Installation

No particular installation is required.

Usage

1. Go to Remix which is an online IDE designed for Solidity.
   
2. Copy the source code from RockPaperScissors.sol, locate it under the browser folder.
   
3. Compile the code by clicking "Start to compile" button under "Compile" tab on the right pane.
   
4. Navigate to "Run" tab, choose JavaScript VM environment.
   
5. Press the deploy button in order to deploy the contract.
   
6. You will now see a contract under "Deployed Contracts" section.
   
7. Then choose any account from "Account" drop-down list. This account will be a player for the game.
   
8. After choosing a player, join the game by pressing the "join" button. Make sure you pay the stake of 1 ether. This can be done by typing '1' next to "Value" and choose "ether" in the drop-down menu.
   
9. Change account and join the game by repeating the processes 7 and 8 above.
   
10. Now press "makeChoice" button to make a choice. A valid choice will be one of "R", "P", "S".
    
11. Repeat again for another account we made.
    
12. Then disclose the game result. This can be done by pressing "disclose" button.
    
13. Once the outcome of the game is disclosed, you will gain/lose 1 ether unless you draw.
    
14. When the game is over, you can repeat the processes 7-13 to play the game again.
    

Todo

1. Implement a code for encrypting the user input for security.
   
2. Add timeout logic after a player making a choice.
