Introducing Time Killer 4-in-1, the perfect app for killing a little bit of time while waiting at the doctors office, waiting on the cable guy, etc.

Featuring these four oddly addicting and fun mini-games:

Number Guess – You pick the lowest and highest numbers, and the app chooses a random number in between (including your numbers). Then you guess until you get it right, with a little help from the app.

Pen Click – Simply click and click and then click some more. Complete with a full running tally of how many clicks you've actually made and real pen clicking noise.

Shoot – Release some stress by shooting a background of your choice (using camera or photo album) with bullets or paintballs! Also includes a fully automatic mode and realistic sounds!

Math – 10 question quiz as fast as you can go! Simple addition and no answer is over 100. Keeps your best score saved so you can show it off or just try to challenge yourself.
