Just witnessed an incredible win streak. This player deposited less than 0.05 and cashed out 1 btc as of this post.



 Roll Eyes

I added a section called "Notable Wins" on the main post. Congrats on being the first.

I would also like to have a "My Bets" tab next to the "Recent Bets" tab.

Yeah..id too like to know on how is it provably fair!

Great question.

The game board is decided when a bet is placed, before any pieces are scratched. After placing a bet to start the game, the long string of numbers that shows up underneath the scratch ticket represents mathematical proof of that.

That string is important because it is used in the randomization of the scratch ticket and the scratch ticket cannot be changed unless that string of numbers also changes. When a game is finished, that string becomes a link so that you can see all of the relevant numbers needed to independently verify the scratch ticket was not manipulated and that you received a fair game. You can plug those numbers into the source code linked below to check, using the exact method used on the site.

It's also important to realize that the website can't possibly know which order you will scratch, so proving that the scratch ticket didn't change mid-game is what makes it provably fair.

There is some information about it here: https://github.com/absolutebit/provably-fair/blob/master/README.md

lol, it happens because one of the X or BTC symbols has not been clicked according to the server. click just one in a second or so. Don't be in a hurry and it won't occur again.

Anyway, I think admin has patched it now.

Just made a few more changes, it should be completely fixed now.

only 8 x's and i already lost

sometimes i win even i hit 9 x's first before getting 6 "BTC Image"


Thank you for taking the time to report a bug. It's a known visual-only bug and a fix is being worked on. What happens is that a spot is scratched, the website server records the scratch, but the image occasionally doesn't update to reflect it. It may be a caching issue or related to our DDOS protection. I will post an update when it's fixed, but keep in mind that the game is still completely fair, this is purely a front-end issue.

More thanks to ndnhc, he may have found the issue that was causing this. I patched it, but if you notice it still occurring, please let me know.

Website is back online and the bug has been patched. Many thanks to ndnhc for finding it and reporting it responsibly, you set a great example for the rest of the Bitcoin community.

Reporting a bug. Is there a bug bounty?

Website is temporarily offline while I investigate.

Funny lol! You processes the 0.1BTC cashout!

Bug report:
The player is allowed to set a negative bet. If won, I think the balance will be negative and if lost it will be positive.
I placed a -10BTC bet, lost and my balance went upto 10BTC instantly.

Solution:
Put a minimum bet like 10 satoshis or so and the problem is solved.

Indeed you did find a bug. I cancelled the other withdraw but keep the 0.1 BTC as a thank you.

Site looks good (except the bug GLBrim reported above). Do you have any plan to add a few more options just like in bitcoin-scratchticket.com?

Is that something you would like to see? I have been thinking about it. I'm also considering a progressive jackpot.

Provably Fair (Lottery Drawings)

AbsoluteBit lottery drawings use the Bitcoin blockchain to determine the winner of each game. Jackpot wins are also decided using the blockchain.

The block hash used to provide the final outcome of each game is 144 blocks in the future. It's stripped of all non-numerical characters and parsed from right to left until an active player position from 0 to 9 is found, with 0 representing player position 10.

If the first 3 parsed numbers are the same, that player wins the jackpot.

Provably Fair (Scratch Tickets)

The game board is decided when a bet is placed, before any pieces are scratched. After placing a bet to start the game, the long string of numbers that shows up underneath the scratch ticket represents mathematical proof of that.

That string is important because it is used in the randomization of the scratch ticket and the scratch ticket cannot be changed unless that string of numbers also changes. When a game is finished, that string becomes a link so that you can see all of the relevant numbers needed to independently verify the scratch ticket was not manipulated and that you received a fair game.

The website can't possibly know which order you will scratch, so proving that the scratch ticket didn't change mid-game is what makes it provably fair.

You control the outcome (Scratch Tickets)

Most Bitcoin games don't give the player much control over the outcome, it's decided through a random number, but AbsoluteBit is different. The scratch ticket is randomized, but the scratch order (every spot) is decided by the player, creating a large source of semi-randomness based on the players own decisions/intuition. This is also why every ticket is a possible winner– computer generated random numbers don't have the final say whether you win or lose.
