It says it comes with “100 number cards chosen for optimal fun.” So does that mean it’s just 0-99? Or are some numbers missing or doubled?

Hello! For "optimal fun", we've chosen our 100 number cards so that there are more of the easier-to-use lower numbers, such as 0 - 10, and we also removed some of the more difficult-to-use larger numbers, like 85. We've also left out many tricky prime numbers, like 97. We've found that doing this makes for a better mental math experience!

Is there always a “solution” on the “board” or are there times when everyone is stumped and you need to re-deal some cards?

Given the huge number of ways that equations can be made, there is almost always a solution somewhere on the board, and it's usually a pretty straightforward one. However, if for any reason players are stumped and can't spot the equation, the rules stipulate that you can deal 3 more cards to the center of the table. With 12 cards instead of 9 now on the board, it's incredibly unlikely there wouldn't be an equation somewhere in there.

Is it possible to play with just addition and subtraction, or do my kids have to be familiar with all the operations?

Hi! It’s definitely possible to play that way. I would also just recommend that you remove all cards over 30 from the deck so that it’s easier and more likely to be able to make equations with just addition and subtraction.

Would this math game be good for Freshmen in Highschool?

Yes. This game is great for any age group. You just customize for age.
