Bitcoin Forum

Hey Everybody,
 
We recently created an bitcoin lottery game called BitKong.me (http://BitKong.me) that works like real printed ticket.
 
We invite you to participate in beta testing and help us revealing issues in the game.
 
We did everything to make it fresh :)
 
Provability fair system will insure that everything is fair and clean.
 
No registration required, at the moment works with Bitcoin Testnet.
 
Here where you can get test bitcoins:

https://testnet.coinfaucet.eu/en/
 
P.S. Works great with Copay Testnet wallet!


Update:
Website now use real bitcoins, for beta period max bet limited to 250 bits, you can use any wallet, but make sure you have correct withdrawal address when using shared wallets.

It is just basic minesweeper game. It looks like there is no house edge at the moment?
I can agree that design is refreshing and provably fair is simple & easy.
I would like to choose between few 'ticket' variants.
I do not like an idea with the non-account system coins can be lost easily.

Hey joksim299 , thanks for your reply, we have house edge on withdrawal 1%, ticket variants are in our plans (3 column tickets and bigger value tickets), you wont lose coins because after 12 hours of inactivity coins will be returned to withdrawal address.

Tutorials are not ready yet, we will explain all in details after beta testing, when we put it live with real bitcoins.

Withdrawal address by default is our deposit address?
If we deposit using the exchange or other wallets where we do not have access to address form which was used to send, coins will be lost.

Love the design mate... good job :)

great web, but make the background stay it will better :)

and also with my deposit wallet i can send with my Blockchain.

Sadly would like to have seen your site but waiting for 4 minutes for your site to download on my phone is not acceptable in my case.

Sorry to hear that :(

Site is not small (~3MB) but usually loading only few seconds even on phones with 3G.
Can you please let me know model of your phone and connection speed you have used? We will try reproduce and fix issue.

Actually the size of BitKong.me is 4.3mB and loading time using broadband connection is 10+ seconds.
You should optimize it.

Your site is don't need to beta testing anymore right?

Maybe make it mobile friendly is good idea.

We need some btc to start trying on this loteries site?? Or just visit the site and then give some review here??

I have some problem verifying my bet, and I would like to know if I did something wrong in the process.

Hash: FA0CDD2ADE57124373BF56A3F13F60E1DB2201FDAA2FA0A4C3567583F3095AC1
Number: AA67C03CC2B48EC04C2C61D30068A46DC449D808D14736DAFC680A6C76492F20
Server Seed: 0111001111

The "Hash" is supposed to be calculated as SHA256(SHA256(Ticket Number + '-' + Server Seed)), but SHA256(AA67C03CC2B48EC04C2C61D30068A46DC449D808D14736DAFC680A6C76492F20-0111001111) is b765049511c7ee93d6ae9dcc9bd9125504cd90925f4ea04cff74b7767f1af76d and
SHA256(b765049511c7ee93d6ae9dcc9bd9125504cd90925f4ea04cff74b7767f1af76d) is 6ee32217ef397baeacc6f04a3024f4b06bac56777bf56bf93a5bc1c25c078fee

Hey, thanks for verifying bets!

After first SHA256 everything is right as you use UTF8 and result is b765049511c7ee93d6ae9dcc9bd9125504cd90925f4ea04cff74b7767f1af76d, but for second SHA256 no need to use UTF8 as there is no string separator, so input of second SHA256 will be just binary representation first hash.

You can try it in Bitcore playground http://bitcore.io/playground/#/units bitcore.crypto.Hash.sha256(bitcore.util.buffer.hexToBuffer('b765049511c7ee93d6ae9dcc9bd9125504cd90925f4ea04cff74b7767f1af76d'))

Amazing site! Even with those worthless coins I was enjoying the game! Sleek design and UX is beautifully done!Loving the game! Hope to play with real money soon!

Wanted to check out the website, but it's in maintenance mode.when it'll be online again?

Sorry I was busy last week and did not have the time to make an update on this. In fact, I received a PM from OP a week ago (just shortly after I raised the question).


And that gives me the exact same hash I received before playing the game. Another way to do that is to use http://www.fileformat.info/tool/hash.htm to do the first hash as string and do the second hash as binary data.


TL;DR: The site is provably fair. The bet verification can be done easily. The OP is helpful and answers my question promptly.

Website back again, with real bitcoins, it is beta though (max bet amount limited to 250 bits), but fully working and playable, we have some UI issues on the mobile version at the moment.

Design is awesome. btw will there be any promotion? i'm gonna play at your website later. :D

Is beta testing over or you still need people to test the site ? I see there some updates were announced today but still it is in beta version and many things to be done like UI issues for mobile users.Is there any reward for beta testers or it is voluntarily ?

seems to be a pretty interesting game cant wait to try it out with real money

Thanks for the update! So it looks like the site is worth trying.

As far as I understand the site works with Testnet Bitcoins which you can get free and with real bitcoins which you can deposit there right? So, no faucet with real bitcoins?
