Hi there! The Impossible Bottle can be played in one of three different ways, according to taste: Online web, offline web, or Z-machine. If you are unsure what to pick, try the online version: Open the file "index.html" in a web browser, and select "Play online". If you are using a screen reader, the Z-machine version may be more accessible. Open "the-impossible-bottle.zblorb" in a Z-machine interpreter, such as Frotz or Gargoyle. The web version can be played by typing commands, clicking on hyperlinks, or a combination of both. The Z-machine version only supports typed commands. Have fun! Linus
