design.

How about unique template and not the same crappy buggy site again?
