These discs are really easy to throw and really easy to see.  They lay flat on the bottom with the number side up.  But there is the problem:  the numbers are actually stickers on the plastic.  So guess what happens after a few dives with them.  The stickers come off!  There are 3 games listed on the package:  1)See who gets the most discs; 2)See who gets the highest number of points on the faces of the discs (which you need to know how much each is worth and the stickers coming off doesn't help that); 3)See who can come up with 7 points first.  We also came up with one more since we bought 3 sets:  See who can get 3 matching ones first.  They are really fun to play with but they should have numbered them permanently.
