**Game suggestion 2.9** is also about logic, as the game suggestion is based on binary numbers, which only consist of the digits 0 and 1 and are used in the binary system. This system is the basis for almost all modern computers and digital systems. The system has fascinated me since my youth and I am delighted that it is now part of my following game proposal:

A selected player of a game group, which can easily consist of more than 10 players, creates an arbitrary dice chain with up to 18 dice (**see picture A**).

Although the dice chain was created arbitrarily, it represents a specific number (in this example it is a number that is even greater than 2 billion, namely the number **2,521,652,320**), which can be systematically determined by the players.

To do this, the players first mentally divide the dice chain shown into 6 individual dice chains, each consisting of 3 dice (**see image B**).

The binary numbers, which consist of the digits 0 and 1, are represented in this game with GAME & MORE dice (a die without holes stands for the digit 0 and a die with holes stands for the digit 1).

All players are given a piece of paper and a pen to write down the codes of the binary numbers 0 to 7 (see left-hand column in **Figure C**). The numbers in the other two columns do not have to be written down, as in this game only the numbers 1 and 2 are placed in front of the numbers 0 to 7 (see centre and right-hand columns in **Figure C**).

As you can probably already imagine, the respective arrangement of the 3 dice within a small dice chain plays an important role in this game:

The numbers in **column 1** apply to the case where all 3 dice have been positioned **straight**.

The numbers in **column 2** apply if all 3 dice have been positioned **at an** **angle**. In this case, only the 1 is placed before the digits 0 to 7.

The numbers in **column 3** apply if all 3 dice have been positioned **straight and at an angle**. In this case, only the 2 is placed in front of the numbers 0 to 7.

The players should memorise this well so that they can start to determine the result they are looking for as follows: First, they look at the dice chain again and again and then write down the corresponding numbers of the 6 small dice chains on their piece of paper: 25 2 16 5 23 20

If you now push these 6 numbers together and place a dot every 3 digits from right to left, you will already have your result – the correct result in this example would be: 2521652320 = **2,521,652,320**

The level of difficulty of the game can of course also be changed, for example by dividing the dice chain into 6 small dice chains with 3 dice each (see **picture B**), or by making it significantly shorter.

The first person to determine a result calls out “1” to the group and writes the number 1 on their piece of paper. The next person to determine a result calls out “2” and writes the number 2 on their piece of paper. This is done in the same way for the other players.

Once all players have written down their results, the results are compared and points are awarded. The player who was quickest to determine the correct result receives 3 points and every other player who also determined a correct result receives 1 point.

**Have fun and good luck!**
