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 are seen in the roll.
Method 1: Summing up values that are not shown:
Method 2: 21 minus each unique shown value:
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.
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!
