Qwadro is a roll and write game for 2-4 players, 10+ years, playing time about 20 minutes.
On his turn, the active player rolls 4 dice and is entitled to 1 re-roll.
All players then write the sum of 2 dice on their player sheets.
The colors of the dice determine the row or column in which the number is entered.. The numbers must be entered next to already entered numbers.
The active player may enter a 2nd number as well, but must use the 2 dice that he did not use in the 1st entry.
Numbers in rows and columns must go from lowest to highest - left to right and top to bottom..
If a player has 4 of the same numbers orthogonally connected, he gets bonus points and may no longer enter that number.
If a player cannot enter a number, he gets negative points.
The player with the most points wins.
