Summary
A game that's more fun than it is educational
The Good
It's just fun to play. The cutscenes with the troggles are either lame, strange, or funny depending on your perspective, but there's no denying that the fast paced gameplay is challenging and simply fun.
The Bad
I'm not sure how much it helped my math abilities, but other than that it's a solid game with very few shortcomings.
The Bottom Line
You are a frog who has to eat the correct numbers in the grid, while avoiding the monsters (troggles) that come in from the sides of the screen to eat you and mess up the numbers. For instance, when playing under the factors mode, you have to eat all the numbers on the screen that are the factors of the given number for the level. If it's level 5, all you have to eat are 1's and 5's. Level 12 is tricky, because 1, 2, 3, 4, 6, and 12 are all numbers you have to eat. If you eat the wrong number (say a 4 on the 5 level) you lose a life. You also lose a life for falling victim to one of the troggles (who come in different varieties with differing behaviors).
