Welcome to

2nd National ArithmetEQ Challenge 2010 @YSS


Do Take Note…

• All participants, please note – You are required to register at the registration

counter.– Sit according to the table assigned.– Each player will pick a number card from the helper

which will determine who starts the game and the sequence of the other players.

– Sit in such a way that the game will be played in a clockwise manner.

– Lastly, do remember to switch off or put all handphone on silence mode before the start of the competition.


About ArithmetEQ

• Consist of a board with premium squares• 150 tiles that are printed on both sides (numbers

or operators on one side, equal sign on the other side) and are placed in the bag

• Numbers (0 – 9)

• Mathematical Operators


About ArithmetEQ• Mathematical Operators

- Addition - Subtraction

- Multiplication - Division

- Power - Fraction

3 ^ 2 = 9 1 Γ 2 Γ 3 =

- Square Root - Brackets

3 (2 + 4) = 1 8

- Decimal Point


How to play the game

• Each player will draw 7

tiles from the bag.

• The 1st player will use 4 or more tiles to form an equation on the board to read either across (left to right) or down, with a tile on the centre square


How to play the game (cont..)• After an equation is placed on the board,

the player will replace the number of tiles that are used from the bag and place them back on his rack.

• Play in sequence and on each turn, the players have a choice of exchanging the tiles, passing or placing an equation on the board.

• All tiles played in any one turn must be placed in each row across or one column down the board.


How to play the game (cont..)

• If the tiles touch each other in adjacent row, they must form complete equations.


How to play the game (cont..)

The game ends • when all the tiles have been drawn from

the bag and 1 of the players has used up all the tiles in his rack.

Or• all the players have passed once in the

same turn. (Exchange of tiles is not a pass)


Take Note…

• Always ensure that there are 7 tiles on your rack as long as there are still tiles left in the bag.

• Any player may use their turn to exchange ONE or ALL their tiles on their rack. They will then miss a turn and have to wait for the next turn to play.


Take Note… (cont..)• Each player has to form an equation during his turn.

- 1st player places “ 2 + 3 = 5”.

- 2nd player places “5 =” in front of the tile “2”.

This is correct as “5 = 2 + 3” is an equation.

- 3rd player places “= 5 . 0” after “= 5”.

This is not allowed as 5 = 5.0 is not an equation.

Scoring • The score value of each number or operators

are indicated by a number at the bottom of the tile.

• The blank tiles has no score value but can be used as any number (0 – 9) desired.

• There are 6 blank tiles altogether.


Scoring (Cont..)

• Multiply by 2 to the score on the tile placed above it and add up the total score

• Multiply by 3 to the score on the tile placed above it and add up the total score

• Add up the score on the tiles and multiply by 2

• Add up the score on the tiles and multiply by 3

The following shows the premium squares on the board.


Scoring (Cont..)• The score for a turn is calculated by adding all the

values of the number on the tiles plus the premium values resulting from placing on the tiles on the premium squares.

Total Score = (1 + 2 + 1 + 1 + 1) 3

= 18 (The tile “3” falls on the “ 3 x eqn” square. Hence the total score will be the sum of all the values multiplied by 3)


Scoring (Cont..)• Number and equation premiums count only on the

turn in which they are played. On later turns, numbers already played on premium squares will only be counted at face value.

• The 2nd player placed “6 x” and “= 8”• Total score for the 2nd player = 1 + 2 + 1 + 1 + 1 = 6 (Tile “3” on the premium square is placed by the 1st player, hence the sum of the score x 3 will not applicable to the 2nd player)


Scoring (Cont..)

•The 3rd player placed “2 +” and “+ 3 = 6”• Total score for the 2nd player = 1 x 2 + 2 + 2 + 1 x 2 + 1 + 1 = 10 (Tile “2” and “3” falls on the “ 2 x term” square, hence the score value of these 2 tiles will be multiplied by 2 and then add up all the sum to find the total score.)

• The 2nd player placed a blank tile which represent the number “1”, hence the number on this particular blank tile will be fixed as “1” throughout the game.


Scoring (Cont..)

Bonus Score:

• If the player uses ALL the tiles on his rack in a single turn, in addition to the regular score for his turn, he scores an extra 50 points


Scoring (Cont..)

Unplayed tiles: • When the game ends, the final score of

each player is reduced by the sum of all his unplayed tiles.

• If one player has used up all his tiles, his score is increased by the sum of all the unplayed tiles of all other players.


Scoring (Cont..)

• The player with the highest final score wins the game.

• In case of a tie, the player with the highest score before adding or deducting unplayed tiles wins.

• Decision of the judges is final.
