Welcome to the Lottery Game, a simple web-based application where you can participate in a lottery draw, buy tickets, and try your luck to win prizes!

1. Getting Started:

   • Upon opening the game, you are greeted with a default player profile.
   • You have an initial balance of 10,000 coins.

2. Buying Tickets:

   • To participate in the draw, you can buy tickets by clicking the "Buy Tickets" button.
   • Each ticket costs 500 coins.
   • You can specify the number of tickets you want to buy by entering the desired quantity.
   • Alert: If you attempt to buy tickets without sufficient balance or if tickets have already been purchased for the ongoing draw, an alert will notify you.

3. Start Draw:

   • Once you have purchased your tickets, you can click the "Start Draw" button to initiate the lottery draw.
   • Alert: If you attempt to start the draw without buying enough tickets, an alert will prompt you to purchase more tickets.

4. Draw Results:

   • After starting the draw, the game will generate five random numbers as the winning draw.
   • Your tickets are compared with the drawn numbers, and the results are displayed.
   • The results include the number of hits for 5, 4, 3, and 2 correct numbers, as well as the total prize and operator profit.

5. Prizes and Operator Profit:

   • The prize for hitting 2, 3, 4, or 5 numbers is determined based on a predefined prize table.
   • If you do not win any amount, the total ticket price contributes to the operator's balance.
   • Operator profit is calculated as a percentage of the total prize.
   • The operator's profit percentage is set at 10%.

6. Balance Update:

   • Your account balance is updated based on the prizes you win.
   • If you do not win any amount, the total ticket price is added to the operator's balance.
   • The operator's balance is adjusted to reflect the operator's profit.

7. Resetting the Game:

   • You can reset the game at any time by clicking the "Reset Game" button.
   • This action restores the initial player and operator states.

8. Operator Dashboard

The Operator Dashboard is a web application designed for operators to manage and view details of players participating in the lottery game. The dashboard provides insights into player information, purchased tickets, and winning amounts.

• View a list of players along with their details.
• Access information on each player's balance, total winnings, and purchased tickets.
• Monitor the submitted tickets by players for each draw.
• Track the winning amounts for each player based on the draw results.

The game consists of two main components:

• Player Component:

  • Displays the player's name, balance, winning amount, and allows purchasing tickets.
  • Shows the player's tickets in a table format.

• Operator Component:

  • Displays the operator's balance.
  • Initiates the draw, shows drawn numbers, and presents round results.

• The game is built using React.js.
• State management is handled using React hooks (useState and useEffect).
• Data is fetched and saved to a fake API endpoint.
• Random numbers are generated for the draw.
• Prize calculation and balance updates are based on predefined rules.

Feel free to explore, enjoy the game, and good luck with your lottery draws!
