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

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.
