[![30 second exposure](https://i.postimg.cc/85RbfyGp/Logo1-2.png)](https://poker.graphenelab.io) Hello! The New Year celebrations are already over, but despite that we have a small (or rather not so small) present for you. Since the end of December we (didn’t sleep at nights) we were doing an internal testing for an innovative EOSIO based product and now we are ready to present it to you for the public testing. Yes, it is a poker, or rather the first truly decentralized multiplayer PVP Texas Hold’em platform based on EOSIO **(which is currently active on EOS Jungle 2.0 testnet)**. We’ve selected EOS Jungle 2.0 testnet, as it is closest to the EOS Mainnet, as well as it allows anyone to create a **free** account, get test EOS tokens for the game mechanics testing ### Before you start testing, we recommend you to get acquainted with the following information. 1. The game uses decentralized deck shuffling using the players clients. DO NOT force close the client if you are at a table, as you will not send the keys to decode the cards, and other players won’t be able to finish the game. To exit the game correctly please use the EXIT button (that will cleanly shut down the application). In the future we will be adding penalties for closing the application incorrectly. 2. The game happens on chain, and the process of the game is controlled by a smart contract. Players interact with the smart contract via the game client, by pushing transactions into the blockchain. If the player does not have enough resources to proceed with an operation (i.e. sending keys) other players will be unable to finish the game correctly. In the future there will also be penalties for it. 3. To minimize the load on the EOS network, and optimize resource utilization (as Dan suggested in [Developing Efficient Contracts](https://medium.com/@bytemaster/developing-efficient-contracts-8a8e62011c6d)) the smart contract uses internal deposit accounts for the clients. The funds are instantly withdrawn to players accounts on request (currently that is done by pressing the EXIT button). 4. Please make sure that you’re getting the application from the official repository. We do are not liable for any external binaries. Official link to the current release is: https://github.com/GrapheneLab/PokerChained/releases
At this stage of the public testing, the following functionality requires thorough testing: overall poker logic (raise/reraise/call/fold/all in/creation of the main and side pots/choice of winner(s)/autorebuy), shuffling, encoding/decoding the cards, interaction between clients and smart contract, deposit/withdraw of funds from the smart contract. **For that reason there are some points that you need to keep in mind during testing**: * **Current client has the minimal functionality, as well as some mandatory limitations, and is a so called “MVP” for testing of the main game logic** * **The game happens on chain, so please make sure that your resources are enough to continue playing, and do not force close the client so that the game is still playable for other game participants** * **It is currently impossible go leave the table to the game lobby, so to change tables, chose another node, change the bet amount you need to restart the application. It is imperative that you do so via an EXIT button, and relaunch it manually** _More details of the current client implementation are described below._ ##### Quirks (limitations) of the client due to the current testing phase: 1. Current build lacks **Scatter** (or other key manager) integration. Currently to play you need to enter your private key into the client 2. Player turn time is increased to **55 seconds** 3. Card shuffling and encryption times are increased (also depends on the amount of players at the table) 4. Localization is almost nonexistant, some settings in the menu are inactive, some animations are unavailable. 5. Fund withdrawal from the internal account in the contract to your account is currently possible through the button to exit the table and close the application (`EXIT`). 6. Your current internal game balance is not displayed anywhere (if you like you can still see it in the contract table: https://jungle.bloks.io/account/pokerchained **Contract tab > contract tables > quanitity_**) 7. The client does not show the current available resources of the account. You can manually keep an eye on them at https://jungle.bloks.io 8. The original **buyin** stake is limited and set at **10 Big Blinds** 9. There is no navigation in the client to go back to previous menu (e.g. to pick another node) you’ll have to close the client and restart it. 10. After the hand finishes, players have **20 seconds** to confirm that they are ready to continue playing at this table. If they do not press the button in that time, they will be automatically returned to the lobby. 11. The setting to have **9** player table is disabled (only a table for **5** players max is currently available). 12. The ability to choose small blinds in the game is currently limited to **0.1, 0.5, 1, 10 and 100 EOS**. 13. Autorebuy is set to trigger if the player stake goes below one **Big Blind** 14. Poker room fee is disabled (rakes are set to 0) 15. Referral system, cashback, etc are currently disabled 16. Winner combinations are not highlighted at the end of a hand (temporarily the hole cards of the winner and card on the table are highlighted, with text notification with the name of the winning combination). > At further testing iterations an improved client version will be released, with lower times for different actions, as well as testing for mobile clients **(iOS/Android)** and **Web version**, which is being developed separately *** P.S. P.S. Game variant is classic unlimited Texas Hold’em, you can check the rules at the following [link:](https://www.pokerstarsschool.com/article/Poker-Rules) *** Please report the bugs on [Github](https://github.com/GrapheneLab/PokerChained/issues), we are also looking for feedback, which you can leave at the form below (https://goo.gl/forms/SBtKRe6l5VgWbBpe2).

Each hand starts with shuffling and encrypting the deck by every player. We will release another article with the description of the process at a later date, stay tuned! ![](https://i.postimg.cc/6Q3s0vqx/2019-01-17-12-40-00.png) After the cards are dealt the hand of classic Texas Hold’em begins. We recommend you get acquainted with its [rules](https://www.pokerstarsschool.com/article/Poker-Rules) beforehand During the game you can see the name of your current combination with the help of the button located at the bottom left (combinations are shown in order of precedence from top to bottom) ![](https://i.postimg.cc/W1NxNkMq/2019-01-16-23-08-00.png) Also available is a button to increase the size of the current bet - **Raise** (also temporarily through it the opportunity to make the first bet (BET) and the ability to go **all-in** ![](https://i.postimg.cc/Bb2R65YH/2019-01-16-23-10-55.png) A **Call** button to ante up to the current bet amount ![](https://i.postimg.cc/XvhPk1t9/2019-01-16-23-07-28.png) **Check** to skip your betting round, or **Fold** your cards ![](https://i.postimg.cc/vmDj9w2Q/2019-01-16-23-07-52.png) Please note that each player has **55 seconds** (displayed as a timer at the lower part of the window) for their action, and is the player doesn’t do anything during that time, the cards will automatically **fold**. At the end of the hand, a winner(s) are determined, and main/side pot(s) are awarded. The winning combination(s) are displayed in green above player’s icon ![](https://i.postimg.cc/2Y0SqxLB/2019-01-17-12-44-38.png) > **Please take note of the timer between hands with two buttons (Continue/Exit). You have to confirm that you wish to keep playing at this table before that time elapses. If you do nothing when the timer runs out you will be removed from the table.
