About Qwinto: Das Kartenspiel, from BoardGameGeek:
Qwinto: Das Kartenspiel is a card game version of the dice game Qwinto. As in the original game, players each have an individual score sheet, and they're trying to use numbers (1-18) to fill in the empty spaces in three rows, which are colored orange, yellow and purple. Within a row, lower numbers must be placed to the left of higher numbers, and no number can be repeated. In the two- and three-space columns formed by the rows, no number can be repeated, but numbers can be in any order.
Aside from the score sheet, the game includes 32 cards, with the cards numbered 0-6 and -2 in four colors (yellow, orange, purple, gray). Each player starts with a random hand of three cards, then four cards are laid in a 2x2 square. On a turn, a player lays a card from their and onto one of the cards in the square, then sums that card and the two adjacent cards, stating this number and the color of all non-grey cards out loud, e.g., "13 in purple and yellow". Each player can then write a 13 in either the purple or yellow row on their score sheet. If the number is less than 1 or all the cards are grey, then no one can write anything; if the active player can't write anything on their score sheet, then they must mark a penalty box instead.
If a player has two cards with the same number, they can lay down one of them, then the matching number in an adjacent space, thus possibly changing the sum drastically. A player refills their hand to three cards to end their turn.
When a player has completely filled two rows with numbers or all four penalty spaces on their score sheet, the game ends. Each player tallies the points for each of their rows: 1 point per number if spaces are empty, or as many points as the rightmost number if the row is full. For each three-space column, if all spaces are filled, then the player scores points equal to the number in the pentagon. For each penalty point, the player loses 5 points. Whoever has the highest sum wins!
