A card game where have to build a crossword puzzle.
The game contains 100 cards, each one as one or two letters printed on it. 4 cards are drawn and put on the table in a row. The rest of the cards are shuffled, divided by the players and put in front of them as individual stacks.
On your turn, you draw cards from your stack until you have 7 in your hand and try to add them to the existing words already on the table in a crossword puzzle style. You may cover existing cards (therefore the name of the game); only rows are required to be meaningful words, columns can be any letters you like.
If you manage to create a new word, you score the points according to its length and the next player takes his turn. The game ends when one player has only one or no more cards to play.
