4. The Game

The objective of the game is, like other tetris clones, to manipulate falling code blocks to form horizontal rows of blocks. When horizontal rows of blocks are formed they will disappear to solve the access codes.

The gameplay screen is basically divided into three parts:


The level being played and the codes solved are shown on the left side. The playfield limited by laser lines is on the middle. Game time, next code block, score and activated bonuses are displayed on the right.

The falling block can be moved to left and right by the left and right arrow keys. It can be rotated by pressing the up arrow key and falling speed can be increased by the down arrow key. Left-handed players can also use the A, D, W and S keys.

* The game can be paused using the P key.
* Keyboard sensivity can be set using the plus and minus keys on the numpad.
* In game music can be turned on and off using the M key.
* The Esc key ends the game.
* F12 key can be used to exit the game and return to Windows immediately. Your game will NOT be saved when you use this key.

You can get points when you:
1. Press the down arrow or S key to increase the speed of the falling block,
2. Clear one or more lines.

Fast Code Bonus: If you play the game fast enough by increasing the speed of the falling block, fast code bonus will be acitivated and the points you get when you increase the speed of the falling block will be doubled as long as this bonus is active.

Optimised Code Bonus: When you clear four lines simultaneously, optimised code bonus will be activated. It will remain active for a while and the points you get when you clear the lines will be doubled.

Clean Code Bonus: This is a bonus very hard to activate. When you clear all the playfield this bonus will be acitvated and all points you get will be multiplied by 4. This bonus will remain active until the level ends.
