The iPad crashes sometimes while playing or opening games, you can prevent apps from crashing on the iPad, follow the simple steps below

• Remove all apps from Multitasking. Double tap the Home button to bring up the Multitasking bar. Tap and hold any icon until little red -s appear in the left corner of each app.
• Delete all those Multitasking applications by tapping on the red minus thingy on the icon. This will not delete the application on the iPad, this only removes them from your recently used apps.
• Ok now that your recently used apps are all cleared theres one more thing we need to do. We need to restart the iPad, press and hold the Sleep/Wake (power button at the top) button for a few seconds until the slide the power off thingy appears. Slide to power off. Now turn it back on by pressing and holding the Sleep/Wake button until the Apple logo appears.
• After these steps you will be able to play games on iPad, this should work with any app or game that requires every single ounce of power from the iPad to run smoothly.
