Game state management - a game of hangman

This is a game of hangman. A user can mint a new game using safeMint just like any NFT. Other players can play the NFT using guessLetter by submitting a target tokenID and their letter guess.

All game state and updates are shipped off to a table on Tableland.

The NFT is built on IFPS and reads that state to render the live game.

You could also easily build a dapp for viewing leaderboards, open games, etc.

Gameplay

A user calls `safeMint(addr, "secret"). That user (addr) now owns an NFT for the game, awaiting people to guess "secret".

A player can now call `guessLetter(tokenId, "x"). Because "x" is not in "secret" one fail will be recorded. If 6 fails are recorded, the game ends and the NFT transfers back to the smart contract. If all the letters of the word of guessed before the game is over, the person submitting the final letter will get the winning NFT.

The state at each level is pushed to Tableland for rendering, query, search, etc.

Example deployment (how to play)

You can view the full state of the example deployments below running in the above table.

You can query that state here,
