Based on the popular series from Scholastic books, I Spy Challenger! consists of four minigames that challenge your identifying and matching skills.

In Hoop Drop, you drop items like flowers and toy vehicles in circles that contain similar items. In Riddle Round-Up, you must solve 36 different puzzles by scrolling for items scattered across multiple screens. With rhyming lists of objects and photorealistic graphics, the puzzles here are most like those found in the best-selling books.

In Grid Grab, you are presented with a row of objects, and must choose the matching row in the grid below. Be careful -- the hidden row may be horizontal, vertical or diagonal.

In Match Attack, you shoot items like hearts and stars at identical items scrolling across the screen. While the other minigames emphasize concentration and observation, Match Attack is more like a traditional shooting/matching video game puzzler.
