Don't know a THING about those, but I DO know several "ordinary" games that reinforce/use basic math skills:
Monopoly - adding and subtracting larger numbers, making change/working with money
PayDay - adding and subtracting larger numbers, making change/working with money
The Game of Life - adding and subtracting larger numbers, making change/working with money
Yahtzee - multiplication, adding larger numbers
GeoBoards - geometry concepts
Tangrams - geometry concepts
Pentominoes - geometry concepts
Clue - logic, deduction, problem solving
Chess - logic, deduction, strategy, problem solving
Rack-O - sequencing, greater than/less than
MasterMind - logic, problem solving
Battleship - grid/graph coordinates
My go to resources for math games and activities are the books Family Math and Family Math for Middle School. Some nice games and activities can be purchased from the Boxcars and One Eyed Jacks folks, too. I like these because they don't focus on just one skill or one skill level. They cover a wide variety of skills and even I sometimes find some of them challenging.
We often make up our own games. One the kids really like is Combinations. Choose a target number. Deal out four cards. Using addition, subtraction, multiplication and division, try and see how closely you can come to that number. Score 1 point for each number off from the target score. After 5 rounds, the player with the lowest score is the winner.
All this to say that I don't think you need to spend a bunch of money on games specifically for MATH, when you probably have games that can be used as math games already in the house.......
