## 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 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!
