A minimum bet amount of 0.01 is now required (either BTC or points).

Can that be lowered, now considering the increased BTC/USD exchange
Additionally, could the default be lowered as well, from 0.1 BTC? At nearly $10 per spin, that's a little high.

Hello, the website was working for me earlier, but i clicked play, and it comes up as it normally does, but without the spin button. My account is [email protected]. Would appreciate a refund.
EDIT: Just noticed, looked at the bottom and saw "-0.01 BTC available for withdrawal". I have a screenshot of that message if necessary.

I then logout and login again but all my bitcoins had gone.
Something like this happened to me. There is no e-mail verification and what I learned is I had signed up initially where I had typo'd on my e-mail address. Then when I went to log in the second time, it was a completely different account, with zero balance.
Fortunately I was able to figure out my typo by trying common mistakes I've made before and sure enough one had my funds.
One way you are able to tell if this is what happened is to look at the history.

If you played previously and nothing shows now, then you are on a different account. If that is what happened, maybe coolidgecoin can help clue you in as to which e-mail address you might have used.

Hello
I deposit 0.03 on this game, wow 0.02 totally 0.05.
I then logout and login again but all my bitcoins had gone.
This does not seem a fair game to me.
Where did my coins go?

Hello Sanjay,
This game is quite addicting. I have an uncanny urge to look at advice animals though...
One very minor thing I noticed:
When playing with actual bitcoins, if there is no immediate combo available (i.e. one spin remaining with 2 spins blue, 1 green, and 1 red) the text overlay on the wheel says "Keep spinning! Or sign up and play for real bitcoin!". It doesn't affect gameplay, but I definitely hesitated the first time I saw it.
Correction: I just replicated the message after 2 spins.

Thanks for the feedback, tyrannis! I'll look into the messaging issue you mention.

Even though you cannot know that the games shown were actually played by other players, each individual player can be sure that his or her own games are correctly shown on that page. As such, if any player notices that his or her own games are not correctly shown, that player can raise a red flag and alert the community.
I think the point is that you could easily add in a bunch of imaginary winning games to make it look like on average the site is performing as advertised. Nobody could prove that the added games weren't real.
It's still interesting to see the list of recent games. I just don't think it really proves anything. (Not like your provably fair hashes do).
Ah, I see. Yep, you're right, I could be making up games in the log to make it look like people are winning (I'm not!).

- The expected value of Kingcoin has increased to be competitive with other games. It is now approximately 0.984.
That's excellent!
- Each game is logged in the database with more details (in case I have to process refunds)
I suppose that isn't really useful as I cannot verify that the plays that weren't mine were actually for other players, so it provides really no value for verification but it was interesting to see someone else's string of luck giving me hope that maybe, just maybe, the next string like that will be mine. :-)
[Edit: History is still there. I'm not sure how I didn't see it before.

Stephen, pardon me, I'm going to comment on your redacted (struck-out) text.
I believe the 100-game history is indeed useful.

Looks to me like you're just showing off that you hit the King slice. 
I've fixed the "disappearing button" issue.

Yeah, I was just showing off. Not only did I hit the king slice, but I hit it on my first game while playing for maximum stake...
As for the disappearing button, here's another one that needs fixing: when I run out of funds, the button vanishes:

I wonder why the king slice is yellow. Wouldn't it be better to make it some colour that's different than all the other slices?

No, really--thanks. Good feedback. I was going for the King slice to look like "gold," but you're right; it looks too close to yellow. I changed it to purple.

Thanks again, dooglus!

- The expected value of Kingcoin has increased to be competitive with other games. It is now approximately 0.984.
- Game parameters are as follows: Black slice is 16% of the wheel (used to be 15%), King slice is 1.3% of the wheel (used to not exist), and other slices are a minimum of 15% of the wheel (used to be 10%).
- The maximum number of spins per game is now 5.
- Each game is logged in the database with more details (in case I have to process refunds)
Nice changes.
I just played for quite a long time and was up most of the time. Only playing for play money, but it does seem like the house edge has got smaller.
At one point I got bored and decided to bet the whole lot on a single spin. It told me the max bet was 2 chips, but then I couldn't figure out how to spin after that. I can edit my bet size, but the spin button has vanished:

I think it could be fun if you did a type of freeroll thing. Make an account and if you get up to 50 (or however many) you get .1 chips to play with.
If you drop to -50 (or however many) it'll bump you back to zero.
This could keep people playing on the site longer and make them more likely to invest actual chips.
