Hey there,

I’d like to introduce CoinNotify Dice, an in-blockchain fair dice game.

It’s a SatoshiDice style. We give you 10 different types of bet, depending on the odds and on the risk you want to take. You send an amount to a predefined address and you’ll have a transaction back. We aim for it to be a fast service. Our key differentiator is the house edge. Right now, and as a special opening promotion, we’re offering a 0.9%, for the first 5.000 bets; after that it will be increased to 1%. That means high returns, even higher than SatoshiDice’s.

  • 1CNDM2Nej4nKfhN5L5yc1jx7jvTKKedvd7   91.55% odds – 1.0824x prize
  • 1CNDvppKkSwWzXLq6UcndYNHvYffeYC4vL   85.45% odds – 1.1598x prize
  • 1CND6nSELhte5awGgSoU8NmFFHxxLCYA4L   73.24% odds – 1.3531x prize
  • 1CND7KNdZ485dSfFqiXoKdbaYKAdo4Ei4G   50% odds – 1.982x prize   
  • 1CNDiq6dmuFgtCDTFsPPAVUkjF9gd5MK1q   36.62% odds – 2.7062x prize
  • 1CNDWje6yNhzJRk1cjZYeViSDYSHGwNUUS   24.41% odds – 4.0593x prize
  • 1CNDW9Xd2APzgkcy6ZQnvhGFaKCNsNBjD2   18.31% odds – 5.4125x prize
  • 1CND88byDAFmt2biBeYHPxm3E5e34wJTAb   12.21% odds – 8.1192x prize
  • 1CNDC3nDSXpKMymQnDjZS7RLyBqokYqi46   4.58% odds – 21.6556x prize
  • 1CNDNBwKWFKgS61Htozrm9V7jVryyZSFQb   1.52% odds – 65.0102x prize   
  • 1CNDkpxc4Yy2MYaUvEzDQsogqw6c4BzEA5   0.3%   odds – 326.3577x prize

You can see the different bets on the website.

The minimum bet amount starts at 0.001 BTC.

As you may expect, CoinNotify Dice is a fair service, and, in fact, you have all the necessary data at your disposal to verify the bets.

And if you happen to have any problems, feel free to PM me, reply this post or send an email to the address stated on the site.

Update 1 (23:00 UTC 27 July): Reflected the new amounts and payment method. We dropped the 50% back and, instead, increased the returns.

My problem to it is that the house edge is pretty high (compared with other dice sites).

For the 50% bet, I have 50% to get 1.44x and 50% to get 0.5x back, and so the edge is 3% (before tx fees).
For 0.3% bet, I have 0.3% to get 155x and 99.7% to get 0.5x back, and so the edge is 3.65%.

Yeah, half your bet back is a silly gimmick, you are just betting half as much as you send in reality, and paying higher house edge for the privilege of having the half sent back to you?

Yes, it's true that the house edge is slightly higher than other sites, but as it's mentioned, this is to make up for the return of half of the bet.

I implemented the 50% back because I thought with this people would be more willing to take the risk of the bet, as they are sure they won't lose all the bet.

However, even if you get 50% back, the bet is computed with the total amount. For example:

I bet: 0.01 BTC to 50%
If I win, I get 0.01 x 1.44 = 0.0144 BTC
If I lose, I get 0.01 x 0.5  = 0.005 BTC

If I win, I get 0.01 x 1.44 = 0.0144 BTC
If I lose, I get 0.01 x 0.5  = 0.005 BTC

If I play on SD, I could bet half of my bitcoin on a 50% bet (x1.957 with 50%, x0.005 with 50%) and keep half of my bitcoin untouched.
Then, I would be able to get x1.4785 (x1.44 on your site) with 50% chance and x0.505 (x0.5 on your site) with 50% chance.

OP, it is good to see new gambling sites coming up, but to be competitive you need to set the edge lower. Smiley


BTW, don't get me wrong, I am not trying to discourage you or bash your site, I am just trying to help make it better. Smiley

Thanks @Soappa and everyone for commenting on the house edge and the 50% back. As I've found, instead of being a think that attracted to the game, it caused confusion and it made the service uncompetitive.

So, I've changed directions (and updated the first post).

We're offering higher returns (1% more than SatoshiDice; 54% more than the previous offering), however now we won't return 50% if you don't win the bet. Our house edge has been reduced to 0.9%, back from 2.75%.

For the posterity, the old Returns:

This amazing returns will be for the first 5.000 bets. After that, the house edge will be increased to 1%

Thanks for your feedback, and let me know your thoughts on the service.

Back on the webpage there was an issue that prevented some bets from showing up on the recent bets page, despite having been processed and paid out.

It has now been fixed.

Two bets placed during this period.
