Our game is beautiful! Everything is constructed squarely and well, with hinges that work smoothly and a latch that keeps the lid snugly in place when closed. The lining on the dice-throwing area looks great, too, as does the fabric beneath the base that prevents the scratching of fine furniture. And the movement of all the numbered pieces--and the way that all of the edges meet up in both the open and closed positions--is dead on. If treated respectfully, this game should stay beautiful and last for generations; but I can imagine that young children left on their own could damage it easily by forcing the lid past the 90 degree "open" point or by twisting it, so keep that in mind.With the 12 number game, you can play using standard addition rules, or you can allow multiplication of the dice, too! So a 4 and a 5 on the dice could be 9 or could be 20--your choice. That makes it more fun for adults, and it adds to the educational value for kids.And since there are numbers visible in both the up and down positions, it helps in keeping up with your math--plus allows two players to play the long game (where one player tries to get all of their numbers down as the other player tries to get them all up--taking turns until all the numbers are either up or down).This game is attractive enough to keep out full time--which I plan to do. It's a simple and elegant design. But a craftsperson or artist might consider decorating it, too. Even if you buy the game as a crafts project, it's a great value.
