### A great way to learn math

This is a great math game that teaches the concept of the number line. This is a definite upgrade from the original iPhone app - the graphics have all been re-done in higher resolution, and this game looks great. The controls are nice and responsive, and best of all, it's free. What more could you want? I would strongly recommend this game if it cost 2 or 3 dollars, but at free it's a no-brainer - you really ought to pick this one up!

### Good app, kids enjoy

5th grade Special Ed teacher: students work diligently and gain understanding of concept. Becomes increasingly challenging as they advance. The timer is a deterrent to my more nervous students, making this too stressful for some to benefit from. Also, starting over invests too much time in easiest level for those who can't pick up speed for physical or neurological reasons. I recommend both Pearl Diver and Lobster Diver.
