Dicey Operations
This game follows on from Nice or Nasty. You might like to try Dicey Addition before playing this game.
Again, there are several games to choose from.
Find a partner and a 1-6 dice, or preferably a 0-9 dice if you have one. The interactivity in Dice and Spinners can be used to simulate throwing different dice.
Take turns to throw the dice and decide which of your cells to fill.
This can be done in two ways: either fill in each cell as you throw the dice, or collect all your numbers and then decide where to place them.
Game 1
Each of you draw an addition grid like this:
Throw the dice nine times each until all the cells are full.
Whoever has the sum closest to 1000 wins.
There are two possible scoring systems:
- A point for a win. The first person to reach 10 wins the game.
- Each player keeps a running total of their "penalty points", the difference between their result and 1000 after each round. First to 5000 loses.
You can vary the target to make it easier or more difficult.
Game 2
Each of you draw a subtraction grid like this:
Throw the dice eight times each until all the cells are full.
Whoever has the difference closest to 1000 wins.
There are two possible scoring systems:
- A point for a win. The first person to reach 10 wins the game.
- Each player keeps a running total of their "penalty points", the difference between their result and 1000 after each round. First to 5000 loses.
Game 3
Whoever has the product closest to 1000 wins.
There are two possible scoring systems:

Throw the dice five times each until all the cells are full.
Whoever has the product closest to 10000 wins.

Throw the dice six times each until all the cells are full.
Whoever has the answer closest to 100 wins.
There are two possible scoring systems:
- A point for a win. The first person to reach 10 wins the game.
