othello is good.yahtzee.

Board games are difficult, as most of them have pieces that the tykes will want to grab.

Aside from that concern, though, a great one is Diamant. It doesn't take a lot of concentration and the decision point can be new each turn - no real long-term strategy is necessary.

Another good one is Set, although technically it's a card game, not a board game. This is another one where each turn is different, and arguably one plays better when NOT concentrating. Some would dispute that last point, though.

I should have asked: how many moms would play at once?
