game rules

Abaku is a numeric game for 2 to 4 players. Everyone who knows, that one and one gives two can play it.

The players are using playing tiles to create numeric operations on the playing board. Addition, subtraction, multiplication, division, squares and cubes of whole numbers and square and cube roots of whole numbers are allowed. The player wins over the other players – calculators thanks to the proper combination of each tile’s value and strategic use of premium squares on the playing board. The aim is to get more points than the others. The one who will enjoy the victory must show good combination, logic, strategy, memory and certainly a bit of luck as well.
Abaku is an effective supporting instrument for teaching mathematics.
Numeric operations are created by adding (horizontally or vertically) one or more tiles to tiles already lying on the board. Newly created numeric operation must contain or adjoin one or more tiles lying on the board. Numeric operations must be legible from left to right and from top to the bottom.

Description

1. The starting player makes the first move by placing vertically or horizontally two or more tiles on the board so that one of them lies on the central square. The tiles cannot be placed diagonally.

2. The player`s turn ends when time runs out for a move, when a move is made, when an empty move is made or when a tile is exchanged. After the turn ends the points are counted and the player refills with more tiles from the bag.

3. Each player must directly join the placed tiles with his own tiles. The tiles must always make a number combination as per the rules. They can be laid both horizontally and vertically. Every newly placed tile and the tile already lying on the board must together
create or be a part of new combination. The player gets points for every combination created in the given turn. 4. The structure created from these combinations is valid only for the actual round. For the following rounds it becomes a simple collection of tiles that can be randomly combined and used in other combinations. Combinations must be readable vertically or horizontally.

5. Combinations are created by:
o Adding one to five tiles to those already placed on the board (see Turn 2, 3, 4, 5, 6).
o Applying a combination across the tiles on the board. This new combination must include one or more tiles already on the board or should be adjoined with one or more tiles already on the board (see Turn 3, 4, 6).
o Applying a combination parallel to the tiles on the board (see Turn 5, 6).

6. A player on turn has three options: place the tiles on the board; change his tiles; skip a turn. He can choose only one of them at a time.

7. Zero: It isn’t possible to start a new combination with zero. Zero cannot be added, subtracted and cannot multiply or divide numbers. Zero cannot be the final result of a combination.
o If a zero tile is part of a combination, its newly created addition doesn’t have to represent a combination. As such, the player gets no points for it.

Finishing the Game

1. The game ends when the players tile bag is empty and one of the players uses the last tile.
2. A player sends an empty turn three times in a row (failing to play within the time limit for a move also counts as an empty turn).
a) If there are any tiles left in the bag, he loses by default meaning he can’t claim the victory.
b) If the bag is empty, the game is ended correctly. If there are more than two players then the player must wait for them to end the game. In any case he can claim the victory if he has more points than the rest at the end.

Points
1. The number shown on each tile corresponds to their actual point value.
2. Final number of points is a total of point values of all tiles used in one turn. A tile that becomes a part of more combinations in one turn brings its owner points for each one of them. BUT: In numeric operations combined of the same numbers will be counted only once (for example: 9²=81, 9-8=1).
3. Bonus is valid only for the given turn (when a tile is placed on it).
a) Number bonus doubles or triples the tile’s value.
b) Operating bonus multiplies (two or three times) the number of points gained by a total of all tiles used in the combination but only when one of the tiles is lying on a bonus square.
4. The player who ends the game gets extra points. These points are a total of all tiles remaining with the other players when the game ends. These players have subtracted their individual remaining tiles from their final number of points.
5. The player with the highest total number of points at the end wins.

7 reasons why abaku game
Viral phenomenon

Not advertised or promoted whatsoever, Abaku gained stable popularity on the largest gaming portal in the Czech Republic within a short period of time. It is the only brand new game that has managed to line up with the traditional popular games and succeeded to keep its position.

Comprehensibility

Abaku can be played all over the world in its present form with no geographical modifications or changes needed (unlike Scrabble, for instance). One form – one set of rules – one world.

Education

Enhancing numeric, combinatory and logical skills, Abaku rapidly increases the ability of players to improve their score from game to game. Proved and tested, the game is supported by the Unity of Czech Mathematicians and Physicists and Faculty of Science, Charles University in Prague. A board game, Abaku is likely to win support from educational institutions and schools.

Complexity

The game – in its simplicity – is quite complex. The austerity of numbers may easily lead to a conclusion that the game is boring. A gentle element of chance when choosing random series of numbers and constantly changing the playing field turns the game into a must-to-have piece.

Motivation

Players receive points for each numeric operation newly created in the given move – both for the intended operations and operations emerging “out of blue”, i.e. primarily not intended by the players themselves.

SIMPLE EXAMPLE

On the board, there is a structure of

(72+9=81,72:9=8,7-2=9,9-8=1)

intending to create 1+99=100

the player (having numbersin their tank) adds numbers

The software, however, additionally identifies other newly created operations:
729:81=9 and 98+1=99 and 81:9=9 and 1x9=9 and 19-9=10 and 9:9=1...

All these operations are graphically revealed and the player rewarded (both for the intended and unintended operations). This is both the biggest motivation for the players and the educative point of the game – the player learns new variations of the operations in real time, during the play, on real examples.

Note: This sample situation is not unreal; numeric operations like this one are common and applied by regular players.

Perfection

Natural characteristics of numbers provide for a sufficient background for designing a perfect gaming board, bonus options and certainty in the course of creating the game rules.

As mentioned before, we are thinking of creating the game as a combination of a classical board game and electronic board game with a gaming board recognising the value of the playing tiles (by implemented chips) and counting and displaying the score after each move on a small window attached to the board; like in bowling where players can focus on the game while the computer counts their score.

POSITION

Abaku is the best numeric game in the universe. We might dislike it, we might even disagree with it, but that's pretty much all we can do about it.
