This is a web-based Hangman Game. I feel that the video above demonstrates how it works better than a written description can, but here's the best description I can come up with for now:
This is a web-based Hangman Game. It begins with a blank canvas, a partially-visible word (the rest of the letters being blanks to be filled in by the player) with a complete alphabet on-screen keyboard below it, and a single hint in the form of a definition, synonym or antonym of the word. The "Hint" button below the visible hint can be used to generate up to four more hints (one at a time), after which, if the Hint button is clicked, some of the blanks will be filled in at the cost of a body part of the Hanged Man for each filled blank. The man will be drawn on the canvas so the player can keep track of their progress. The player fills in blanks by dragging letters from the on-screen keyboard and dropping them on the corresponding blank. If the word is successfully completely filled in before the man is hanged, a button appears at the bottom of the canvas which the player can use to move on to the next word. This process repeats until the man is hanged, at which point the game ends. This is an untimed game.
