FETCH! Lunch Rush does not have much of a story line, but it is a silly and fun take on basic addition and subtraction drills. One to four players take turns at the same tasks. They solve math problems quickly to count the number of pieces of sushi needed to serve a movie crew, which includes friends of Ruff Ruffman, the main cartoon character from the PBS show Fetch. The catch is that instead of a keypad for number entry, players have to use the camera on the phone or iPad (first generation iPads will not work) to select the right answer from one of ten paper clues printed out from the PBS website before the first game play. Game play can be fast, if numbers are close by, or wildly active, if the numbers are scattered around a room or all over the home.

As players progress through the levels, the math drills get harder. Starting with memorization, they build toward two-digit subtraction problems. The latter are still fairly simple. No operand is higher than 20, and no solution is higher than 10. Players are promoted to new levels after they solve problems quickly and accurately enough. My first-grader is enthusiastically still pursuing the elusive "Top Dog" level. The graphics are nifty-the sushi appears in 3D over the number card when players hold the camera up to it. Play also inspired my children to revisit the PBS show on which the game is based, an old favorite whose videos are still readily available on the PBS website. The game is very useful for simple math practice (one can never have too many fun ways to practice math facts). Even if play is not widely varied, young players will enjoy it.
