I never played the original Biniax game, so Bixi is based on the following text that I saw on Wikipedia:

---
The gaming field is 5x7 pairs of elements. Every pair consists of two elements out of four possible types (colors).
Player is a single element, who can move on empty fields or can take a pair, if the player's element is present in the pair. If a pair is taken, the player's element is swapped to the other element of the pair. 
The field is scrolling down on time event or after certain moves are spend (depending on the game mode). Game over is when there is no move for the player.

The following are my own additions to the game, to make it more fun (?):
1. There are special items that you can collect for cash.
2. When you have enough money, a randomly selected "power" is added to your list.
3. Press "fire to use a power, which depending on the type can be used to clear the board, change player color, etc.
4. If you drop a brick (i.e. the last row contains a brick when it "falls"), all your money is lost.
