- 1. Dropsession
-
- We are proud to present to you : Dropsession, a new and exciting puzzle game.
- Those of you who are not afraid of a little bit of puzzling will be pleased
- with it, we think... The idea behind the Dropsession puzzles is simple yet
- very powerful. The difficulty of the puzzles ranges from easy to very hard.
- Even puzzles looking extremely simple can turn out to be far from easy.
- Solving the puzzles will often prove to be a real challenge. You will need
- to plan ahead, you will have to build temporary constructions which will be
- removed later on, you will have to decide where to start etc.
-
- Anyway, so we are very exited about the puzzles and the Dropsession program.
- Why don't you find out if you are? Just play the game! But be sure to read the
- documentation first.
-
-
- 2. The puzzle
-
- 2.1. A short description
-
- The goal of each puzzle is to build a given figure on a two dimensional board.
- You will have a restricted set of pieces for each puzzle.
-
- Pieces which are on the board are subject to a forcefield. This forcefield can
- be orientated in one of two directions (these two directions are 90 degrees
- apart). The forcefield will drop pieces as far as possible (until they are
- obstructed by a border of the board or by other pieces). However, the
- forcefield will never rotate the pieces. So the orientation of each piece
- stays fixed. You are able to switch the direction of the forcefield. The
- forcefield is the only way to move the pieces on the board.
-
- The board has two entrances which you use to insert pieces on the board. Which
- entrance you can use is determined by the active direction of the forcefield.
- You pick a piece that is still available and position it as you wish in front
- of the entrance. You then insert the piece. Once the piece is on the board,
- the forcefield will cause it to drop as far as possible in the direction of
- the forcefield.
-
- Often you are given more pieces than are necessary to form the figure. These
- extra pieces can be used during the construction of the figure. At the end of
- the puzzle they have to be off the board again. The board has two exits which
- can be used to remove pieces from the board. If you open the exits the
- forcefield may cause pieces to leave the board through one of the exits. The
- exits then close. You can use the pieces which left the board again later on.
-
-
- 2.2. The actions in a nutshell
-
- To summarize the above. The three actions you have at your disposal to solve
- the puzzle are:
- - Switch the forcefield to the other direction.
- - Insert a piece on the board through the active entrance.
- - Remove pieces from the board by opening the exits.
- Sounds simple, huh? How could these puzzles ever be hard? Well, they can.
- They really can. Play a couple of the puzzles if you don't believe us.
-
-
- 2.3. Exceptional situations
-
- The above description is not yet complete. There are still two exceptional
- situations:
- (1) If you drop a piece and it can not completely get on the board it will be
- rejected.
- (2) If you open an exit and a piece gets halfway but cannot completely leave
- the board you are not allowed to play any further. You will have to start
- again from the start or go back using the undo-function.
-
- Furthermore, for some puzzles you are not allowed to 'build to the entrance'.
- This means that when you rotate the forcefield, the area of the board under
- the current entrance has to be entirely empty if you want to insert a new
- piece. Otherwise the entrance will be closed making it impossible for you to
- insert a piece. In this way it is as if you have to solve the puzzle on a very
- large board. It is done to make the solutions for some puzzles a bit nicer
- (and harder!).
-
- You can find out if you are allowed to 'build to the entrance' by looking at
- the information for the puzzle.
-
-
- 3. How to use the Dropsession program?
-
- 3.1. How to start puzzling?
-
- Simply choose 'Play puzzle' in the main menu. You will first see some
- information on the puzzle. When you have seen this information, you press a
- key and you can try to solve the puzzle.
-
-
- 3.2. Solving the puzzles
-
- The actions you can use to solve the puzzle, are given elsewhere in this
- document, see the chapter 'The Puzzle'. You can find out which keys you have
- to use to perform these actions by pressing 'F1'.
-
-
- 3.3. What if I solved a puzzle?
-
- When you have solved a puzzle, you automatically go to the next puzzle. Always
- write down the code for this new puzzle immediately!
-
-
- 3.4. What about the puzzle codes?
-
- Each puzzle has its own unique set of codes. These codes enable you to go back
- to any puzzle where you have been before.
-
-
- 3.5. Start off where you left
-
- You can go to any puzzle where you have been before by using the 'Goto puzzle'
- command. Simply enter the number of the puzzle and its code. Then choose 'Play
- puzzle'.
-
-
- 3.6. What if I am stuck?
-
- It is possible that you are stuck at a certain puzzle. That you really have no
- idea how to solve it. Or that you're so extremely close to solving it, but
- just not close enough.... You can then skip that puzzle and go on with the
- next puzzle. Choose 'Skip puzzle' in the main menu. You are only allowed to
- skip up to a certain maximum number of puzzles (we think that number is
- two....).
-
-
- 3.7. Help, the puzzles code are starting to look weird! Is it a bug?
-
- No, once you skipped a puzzle the puzzle codes will be a random-looking
- combination of characters and digits. This new code indicates that you skipped
- one or more puzzles. So if you restart Dropsession and use this code to go
- back to a puzzle where you have been before, the program will know how many
- puzzles you skipped up till then.
-
-
- 3.8. Solving puzzles you once skipped
-
- Simply go to a puzzle you skipped once by using the 'Goto puzzle' command.
- Then try to solve this puzzle again.
-
-
- 3.9. What to do when I solved a skipped puzzle?
-
- When you solved a puzzle which you had once skipped, you will see that the
- puzzle code for the puzzle immediately following the skipped puzzle has
- changed. Write down this new code. The code has changed to reflect the new
- situation (for the number of puzzles you skipped up till then has decreased).
- However, if you have any codes for puzzles with a higher number, these should
- be changed at well. And uh,..... hmm.... that is where things get a bit
- complicated.... Sorry. Really. But don't fear, you do not have to solve all
- these puzzles for a second time. You use the 'Validate puzzle' command to
- avoid this. You will have to give the code for the next puzzle, and then you
- will receive the new code for that puzzle (write it down!). Work your way
- through all puzzles by validating them..... Ah well, that's not too hard
- after all, is it?
-
-
- 4. The freeware version
-
- 4.1. Features
-
- - 17 different puzzles.
- - A built in demo-mode.
- - Undo & redo function (only up to 2 levels)
- - A code system so you can restart whereever you left the previous time. You
- are even allowed to skip a puzzle at which you are stuck. But only up to
- a certain extent.
-
-
- 4.2. Requirements
-
- The freeware version is designed to run on almost any computer which runs DOS.
- If your screen supports a 80x25 text-mode with at least sixteen colours there
- shouldn't be any problems to run the program. Or your computer should really,
- really be ancient...
-
-
- 5. The registration version
-
- 5.1. Features
-
- - More puzzles (at least 25 new puzzles, but this number will grow!)
- - Undo & redo up to 20 levels
- - Save & load your (partial) solutions. You will be able to restart from
- anywhere in these solutions.
- - A nicer appearance. It is still text-mode though, but considerably neater.
- And if you are longing for a graphical version, read on!
-
-
- 5.2. Requirements
-
- If the freeware versions runs on your computer, the above registration version
- should also work.
-
-
- 5.3. Future plans
-
- Some things we have in mind to do in the near future:
- - More puzzles!!!!
- - A 256 color graphical version. Raytracing will be used to create a realistic
- board and pieces. You would puzzle with (for instance) marble pieces and a
- wooden board! This graphical version is not yet available. However, as
- soon as 50 users have registered, it is guaranteed to be released!
- - Small improvements like defining your own keys.
-
-
- 5.4. Why register?
-
- - You will get more puzzles!
- - You will receive the registration version of the program (more
- functionality, better looking, etc. See the features of the registration
- version)
- - It costs you only 10 US dollar to register for life! You will then be able
- to get all future versions and all new puzzles for free. Be quick, when
- the registration package gets more comprehensive the registration fee will
- increase. So you will save money if you register now!
- - You will support the environment by registering! Part of the registration
- fee (10%) will go to the WWF (read on for more information).
-
-
- 5.5. How to register?
-
- Print out the file REGISTER.TXT and fill in the form. You will find more
- information in the file itself.
-
-
- 6. Contact us
-
- You can always contact us. You can find all the addresses you need at the top
- of this document.
-
- Contact us...
- - ... when you have questions or want to get more information.
- - ... when you want to give us your feedback. We would be very happy to
- receive any feedback on this program.
- - ... when you want to register. Check out the file REGISTER.TXT for more
- information.
- - ... when you have found a shorter or better solution for a certain puzzle.
- It can be that your solution takes less rotations or that you do not
- use all the pieces that are available (for instance, your solution
- leaves the small unit square for the Devilish Diamond untouched. Which
- would be quite an achievement by the way). What's in it for you?
- Eternal fame: your name will be mentioned by the solution of the
- puzzle.
- - ... when you have designed some neat puzzles and you don't mind that we use
- them. Eternal fame will be yours again: you will get your name
- mentioned by each of your puzzles which we use. Furthermore, when you
- give us several puzzles of a good quality, you can also expect a small
- reward in return. Don't hesitate to ask for more information when
- you're interested.
- - ... when you discovered a bug in Dropsession. We hope that this will never
- be the case. But it is possible since the sourcecode of Dropsession
- has gotten pretty big (over 200k C++ code).
- - ... when you think there is another reason to contact us.
-
-
- 7. Support the environment
-
- Eriban Software is pretty concerned at the way the world and her natural
- environment is going. Therefore, we will give 10% of all revenues to the WNF,
- the dutch organisation of the WWF ("World Wide Fund for Nature" also known as
- the "World Wildelife Fund"). We feel that that's the least we can do.
-
- WWF's Mission:
- To reverse the destruction of the Earth's natural environment and build a
- future in which humans live in harmony with nature.

-
- 8. Frequently asked questions
-
- At the moment of writing this documentation, the program is not yet released.
- So there haven't been any questions so far. But if you have any questions, ask
- us. You can visit our homepage, email us or write us. All the addresses you
- need are at the top of this document.
-
-
- 1.1 Will there be a Windows version available in the near future?
- - Nah, think not. Eriban Software feels that they should not in any way
- help Bill and his friends in a monopolizing marketing position.
-
- 1.2 But does Eriban Software realize that this will mean that they throw
- away a good chance to make some extra money?
- - Yes, but making money is not everyones main goal in life. Some people have higher morals.
-
-
- 2.1 Is this product environmental friendly?
- - Yes.
-
- 2.2 Why?
- - First of all, no first multi-megaherz mega-memory hardware is required
- to run this piece of software. So you can refrain from buying the newest
- (even faster and better) computer model around. You can still use your
- old computer. You don't have to throw it away! This will effectively
- reduce the world's wastebelt by one (still perfectly functioning)
- machine.
-
- 2.3 Oh, oops. But what if I already made the mistake of buying the latest
- computer model?
- - Those who did, can still save some precious energy by switching their
- power consuming piece of hardware from the highspeed mode to the rarely
- used but still useful low-speed mode. Try it!
-
- 2.4 That's indeed all very impressive. Is there more?
- - It's nothing compared to the above ;).... but it deserves to be
- mentioned anyway: 10% (or even more when things start to work out) of
- all received payments will be donated to the WWF. And that's a promise!
-
-
- 9. Major thanx
-
- An incredible bunch of thanx go out to Savatage, Blind Guardian and Pique
- Poque Poetry, without their inpiring music the creation of this program and
- the underlying ideas would be inconceivable. And that's no lie!
-
- Furthermore, thanx go also out to: Paul and Calslaan 7-2 for providing
- feedback and the NKC for publishing an article on Dropsession in their CFF
- magazine (puzzle lovers, we can highly recommend this magazine to you, ask us
- for more information if you're interested).
