A game for kids who would like to get better at arithmetic operations, decimal system and numbers in overall:
European Championship
- Only materials needed for this game are a twelve-faced dice, pen/pencil and a piece of paper.
- Game consists of encounters between two players.
- In each encounter players roll the dice four times in order.
- Outcome of a rolled twelve-faced dice is like the following:
- For every player only ambition is to write the biggest possible four-digit number.
- Difference of players’ four-digit numbers decides the winner.
Scoring of the game
Player with the bigger number would get:
- 4 points if the difference is a four-digit number.
- 3 points if the difference is a three-digit number.
- 2 points if the difference is a two-digit number.
- 1 point if the difference is a single-digit number.
If the difference is zero; meaning that the numbers are equal to one another, then both players get no points.
Every encounter finishes when one of the players gets to 7 points.
League
In case there is enough number of students, it is possible to construct a league version of the game that finishes after playoffs. For instance if there were 20 students we could divide them into 4 groups with 5 teams. In each group every player would play 4 games and after the group stage group leaders would go onto the playoffs where the champion can be decided after semi-final and final games.
World Cup
In this version of the game players would roll the dice three times and write the biggest possible three-digit number. Although this time winner gets to be decided like following:
- If the difference is odd, biggest number wins.
- If the difference is even, smallest number wins.
- Winner gets 3 points as loser gets nothing. Differences are kept as averages.
- If numbers are the same, players get 1 point each.
