Puzzler 🎲

A simple Ethereum based decentralized application demonstrating usage of ERC-721 tokens.

Description

• Answering questions would increment the level for the user.
• Each puzzle solved mints an ERC-721 token (PZLR), which is owned by the smart contract. Called 'Spiro' in the game.
• Each Spiro is representative of:
  • creator
  • level at which it was created
• Each user can own a single Spiro that represents the current level of the user in the game.
• User has an option to sell that spiro
  • would reset his/her level to 0
• Available spiros with level strictly greater than user's level are displayed in the left. These spiros can be bought to level up.
• Total number of questions is the number of questions available in the database - currently a .json file
  • can also be seen as the "max level reachable"
• Contract is currently deployed on Ropsten Testnet

Usage

• 0 PZLR or the 0th Spiro is the initial token - basically, nothing can be done with it. Think of it as a null/starting token
  • the 0th question generates 0th spiro
• Each user can own only a single spiro
• Answering a question
  • correctly
    • increments your level
    • generates a spiro with your address as the creator and your level
  • incorrectly
    • generates an alert on the page
• User can buy one of the spiros owned by the contract - to level up.
• User can sell his/her owned token - would change level and spiro to 0.
