Time Ball to keep you mesmerized

In the world of handheld consoles that offer far more interactive games than those classic Nintendo Game-n-Watch devices a couple of decades ago, are there any gaming devices out there that can still surpass a video game in terms of keeping the player engrossed? The Time Ball certainly tries and succeeds if but for a while, before the large library of the Nintendo DS Lite crushes it. This electronic game requires you to hit the highest score in half a minute or a full minute as you attempt to make the ball roll over the pluses & minuses that will inadvertently affect your final score. It sounds pretty simple in theory, but the manufacturer has thrown in sound and lights that go faster in order to increase tension in the air. I wonder if a random shaking of the £24.99 Time Ball will be able to net me a high score.
