A unique game concept that combines shooting with logic puzzles. There are three game modes, all of which involve shooting balls or other shapes at a rotating circle of shapes by using the arrow keys to fire up, down left or right.  The game modes are:

Match It: complete patterns by firing matching elements into empty spots in the circle.

Clear it: A match 3 game where you fire objects to  create and clear groups of three matching objects

Shoot Out: Clear the circle by hitting objects with like objects

The games work will all screen sizes and have working sound. There are  a total of 100 levels in the 3 games.

Keys: The OK button doesn't work, use the Call key as OK.

Similar to the old Frogger game, the object of Why Chicken Why is to get your chickens across a busy four lane highway without getting run over.  The chickens are slow, the cars and trucks are fast and you only have a limited amount of time so this game is harder than it looks. Sound works, keys are mapped correctly (except the OK key, use the Call key) and the game works with all screen sizes.

Thanks to Chevan for discovering this street racing game. Race the streets of Las Vegas, San Francisco, Miami or New York with a choice or four hot cars. This is the 128x128 px version, ideal for the Boost phones with square screens like the i290 and i335. It's OK on the i176 and i465 too although it does quite fill the screen.
