Some of the best math games are the simplest, and so it is with Dino Numbers, a basic save-the-cows-from-the-dinosaurs video game for kids brushing up on arithmetic. As with many of these applications, this one will look decidedly basic compared to, say, World of Warcraft, but a crudely rendered tyrannosaurus can teach addition as well as anyone.

Hankering for more sophisticated play? Soccer Math has downright impressive graphics and design. Basic arithmetic, percents, fractions, decimals, and more are tested in this well-crafted software. Get the right answers and you'll dribble past well-rendered opponents, shoot on the goal, or bend it like Beckham.

Fortunately, the company behind Soccer Math has an offering for younger minds too. Penguin Cold Cash features, well, penguins and cold cash. Kids can learn the math behind money transactions as cute penguins surf through icebergs, catch fish, and try their flippers at ice hockey.

Of course, cool graphics are just one way to win the heart of a discriminating gamer. Valgetal, a simple Tetris-like math game, is as rudimentary and transfixing as the original procrastination tool — except that players strengthen their basic math skills as they control the falling blocks.

Personal Trainer: Math makes math practice portable with this collection of games and exercises for the handheld Nintendo DS. The "play" aspect of this game is more limited than with other options, but it's habit-forming nonetheless. The game also tracks a player's progress over time, so improvement can be easily measured.

Nintendo DS users can also blast their way to better basic math skills via the popular Math Blaster in the Prime Adventure, in which elementary-school-aged players save the galaxy through a series of colorful mini-arcade games. The multiplayer battle mode allows up to three additional players to compete against each other — so the game can become social as well.

Sheppard Software offers more than two dozen free online games, from basic math operations to pre-algebra. These include the standard race-against-the-clock types of problem-solving as well as offerings such as Add Like Mad, in which players pick the two numbers from many whose sum equals a selected value. (The company also offers a handy daily pop quiz for a more pared-down, school-like approach.)

Math video games tend to involve boyish pursuits, be they shooting aliens or, well, shooting other things, and Mathamagica has a bit of that. But this collection of basic yet appealing mini-educational games also includes cute critters and fanciful fairies and mermaids — a step toward appealing to girls, ostensibly. A tip of the tiara for that.
