What do you mean by dice game with low fee? Does it mean that the dice game will be an onchain game as well? Sorry to ask, but I have no idea about "low fee dice game" as what I know is that there is no fees on usual dice game.
If you are going to make onchain dice game then the result will be the same as what you have so far (low traffic). Dice game is popular as off chain game. Low bets is also usual thing in dice game because most dice sites lets their player to bet as low as possible (1 satoshi).
Sorry if I misunderstans your post.

No, I mean low fees in my old game on blockchain based.
Dice will be off chain I will try this type of game, may be I will get success.
1 satoshi? It's very low bet.

In his case, lightning network may help to run on chain dice game but IMO it could be a big problem instead of attractive thing as not all people understand about it. At least ut will be hard in the beginning, as it requires to learn about how lightning network works. And I'm sure most people will still stick on a usual dice game because of the simplicity.

Idea with Lightning Network is good. I think is not popular in this time. I will learn how works LN node, may be try switch game to LN.
You can test my dice game here http://oddevenbets.com/dice/
Thanks!

It is a great thing to have pretty basic dice game, it is really good progress to have some dice site here. But at first I have the connection time out problem. And after some period of time, I can access but it seems lag but there is standard graphic, I do not know what is the problem here. And btw may I know about the bankroll? Since on your odds and even bet game, you guys have pretty low max bet there, wondering about this dice game

I just tested your dice game. I like how the site looks and it's good that it's very easy to start playing without any registration process. I remember PrimeDice was starting like that, but they were attracting players with the faucet where the amount you can claim was rising with every bet made, if I'm not mistaken. Well, maybe it was rising every 10 bets, please correct me someone who knows exactly, but I remember how I was amazed by that, and you could claim the faucet every two minutes or so. But it was long time ago and maybe there were not as many abusers as today, so I don't blame you for setting minimal giveaway frequency to 3600 seconds. I think giving 50 sats per hour for trying the site is the right decision as of today.

I suggest you to add a button "1/2" next to "2x" because it is very convenient for players to have an opportunity to halve the bet amount right away, and I think that's why all the dice sites I know have that button. Another suggestion is to move the MAX button some place where it couldn't be hit by mistake or at least make a pop up window with a warning when the MAX button is hit. Also, you should maybe add a chatbox, dicers love chatting.

If the amount was bigger, I mean more than 100 times bigger, then theoretically the British police could help you. They could initiate a criminal case, get a warrant and then ask British Telecommunications to provide them with all the info they need on the thief. But I really doubt they would bother if $50 were stolen. I'm sorry for your loss, but it will hardly be refunded.

What did you mean by "hacked" btw? As I can see, Player_130 was winning 500 sats every minute or so, playing with 49.50% win chance. Are you sure he hacked your game? Because he could be just lucky, it's not so rare when people win $50 playing dice in one day.

This is not lucky..
I mean "hacked".. he does not made deposit. He use faucet 50 satoshi and placed bets higher then his deposit.
He won few bets only and balance was been 0 BUT HE WITHDRAW 0.008 BTC.

Last bets

I found this bug..

OK, I'm glad that he can't stole more
I fixed bugs and will be find new bugs..
Thanks.
