Plutus Playground Smart Contract
-- A game with two players. Player 1 thinks of a secret word
-- and uses its hash, and the game validator script, to lock
-- some funds (the prize) in a pay-to-script transaction output.
-- Player 2 guesses the word by attempting to spend the transaction
-- output. If the guess is correct, the validator script releases the funds.
-- If it isn't, the funds stay locked.
