The quick-playing dice game of QWIXX where everyone participates, on everyone's turn. Players have a scoresheet with the numbers 2-12 in rows of red and yellow and the numbers 12-2 in rows of green and blue. To earn points you try to mark off as many numbers as possible, but you can only mark off a number if it is to the right of all marked-off numbers in the same row.

On a turn, the active player rolls 6 dice: 2 white and 1 of red, yellow, green, blue. Players can choose to mark off the sum of the 2 white dice on one of their four rows, the active player then can choose to mark off the sum of one colored die and one white die in the row that's the same color as the die. The more marks you make in a row, the higher your score for that row. However, fail to cross off a number when you're the active player, and you must mark one of 4 penalty boxes on your scoresheet. If you mark off the 2 or 12 in a row and have at least 5 numbers marked in that row, you get to also mark off the padlock symbol in that row, locking everyone else out of that color.

When a player has 4 penalty boxes marked or a second color is locked, the game immediately ends. Players add up their points for each color, sum these values, then subtract 5 points for each marked penalty box. The player with the highest score wins.
