Each player in Twenty One receives a different score sheet at the start of the game; each sheet has five horizontal rows with six colored dice pictured in each row, and while the numbers are identical in each of the rows on each sheet, the arrangement of colors differs.
To score points, a player needs to fill these dice with numbers, but they have to fill (or mark off) all six dice in a row before they can move to the next row on their score sheet — and to write numbers on their sheet, they'll have to depend (at least somewhat) on the luck of the dice.
On a turn, the active player rolls six colored dice that match the colors depicted on each score sheet. They must keep all 1s that they roll, but they can choose to reroll all non-1 dice twice. After the second roll, all players can use the rolled dice to fill one or more of the dice on their sheet — but only if the die of the matching color shows a value equal to or less than what's on the score sheet.
