Ballistic Wars (by Easy Only! Games) is sort of like marbles, with some fancy graphics and UI thrown in to the mix. Your goal is to “defuse” bombs set up by a mad professor – and you do so by clicking on your troops, setting up where you want them to go and at what speed.
Contrary to what you’ve been taught, bumping bombs actually defuses them. There’s a lot of different types of troops, and the game does a nice job of slowly easing you in to each new type (and to the gameplay overall). [via ]
