Polar Bears are Good Fathers
That's where the titular "Daddy Cool" comes in. See, polar bears (at least according to the game) are good dads and go ahead to check out the safety of the ice so their young don't go for an unexpected dip in frigid waters.
After you start your turn by rolling the six custom dice (three sides have ice floes on them, three sides are blank), you move Daddy Cool forward as many spaces as floes on the dice. You then set those dice aside (the ones that helped you move) and make the decision whether you want to roll again or stop.
If you stop, you move your polar bear cub up to the floe that Daddy is on. Rolling again means you keep moving him forward and setting aside dice.
First, there are two ice floes which are already cracked (they have a "Danger!" sign on them). If Daddy Cool ends a move on one of these spaces, you must roll again.
Second, when the last-place cub has two (or more) floes behind him, one of them is taken out of the game and the rest of them are added to the front of the track.
The Edge of Kid-Gaming Perfection
A couple of notes about age and number of players: I've had good success with younger players in a mixed group (adults and kids) -- my three-year-old can play this with some help. But although the box says 2 to 6 players, the game works much better with 3 or more.
