Exponential Invasion, a math puzzler from Danny Perski, is now available from the app store. Featuring a minimalistic presentation and though-provoking challenges, Exponential Invasion should get any good mathematician’s juices flowing.
Exponential Invasion Pros:
- Simple presentation
- Muzak soundtrack and explosive sound effects
- Simple tap controls
- Challenging puzzles
Exponential Invasion Cons:
- Short campaign
- No social gaming network integration
- Moves aren’t tallied in real-time
- Easy to hit progress reset button inadvertently
Exponential Invasion provides two dozen puzzles consisting of gridded areas full of blue towers and white attack numbers. Success is measured by the number of moves required to combine the white numbers into integers greater than the blue towers, exploding them and clearing the path for victory. Larger numbers can subsume small numbers by moving to adjacent spaces. Failure to complete the puzzle in the fewest moves will only earn two bombs and a note indicating how many fewer moves you should be able to finish in. Meeting the target explodes all three bombs. It’s unclear what needs to occur to only earn one bomb or fail to earn any, which makes the three-bomb element an odd choice given its apparent binary nature. Regardless, puzzles aren’t too difficult and the entire game can be completed in about an hour, leaving us clamoring for more puzzles.
Graphically, Exponential Invasion uses a simple, black-and-white theme with blue towers and red and green colors to indicate selectable grid possibilities. The soundtrack has a muzak quality, and explosion sound effects are used when a tower goes down. Controls are purely tap-based, requiring you to select a source cell and target. The gameplay has a certain allure that we really enjoyed, though replay value is limited by a short campaign and no social gaming network integration. We were also disappointed that our moves weren’t tallied in real-time as we played, leaving us to count on our own or wait until completion to see how we did. A poison symbol on the menu screen is easy to accidentally tap, which will reset all progress. A universal app with cloud syncing across devices, Exponential Invasion is a 3.5-Dimple app that’s a little pricey at its current $2.99 tag.
