Problematic particles is a simulation / puzzle game in which the objective is to move the particles from the particle generator(s) into the goal(s) through a series of obstacles. To do this, you place gravity wells by tapping on the screen. Using the slider, you can change the power of the well - you can make it repel or attract particles, and you can change the degree to which the well repels or attracts. After you've placed all of your gravity wells, you press the play button. After this, the particles are generated, and (hopefully!) they are directed towards the goals. You are given a high score based on the time at which you completed the level, and given a rating out of 3 stars for how well you did in scoring the particles.
