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 all unique values that are seen in the roll.

Examples

Method 1: Summing up values that are not shown:

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

is also 5 since + is 5.

is 6 since + + is 6.

is 15 since 4 + 5 + 6 is 15.

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!
