- 1. R U L E S O F M A T H A B L E
- =====================================
-
-
- 1.1. INTRODUCTION
- -----------------
- MATHABLE is a SCRABBLE-like game. It can be played with 2, 3, or 4
- players.
-
- The computer can take the place of one or more of these players.
- (To do this, choose for the player's name to begin with the letters
- COMP, e.g. COMPUTER, COMP-A, COMP1). Computer can play also against
- itself (Computer 'solo', e.g. by choosing names: COMP-1, COMP-2).
-
- Each player begins the game with a rack of 7 tiles, which, unlike
- SCRABBLE, have on them, not letters but numbers. The tiles are
- taken out of the 'bag' randomly and distributed to the players. The
- first player to play is also chosen randomly.
-
- 1.2. THE BOARD
- --------------
- Much like a SCRABBLE board, the MATHABLE board has special squares
- ([2x], [3x]) for double or triple values of the tile placed on them.
- It also has several squares ([+],[-],[x],[:]) which depict one of
- the 4 signs of addition, subtraction, multiplication and division.
- The function of these squares will be explained later. In the center
- of the board, the following 4 tiles are preset:
-
- [1][2]
- [3][4]
-
- 1.3. THE RULES
- --------------
- A tile is placed on a specific square on the board only if the
- number on it is the result of addition, subtraction, multiplication
- or division of the two numbers that are found above, below, left or
- right of this number.
-
- Example: The game begins with the tiles [1], [2], [3], [4] preset
- on the center of the board so that some results can be generated and
- the game can be put into action.
-
- Let's say you have a [7] on your rack. If you're the first player
- you can put this [7] in the square which is exactly right of the
- already existing [4] (because 3+4=7) or in the square which is exactly
- left of the already existing [3] (for the same reason). If you have a
- [2] you can put it in many squares:
-
- 1) above [1], because 3-1=2
- 2) below 3, for the same reason
- 3) above 2, because 4-2=2 (or 4:2=2)
- 4) below 4, for the same reasons
- 5) right of 2, because 2x1=2 (or 2:1=2)
- 6) left of 1, for the same reason
- ... you choose the one you want.
-
- In conclusion: You can perform addition, subtraction, multiplication
- or division between 2 numbers that are next to each other,
- horizontally or vertically, and place the result of this operation
- in the same column, or row, next to these 2 numbers.
-
- Say you put [7] here -----\
- |
- | [1][2]
- [7][3][4]
-
- And you have a [21] on your rack, you can go on playing, because
- you can put it left of the tile [7] (7x3=21).
-
- When you have nothing more to put on the board, you pass on to the
- next player, and you rack is filled with new tiles so that it always
- has 7 on it (unless there are no more tiles in the 'bag');
-
-
- 1.4. SCORING
- ------------
- Each player receives points for each tile he/she places on the board.
- Generally these points are the face value of the tile, except if this
- hits on a [2x] or [3x] square which doubles or triples its value.
- The points are also doubled or tripled in a situation like the
- following:
-
- put 3 here -------> [3][6]
- [3][1][2]
- [1][3][4]
-
- and you get 6 points because 3 is 6-3 (the horizontal subtraction)
- and 1x3 (vertical multiplication).
-
- If one player places his/her 7 tiles all in one turn he/she gets 50
- points extra bonus.
-
- 1.5. SPECIAL SQUARES
- --------------------
- The special squares have on them one of the 4 signs (+,-,x,:). For
- example, in a situation like this
-
- sign -----------> [x][3][6]
- [3][1][2]
- [1][3][4]
-
- on the [x] square you can put only a [18] (for 3x6 - horizontal) or
- a [3] (for 3x1 - vertical), because multiplication is what the sign
- demands that you do. But these squares give you (for your trouble)
- an extra bonus: You are allowed to take one new tile out of the 'bag'
- and use it in that same round, if you wish to do so.
-
- Your are always asked if you want a new tile because there are cases
- that this may cost you (e.g in case you are pursuing the 50-points
- bonus or in case that this may bring in your racks a big value tile
- at the end of the game).
-
- 1.6. EXCHANGING TILES
- ---------------------
- You can exchange as many of the tiles on your rack you want, but
- you loose your turn. Exchanging is not allowed in case you have put
- already one of your tiles.
-
- 1.7. THE END OF THE GAME
- ------------------------
- The game normally ends when the 'bag' empties and no more tiles can
- be put anywhere. It's up to the players to decide when to end the game
- officially (this can happen even before the 'bag' empties). When this
- happens, the sum of the tiles still left on the rack is subtracted
- from the current score. So if one player is stuck with the tiles [60],
- [70] and [80] he/she will loose a total of 210 (=60+70+80) points after
- the game ends (This is a real curse !)
-
-
- 1.8. HINTS
- ----------
- You can ask for a 'hint' during play and the computer will point
- you to a tile you can put on the board, WITHOUT telling you WHERE to
- put it. 'Hint' should not be used in competition games. Using 'hint',
- you also give up your right to enter the Hall of Fame.
-
-
- 1.9. COMMON MISTAKES
- --------------------
- Many people think you can perform one of the 4 operations diagonally.
- You can't! Only horizontally and vertically.
-
- Many people think you can place the result BETWEEN 2 numbers.
- Example:
-
- place 48 (=8x6) here \
- |
- [8] [6] No! Only like this: [8][6][48] or
- [.][.][.] [48][8][6]
-
- 1.10. SOME TIPS
- ---------------
- By playing Mathable (using the computer as opponent) you will
- soon develop your own strategies of playing. You will soon realize that
- the game becomes more exciting at the end (when -say- 6-12 tiles remain
- in the bag). Some tips for the beginners:
-
- 1) Choose tiles and squares to get as many points as you can but
- place them in a way, so as to help yourself put more tiles, targeting
- the 2x and 3x squares. A [90] on a 3x square makes you really happy!
-
- 2) Because your opponent tiles are not hidden, try to play aggressively.
- Don't create for your opponent a nice [9][10] if he/she has a [90]
- to put, not unless you have a [1] (10-9) or [19] (10+9) to spoil
- it for him/her. It is generally a bad practice to put a small tile
- (just for putting it!) which will give to your opponent(s) the chance
- to get many more points.
-
- 3) When the end is near and you give up the hope of finding a place
- to put your big ones (such as [64], [70], [72], [80], [81] and
- [90]) try to get rid of them by 'Exchange'. You surely don't want them
- to be subtracted from your total. Having small tiles in your racks
- (such as [0], [1], [2]) is generally considered as a blessing at the
- end of the game.
-
- 4) It is a good practice to take a look from time to time to the
- 'Tiles Left' (in the 'bag') particularly as the end of the game
- approaches. This way you can see the remaining tiles and find
- out what is the best thing to do:
-
- <i> to put one of your 'small' tiles (with the risk of getting
- one 'big' but useless tile),
- <ii> to pass, or
- <iii> to exchange, hoping that you can get rid of useless 'big'
- tiles sending them back to the 'bag' or (at the best) to the
- racks of your opponent(s), if he/she is not careful as you are.
-
-
-
- 2. P R O G R A M I N S T R U C T I O N S
- ============================================
-
-
- Playing 'Mathable' is fairly easy.
-
- However, you will need a mouse to select the tile you want and
- place it on the board. To do that, click once to select the tile,
- move the mouse until the tile gets close enough to the square you want
- to put it, and then click again to release it. If you make a mistake
- the tile returns to its original position in your rack.
-
- Apart from the tiles, 7 buttons exist on the screen. You activate
- their functions by clicking on them or pressing the corresponding
- underlined letters. These are:
-
- <P>ASS : To pass your turn to the next player.
- HALL OF <F>AME : See the hall of fame. (Remember 3 halls of fame exist,
- for games with 2, 3, or 4 players).
- <T>ILES LEFT : See the tiles left in the 'bag'.
- E<X>CHANGE : To exchange one or more tiles.
- <Q>UIT : To end the game after all the players agree to do so.
- <H>INT : To ask the computer for a hint.
- <O>PTIONS : To
- <i> change the colors of the desktop,
- <ii> choose cursor and tile speed, and
- <iii> toggle sound on/off.
-
- (Inactive buttons are indicated by their dimmed captions).
-
- Finally, a MESSAGE BOX displays useful messages, such as the number
- of tiles remaining in the 'bag' and certain 'Yes' or 'No' questions
- to confirm or cancel various actions.
