## Inverted Dice

Inverted Dice is a challenging tactic dice game for smart adults and curious children.

The game introduces a new way to look at dice rolls – a way to regard five normal six-sided dice as one big twenty-sided die (with some odd probability properties).

Normally, you would throw some dice and calculate the sum of the numbers being shown. In this game, you calculate the sum of the numbers NOT being shown.

Such a roll is called an inverted dice roll and is made with standard six-sided dice. You need five dice to play.

The structure of the game is a bit like the one in Yahtzee, with a similar score chart and three rolls (or fewer) per turn.

Number of players: 1 - 5

Game duration: 10 mn

Complexity: 3 / 5

### Rules summary

## Overview

The *structure* of the game resembles that of *Yahtzee* (and variants). Players take turns trying to achieve the scores in the table (**1** to **20**). Maximum 2 rerolls per turn.

A result can be scored if it has not previously been scored by the player. If the player fails (after three rolls), a score must be crossed out.

The game ends after 20 rounds.

## Inverted dice sums

The result of a roll is the sum of the values that * are not seen* in the roll. However, there are

*two*ways to find the result of a roll, since it can also be calculated as

**21**

*minus*each

*unique value*that

*in the roll.*

**are seen**## Examples

**Method 1:** Summing up values that are * not shown*:

is **5** since **+** is **5** (neither nor is shown).

**Method 2:** 21 *minus* each unique * shown* value:

is **15** since **+** **+** is 6 (only count each shown value *once*), and 21 – 6 is **15**.

is **18** since **+** is 3, and 21 – 3 is **18**.

is also **18** since **+** is 3, and 21 – 3 is **18**.

is **10** since **+** is 11, and 21 – 11 is **10**.

## Turn

First, all five dice are rolled.

Then, the player has up to two rerolls to obtain a desired result (not previously scored by the player). Click dice to select them, and button to reroll.

If the result after three rolls is *not* available in the score table, the player scores 0 points that round and must choose a score to *cross out*.

## Scoring

At the end of the twentieth round, sum up all the scores you managed to achieve.

In addition, there are bonus awards:

If you have all scores from **1** to **5**, you get 50 points.

If you have all scores from **6** to **15**, you get 50 points.

If you have all scores from **16** to **20**, you get 50 points.

If your total score is 290 or higher, you earn the *Inverted Master* achievement.

If your total score is 360, you earn the *Inverted Grandmaster* achievement.

The player with the most points wins!
