When large spikes fall down, move left, right, or remain in the center as required. Always watch the top of the screen to give you enough time to anticipate the correct direction and position to use. However, before moving to evade the next set of spikes, make sure you are clear from hitting your current obstacles. There are four basic ways to avoid spikes: moving your blocks to the left then moving to the right (and vice versa); splitting your blocks apart; and remaining in the center. They key to success is timing those four moves based on the pattern of spikes that must be avoided.
