I'm not exactly sure what those terms mean, but I can tell you that the box the game comes in is a very heavy duty cardboard and deep enough to hold all of the game pieces. In my experience, rectangular game boxes can tend to break down on the corners. This "Squirrel" game has irregular angles so there is no stress on the corners. The box does not crush easily because it is a thicker quality cardboard than the average board game.
Well the acorns are small. So if the 2 and 1/2 year old still puts items in their mouth I would say no. Also if their is a younger child in the house, no as well. But my son at 2 1/2, I would have bought it an played with supervision together. Hope this helps :)
I bought this for my 2.5 yo. The game is simple, no words. Turn-taking was the hardest concept for my daughter at that age. It does have small Pisces so not for little ones that still put everything in their mouths.
There are different colored acorns and each player has to fill their "log" with one acorn of each color (blue, red, yellow, green and purple). There's a spinner you spin to see which color you can get. There's also other things on spinner like steal an acorn from another player, put your acrorns back, and. lose a turn. Real simple but great for kids.
