Simple game once you learn the rules and play for 5-10 minutes.  Each tile has one of six shapes, in one of six colors, five tiles in their hand.  Each turn players can place (or trade in) their tiles.  If you place, you must place tiles so that you form a row of either:  (1) same color tiles, with no shape repeating (meaning the maximum row size is six); (2) same shape tiles, with no color repeating.  You get 1 point for the length of the row formed.  For example, if you add two tiles to a row that was 3 tiles placed by another player, you would get 5 points.  As long as you place tiles in a straight line and obey the above rules, you can form more than 1 row, and get points for all.  For example, if you add a tile to the end of a row of 3, you get 4 points for that, and if you place a tile below the 4th tile in that row (the one you added) you get another 2 points for that new 2 you created.  In other words, the scoring works like scrabble, in that as long as you place your tiles in a row, you can form more than one scoring line -- more than 1 "word" in scrabble terms.  If you form a color row with all six shapes, or a shape row with all six colors, you get 12 points, not 6 - that is called a "quirkle."
