Краткое описание конкурса

Create software to reduce the state of a Poker game by events

The software to create will reduce/compute the state of a Texas Hold Em Game. Reducers are pure functions that specify how the application's state changes in response to events. Events are simply objects that have a required type and an optional payload.


REQUIREMENTS:
-Javascript/NodeJS (Typescript strongly preferred)


The architecture of the software is event based; in other words, the inputs will be events and the software should create snapshots of state (to a file) after each event is processed.

Feel free to redesign the input events and/or state to improve the system, the only requirement is that your software will have to process the events.

It is sufficient for your program to process the input events from a JSON file, and to output state snapshots to another file.


Here might be the initial state of the game:


export const INIT_DEALER: IDealerState = {
'communityCards': [],
'options': {
'smallBlind': 5,
'bigBlind': 10,
'gameType': [login to view URL],
},
'seed': {
'buttonPosition': 0,
'players': null,
'playersWhoStartedTheGame': [],
'deck': []
},
'players': null,
'pot': 0,
'temporaryPot': 0,
'playersInPlay': [],
'bettingQueue': [],
'timeout': null,
'status': [login to view URL],
'winner': null,
'wagerToCall': 0,
'timeAddRequested': false,
'rabbitRequested': false,
'roundComplete': false,
'gameStarted': false,
'gameOver': false
};


These are the different event types that your software must respond to:

export enum DealerEvents {
LOAD_GAME = 'LOAD_GAME',
CHECK= 'CHECK',
CALL = 'CALL',
FOLD = 'FOLD',
BET = 'BET',
RAISE = 'RAISE',
ALL_IN = 'ALL_IN',
HUNT_RABBIT = 'HUNT_RABBIT',
ADD_TIME= 'ADD_TIME',
TIMEOUT= 'TIMEOUT',
ADVANCE_ROUND= 'ADVANCE_ROUND'
}

Here might be an example input JSON file with example events (remember you can redesign the events/state as you need):

type: 'REGISTERED', payload: {'options': {'gameType': 'NoLimitHoldEm',
'smallBlind': 5,
'bigBlind': 10}
, 'seed':{
'players': {
'123': initPlayer('123', 1000), // A player object with id ‘123’ and chip stack 1000
'abc': initPlayer('abc', 1000),
},
'playerIdsWhoStartedTheGame': ['abc', '123'],
'deck': ['As', 'Kh', 'Ah', 'Kd', 'Ad', '2d', '3d', '7c', '8c', ...], /*CardIds are strings that are made of 2 characters, the RANK (A = ace, K= king, J= king, T=10, 9 = 9…. , followed by a lowercase suit*/
'buttonPosition': 0

}}; // Load game with options and seeds
{ type: [login to view URL], payload: {playerId: '123'} }
{ type: [login to view URL], payload: {playerId: 'abc'} }
{ type: DealerEvents.ADVANCE_ROUND, payload: {} }// To flop
{ type: [login to view URL], payload: {playerId: '123'} }
{ type: [login to view URL], payload: {playerId: 'abc'} }
{ type: DealerEvents.ADVANCE_ROUND, payload: {} }// To turn
{ type: [login to view URL], payload: {playerId: '123'} }
{ type: [login to view URL], payload: {playerId: 'abc'} }
{ type: DealerEvents.ADVANCE_ROUND, payload: {} }// To river
{ type: [login to view URL], payload: {playerId: '123'} }
{ type: [login to view URL], payload: {playerId: 'abc'} }
{ type: DealerEvents.ADVANCE_ROUND, payload: {} } // To showdown




Remember, after each event, record the snapshot of the current state to a json file. (So if there are 10 events, you should have 10 snapshots)

    Hello,
    I just submitted an entry for your other contest. I wanted to say that I'd like to submit an entry for this one as well but unfortunately will not have time this weekend to work on a solution. If the contest closes prior to my submission and you would like for me to build/send you a solution please message me and let me know. I'd be happy to work the project.
    Thanks,
    Ryan P.

    Hello,

    I just found your contest, but there are some details that are not clear.
    I understand that you want an event sourced software that should keep the state of a Texas Holdem Game, but should it view the entire game state or just what is seen by the dealer?

    In other words, should the program keep a list(["Kd", "Ad"]) of all the players cards at all moments? Even while he has not shown the cards.

    Well if there is no UI then how do u want the result to be shown?

    Hi, could you give a basic example of the system should work? And can I use Golang instead of NodeJS? Reply ASAP

      I gave examples in the descriptions. Create a poker software that deduces the state from a series of events. The state object and the event object must be a JSON, but it can have any properties you see fit.
