This fun, addicting logic puzzle is based on the "Where's My Water" format. It features first-rate Disney characters and music from Disney's Phineas & Ferb series. The idea of Where's My Water is simple. You use your fingertip to guide water in its different forms (ice, steam, and liquid) through different levels, to achieve a goal. The game feels a bit like "cut the rope" because you have to plan your tunnels carefully, so enough water is left to reach your goal. This is a great exercise in higher order thinking. In addition, there's a touch of reading comprehension practice, because each puzzle comes with a mini-story that is both narrated and presented in text. Your initial investment of $.99 gives you 80 puzzles, and free updates are promised. But there are other in-app hooks in this game. In the story, Agent P becomes stuck in one of his transportation tubes after being summoned to the headquarters of Major Monogram for a mission briefing. Your goal is to lead Agent P back to the OWCA headquarters. Interesting puzzle elements include lasers to help change water to different forms -- a heat-inator to turn water into steam or ice into water, a cool-inator to turn water into ice and the celebrate-inator vacuums up water or steam. The game also features gnomes to collect and bonus levels to unlock. Monetization. Pay attention to the way this app is monetized. You buy the first level for $.99, which gives you 80 puzzles. Additional sets of puzzles cost $.99 each as in-app sales, or you can unlock the full series for $1.99. So the true cost of this app is $2.99. There are a lot of padlocks in this game. In addition there are frequent facebook "like" pings. All in all, this is an excellent quality, but highly commercialized app. As long as you keep an eye on eye on your pocketbook, you'll have a great time, and stretch your brain, too.
