The Colossal Cave

Solve:
———
1. Enter building. Get keys and lamp. The lamp appears
  here should you have to be reincarnated.
2. Unlock gate (with key). Get cage.
3. Try the magic word, XYZZY. Try it again. Get rod.
4. Drop rod. Get bird. Get rod.
5. Wave rod. Drop rod. Go get diamonds and gold.
6. Release bird. Drop cage. Grab coins and silver.
  Note: Dwarves are lousy shots, but sometimes,
  unfortunately, they can get lucky. Carry the ax, as you
  may encounter up to five of these critters.
7. Try the magic word PLUGH also. Drop silver, gold nugget,
  diamonds, jewelry, and coins. If you haven’t already, you
  will soon encounter a thieving pirate. Not to worry, he’s
  got to rob you at least once if you’re to win all the marbles.
8. Carrying food, ax, bottle of water, key (all for later)
  and lantern, visit the software den (Microsoft Version only).
  Don’t mess with anything—Software types are a weird lot.
  Get magic word LWPI. Works only from here.
9. Water plant twice. Get water for the second pass at the
  waterfall.
10. Attack dragon. Yes. Get rug.
11. Get oil (in now empty bottle). Climb the plant.
12. Oil door. Open door. Drop bottle. While here and while carrying
  golden eggs, enter FEE, FIE, FOE, FOO, one word at a time. Check
  your inventory. Go back to where you first found the eggs.
13. Throw eggs (to troll). Cross bridge before the FEE, FIE, whatever.
14. Feed bear. Unlock chain (with key). Get golden chain. Drop key.
  Get bear. Don’t forget the rare spices. At volcano view, read and
  remember the words of fire.
15. Release bear. Don’t try crossing the bridge with him on the chain.
16. Open oyster (with trident). Pearl will roll down into the
  cul-de-sac.
17. Insert coin to get a replacement battery for your lamp,
  if necessary. Coins are a treasure, however, and you won’t ge
  them back, so try beating the game with the original batteries
  only.
18. Never drop vase unless you have already dropped the pillow.
19. Drop everything in order to enter. Get emerald.
20. Say PLOVER. Get pyramid. PLOVER, PLUGH and pi-tooie!
21. You must traverse the maze to get Pirate’s Treasure
  Chest, which doesn’t appear until he’s robbed you.
  Return via the Pit and XYZZY. Drop all treasures in  
  the House.
22. Drop magazine in Witt’s End for a point. Get out by
  entering all different directions except north. It may
  take a while. Slog around in various and distant locations
  until a voice announces that the cave is now closed.
  At this point you are teleported to the two-room Master’s
Game.
23. Get black rod (with the rusty marks, not the star).
  Drop rod in the northeast room. Retreat to the southwest
  room. Type blast. Alternate endings are possible, but
  will not yield sufficient points to earn you the rank
  of adventure grandmaster.
