Game, Nintaii for BlackBerry
If you have never heard of Nintaii before here is a brief review from Blackberrysync.com:
Nintaii is a brain twisting puzzle game of rolling blocks and switches. Be ready to roll your block over the course of this 100 level challenge. Just like most of the greatest puzzle games, Nintaii has a simple concept and yet proves to be very challenging, electrifying and attractive!
The Japanese kanji ?nintai? means patience, perseverance, or endurance
The objective of the game is to tumble a rectangular block through each stage and deposit it into the square hole at the end. Switches, road blocks and arrows are located in many levels. Switches are activated by having the block stand on it.
You can use touch, accelerometer, or the trackball (on other models running 4.7 to move the block around.)
It looks very cool to me but it's $9.99...If it's something you think your interested in you can find the download and a video showing how to use it here.
