This game is called "Klondike Bill" in Tim Hartnell's book. I've called it "Dice Poker"; but I don't know the correct name! There is a solitaire game called Klondike solitaire (but this isn't it).

If anyone recognises the game, please post a message with the game's name!!!
Anyway, name aside, the game is very simple, you "roll" 5 dice (and can see 2 of the computer's dice); then you make a bet and finalise the hand. Neither player can discard / re-draw. The deciding of the winner is also very simple, Straights are worthless; pairs, three--of-kind etc are where it is at.

The best hand is five-of-a-kind (but five x 1 is equal to five x 6)!
Despite, all the above the game is enjoyable.
cheers
