Development Update

We are working on getting the game and our systems back up and running ASAP. We too are currently experiencing issues with Ethereum node syncs, but once these issues have been sorted we will be back up and running. We apologize for the delays. We know you are all eager to see us back online, we are too. Massive record spikes in transactions recently across the network are hampering our ability to get back up and running as quickly and smoothly as we would like to There is currently a 2 hour backlog of transactions due to the BAT ICO. 24 seconds of token sale, followed by a 3+ hour backlog of failed transactions. We will keep you updated.

Game temporarily paused – Ethereum network under heavy load due to MYST token sale.

There were 2600txs queued up on the ethereum network. We are working to resolve the game back to normal status once the network has cleared. For now, the game is paused until the txs queue is cleared. Any unprocessed games will be processed ASAP. Thank you for your patience.

*UPDATE: Network wide transaction backlog has been cleared. We await our oracle to come back online. We will keep you updated accordingly. We apologize for the recent delays.

*UPDATE 2: We will go live once the service normalizes and all issues are resolved 100%. We will provide updates accordingly.

Etheroll is back online

Thank you for your patience. A couple of items;

  • For now we only fully support Mist browser. Do not use Metamask + Chrome. It is important that you follow the instructions on our ‘How to Play’ tab.
  • Considering the recent rise in ether we have reduced the minimum bet to 0.1 ether.
  • If you are still seeing ‘offline – maintenance’ when you load the page, right click the page loaded in Mist and select inspect element > Network > check the box ‘disable cache’, then right click the page again and select ‘Reload’. Mist is very aggressive with caching, but this should solve any caching issues you may be experiencing.
  • The bankroll has been loaded with the funds from the discontinued contract and we start from where we previously left off.
  • New contract address: 0xece701c76bd00d1c3f96410a0c69ea8dfcf5f34e

A big thank you to the community for the level of patience and support you have shown us over the past couple of days, we are extremely happy to be back online. We can now look forward to getting back to the business of improving the platform and moving forward with our big ticket items, as discussed previously in our 3-6 month development road-map. Let’s roll!

Development update

Work completes today on updates to our smart contract and we begin internal testing of these changes; easier proof verification, improved fall-backs in the case of an oracle or data-source failure. This process should take us into Sunday. This being the case we are aiming for a live deployment early in the week.

Prior to the next live launch, funds from the discontinued game will be moved back into the primary bankroll multi-sig wallet before being transferred into the updated contract for go-live. The bankroll will pick up where it left off. e will update the community accordingly via our communication channels as progress is made.

In other news; we have opened dialogue with a UX/UI consultant and trusted designer to assist us in these departments into and during the next phases of the project. New designs will include mobile versions, in preparation for deployment to

Research into the new Ledger hardware based RNG generator with on-chain proof verification supplied by Oraclize has also begun, and we are excited to begin testing this out on test-net in the coming days and weeks before potentially migrating over to this new system for our RNG (TBC).

Thank you once again for all of your support and patience as we work on delivering this next round of improvements to our game. Let’s roll!

DDOS attack has been mitigated with server migration, improvements and upgrades.

Our site is back online. After a 24+ hour period of our server being under heavy DDOS attack we have migrated servers, upgraded, and implemented various server improvements to protect ourselves against future DDOS attacks. Whilst the particular DDOS attack we were under still has not stopped, we were able to solve the issue. Just another day in crypto really.

We can now get back to the business of updating, testing and re-deploying our smart-contract with improved fall-backs for any and all cases of oracle and/or data-source failures.

We do sincerely apologize for the recent downtime, and we really look forward to the game going live again ASAP. As of this very moment, we don’t want to give exact timings, but rest assured the game will be deployed onto main-net and live again as a matter of priority, always with safety in mind. Thank you for your patience.

Etheroll ÐICE tokens unlocked May 15 on EtherDelta Exchange. Learn More Here.

Hello World!

Following on from the success of our crowdfund (which raised 18,945 ether for the house bankroll) and the recent soft-launch of our Ethereum dice game, we are very pleased to announce that our ÐICE tokens become available for trading on EtherDelta exchange May 15th from 0900 UTC.

What is Etheroll? 
Our Ethereum dice game is provably-fair, has a low 1% house edge and no sign-ups or deposits. Each dice roll is provably random and crypto-graphically secure thanks to the nature of the Ethereum blockchain. Players can set their own odds using our unique web-based UI. *A world first for Ethereum!*

In the few weeks since our soft-launch, we have seen players wager up to 108 ether on one roll of the dice. Check out some of the other large wagers here (current live contract) and here (discontinued contract).

We are currently in the process of ramping up into full production. We recently raised our bankroll by 1000 ether, ~1/18th of our total bankroll. Bankroll increases will follow in a gradual order. You can read more on our development focuses in our 3-6 month development road-map here.

What is ÐICE?
We are inviting you to bet on the house. Our ÐICE token is an ERC-20 standards-compliant token, and a default token within MyEtherWallet and Parity.
ÐICE grants its holders special rights and privileges within the Etheroll platform; including the right to profit your proportional share of the house bankroll generates via our dice game with its built-in 1% house edge. For example, if you own 10% of all tokens, you have rights to 10% of the profit the bankroll generates, every 12 weeks.

Each ÐICE token grants its owner the following rights and has the following benefits:

  • Direct earnings – Proportional to the number of tokens they hold. Our valued token holders as a collective receive 100% of the profits their proportional share of the house generates every 12 weeks. House profits are generated via the 1% house-edge. Tokens holders are exposed to each roll of the dice with the advantage of the 1% house-edge always being in their favor.
  • A fixed total supply of 7,001,622.64 ÐICE, there will never be another mintage.

ÐICE Properties

  • Name: DICE
  • Decimals: 16
  • Address: 0x2e071D2966Aa7D8dECB1005885bA1977D6038A65

3-6 Month Development Roadmap. Week 2 Soft-Launch Review.

What an amazing couple of weeks. In the 16 days since we (silently) soft-launched our game to a very limited audience, our game has successfully processed almost 7,000 games with a total of >4000 ether wagered. We have already seen players wager up to 75.98 Ether on one roll of the dice. Wow! Check out some of the other large wagers here (current live contract) and here (discontinued contract).

The purpose of the soft-launch was to normalize our smart-contract and website and ensure the various smart-contract design patterns are working perfectly. Good news Great news, they are.

Following our recent and successful soft-launch, the past couple of weeks impressive performance of our game now has us looking towards the future of the platform and what we can do to improve the overall experience for our players and valued DICE holders. The following outlines our development plans and focuses over the next 3-6 months. These are our big-ticket items, and is no way an exhaustive list of items on our to-do list.

The purpose of the following points are to optimize our platform to the point that we can confidently market the platform to e.g. traditional Bitcoin audiences, and beyond. Admittedly, we aren’t perfect (yet), and we still have a lot of work to do, there may even be growing pains, but we are aware of the pain points and we fully intend to iron out the creases over the coming months in order to develop our product until it is the absolute flagship of dice games on top of the Ethereum protocol. Some of the items on our priority list over the coming 3-6 months are;

  1. Reduced Bet Processing Times
    We have a few tricks up our development sleeve (which we can’t reveal just yet) that we are researching and intend to work on with our development partners in order to significantly speed up the processing times of our game results over the next 2-3 months. These development improvements should also provide an array of benefits which will occur as a side-effect, including; improved game stability, transparency and reduction in gas (transaction) costs. More details to come over the next 2-3 months as we continue to develop and test these upgrades.
  2. Reduced Transaction Costs
    The recent rise in the price of ETH, coupled with the fact that miners have not reduced transaction costs has meant that transaction fees across the Ethereum network have risen due to a rising cost of gas. The average miner is still charging 20 gwei/gas, this should come down to 10 gwei/gas in the near future. Some have already reduced their fees, but not the majority. In any case, we aim to reduce gas costs for our platform by working together with our development partners in order to provide the lowest possible gas prices to our customers, we will achieve this by further optimizing our contracts and improving upon the usage of our oracle. We can’t disclose all the details surrounding our proposed changes just yet (top secret), but rest assured this item is high on our priority list. More details to come over the next 2-3 months.
  3. Deployment of the DICE Rewards Contract
    In order for our valued DICE token holders to claim their rewards, our ‘Rewards’ contract will be subject to internal testing and 3rd party security audits before being deployed to main-net in anticipation of our first rewards distribution week which opens August 7th, 2017. A new section added to our website will display a countdown showing exactly when (and how) you can claim your DICE rewards. This section will be deployed a considerable time before August 7th. You can learn more about the benefits of holding the DICE token by visiting today.
  4. Improved Overall Look and Feel
    We will be experimenting with new designs internally through the hiring of a designer and we look to implement a new and improved site design post August 7th after the first DICE rewards period.
  5. Mobile Version Deployment
    We understand the importance of being able to play our game on mobile. This is a potentially huge market for Etheroll. We look to be added to and look to have our game available on various mobile Ethereum platforms about the same time we deploy our new design.
  6. Full Metamask Support
    The Metamask team are working on updates to their core product in order to fix an issue which meant that our players were not being notified of results on the front-end even though in the back-end our smart-contract processed everything perfectly. We have just been notified that they have resolved this issue and we will make an announcement once their update has been deployed by the Metamask team. We can’t wait for our players to be able to use Etheroll with Metamask and we are really excited to offer this improvement to our players (we are big fans of Metamask).
  7. DICE Listings
    We are really excited to have EtherDelta list our DICE token starting May 15th. EtherDelta are a decentralized exchange, that leverages smart-contracts for trading. No need to worry about your tokens or even the exchange itself disappearing. We love EtherDelta for their smart-contract based exchange, but we need your support now in asking your other favorite exchanges to add our DICE token. For example, do you want to see DICE on BITTREX? Now is the time to tell BITTREX (Twitter) why you want DICE listed. How about exchange? Contact your favorite exchange and let them know why you want to see them list DICE today!
  8. Bankroll Increases
    Thanks to the success of our crowdfund in February, our bankroll has a total of 18,945 Ether. Our soft-launch game has been loaded with only 200 Ether so far. Over the coming days/weeks/months we will be gradually increasing the bankroll, which will allow our players to wager and win absolutely massive amounts of Ether.
  9. Marketing & Advertising
    Digital advertising in the form of banner and email campaigns, social media and a presence in various crypto-currency forums coupled with press-releases will allow us to expand upon our current early-adopter Ethereum audience. However, until we optimize our game (points above), we will not aggressively approach audiences outside of Ethereum. When we target, for example, the Bitcoin audience, we believe a game that is playable on mobile, that is fast, cheap and reliable will be the best way to win over new audiences in our target markets. Our primary target audience for the next 3-6 months will be early adopters of Ethereum. Beyond the next 6 months we intend to reach out to audiences of other crypto-currencies, (e.g. Bitcoin) with forum posts and banner campaigns on the various and relevant publishing platforms.
  10. High Roller + Low Roller Game
    We are starting to discuss the possibility of deploying an additional ‘low roller’ game which will allow players to wager tiny amounts of Ether. The way we will achieve this is to reduce the maximum profit for this particular game to be below 5 Ether for any bet placed. We are still researching this option, and we don’t want to give away or promise too much yet, but it could be something you see coming from us in the next <6 months.

Whilst this may not be a complete and/or detailed description of our development focus for the next 3-6 months, we do believe that it does provide some insight into what we currently have planned. Most of the items we have in the development pipeline, we can’t actually publicly discuss in detail yet, as they are still top secret (and for good reason)!

Support Requests

We are pleased with the level of support requests we are receiving, with only a tiny fraction of players requiring any sort of support from us, and most are related to the Metamask issue (we currently only fully support Mist browser). We are eager to reduce this number further once the Metamask team resolve their issue and deploy their latest version.

Recent Updates

Today we have deployed a new section to our website which displays real-time data about the game, including total Ether wagered, total Ether won, and the number of games played (you will only see this section if you are connected to an Ethereum node). We have also added a new section to our site outlining the benefits of owning DICE tokens. We will be increasing the bankroll this week, and have migrated our entire site to be served via https (SSL) as an additional layer of security and confidence for our players.
