Stop me if you've heard this one before. TileDrop is a game in which you need to form lines by rotating and positioning differently-shaped blocks that fall from the sky.
OK, yes, TileDrop does sound a little like Tetris. In fact, it's so much like Tetris that you could say the developer of this game has had an imagination bypass. The pieces are the same shape, the scoring system is the same, the layout of the board is the same, etc.
Of course, this isn't necessarily a bad thing, because Tetris is one of the greatest - if not the greatest - handheld game every created. As soon as you pick up and play TileDrop you'll be reminded of the impossibly addictive gameplay of its distant ancestor. Playing is so easy too. You just need to use the directional buttons or the number pad to spin the pieces or speed up the falling process. There is a high scores board that keeps track of your top score, so there's always something to aim for.
If you're a fan of Tetris, you'll love TileDrop. Just don't expect any originality.
