[XRP] [ANN] Rippleflip.com -Visual XRP betting game! [Provably Fair] Jackpot 17x

[Rippleflip.com]

A new Ripple betting game
Rippleflip.com

Bet between 1 and 2000 XRP to win up to 17x your bet! And it's provably fair, too!

The fairness is provided the following way:
We've generated a list of random SHA-256 checksums. We've SHA-256'd them again and published a list of them (available at http://www.rippleflip.com/secrets_hashes.txt). So each secret used by us has a corresponding key in the file we've published. When a bet is received, we look at the transaction hash and determine ten "coin flips" by looking at the final byte of SHA-256(your transaction hash + our secret at index (Ledger ID of your transaction + Flip #)). So there will be 10 coin flips each game, all being random and fair.
We use node.js as backend. We use ripple-lib to communicate with s1.ripple.com, the public rippled server. We monitor for incoming transactions at our game address - and we won't miss any even if our game server is down, because we will also look at the history since we were last up. This doesn't mean we're intending to have downtime, but in case downtime happens, it will not cause trouble - all bets will be handled. We also monitor for outgoing winnings payments. If - for some reason or another - the winning payment fails to confirm, we will try to send it again in next 15 minutes as long until it's done.

bump.

[Rippleflip.com]

Made some updates in the engine.

[Rippleflip.com]

Rippleflip is out of beta!

What did we do during beta phase?
We implemented automatic double-checking system for transactions.
We stress-tested the game with several hundred concurrently running games.
We fixed minor clientside bugs.

Good luck!

[Rippleflip.com]

We upped our limit from 1000 XRP to 2000 XRP. Have fun!

[NWO]

Sounds good dude. I'll check it out 

[Rippleflip.com]

We did some minor updates on the client-side.

Give us some feedback about the things you like and things you don't and perhaps we can fix it. Have fun!

[Rippleflip.com]

Bump! Also a little update: we're planning on starting our own rippled-node!

[Rippleflip.com]

Hi all!

We've slightly updated our gameserver. Now the "Recent Games" -tab shouldn't show the game more than once (even if the winning payment failed to send and has been resent). We also improved our methods to check if a winning payment has been sent.

Have fun with Rippleflip.com!

P.S. We're probably starting our own rippled-node, too!

yeah a bit of scam this is

I had 6 to 4  of one type, and got zip, but you sort of do count by two.

6 of one type should win some thing on 5 and 5 should get nothing

[wasserman99]

so people do not recommend this site? i have not tried it.

How exactly is our game "a bit of scam"? We are provably fair and been running our game for months. We also have the lowest house edge of the games I've seen that use XRP.

its the way the pics look.
see humans are wired to think

xxxxxooooo = no win = even

your ripple flip pic does not include these as "lose" its all win win win or at least 1/2
put lose and how in the pic



http://www.rippleflip.com/?this

in fact it quite misleading if not deceptive (s75 TPA), on how it works , it does not explicitly say how you loose, except that the edge is 1.85% which infers a loss

but the pic just show win, there is no combination shown to lose the lot. It is just implied.

please update
but
xxxxxxoooo= win
or
ooooxxxxx= win

but your system

is

xxxxxxoooo= loose
ooooooxxxx = loose

Thanks for your feedback!

We are not intending on changing our winnings structure for now but we will rethink about it.
We initially left out the losing combinations because well, it's "Winnings table". But, we now included the losing combinations in there, too!

Have fun!

Yes you want to do this as you would probably get sued at some point, as there is no explicit way to actually lose everything, under what is rippleflip and the game details link does not work how the game works

the comment "it was under winnings", is itslef actually under what is rippleflip, so that is a bit of a cop out.

You are probably open to suit for any losses to date as there is no losing combination on the site anywhere

Well... Isn't it very obvious that if you get a combination that isn't listed in the winnings table, you lose? Have you played slot machines? Do they list all losing combinations, too?

Are you trying to troll me or what is this all about? It's hard for me to see you being serious on this one....

no its not obvious, see if there is a 1/2 next to a combination which at 1.85% could be all you need for the edge,

Being explicit will make everything transparent and keep lawyers away from your operations. Slots usually have lists of instructions about everything if you look, and are very highly regulated to ensure this.
