Take points, give points: Both can lead to success in Charidice.
On a turn, roll the six dice up to three times. Each die features the numbers 1-6 in six colors, and after you stop rolling, you score either all of the dice of one color (as long as you have at least four dice of that color) or one die of each color. Get certain combinations — such as a straight of 4-6 numbers in the first case or a 4- to 6-of-a-kind in the latter — to score bonus points.
Whatever you don't score gets scored by the player to your left, with 5s and 6s scoring double for them. Once during the game, before your right-hand neighbor takes their third roll, you can ask them for "the greatest of gifts", and whatever they give you that turn is doubled.
Whoever gives away the most points receives 20 points at game's end, with the bonus rising to 30 points if they gave away 60+ points. Yes, you may be rewarded for your charitable givings, but is it better to give than to receive?
