Beebris

BEEBRIS

This is the standard game mode. Points are scored by making

complete horizontal lines of blocks in the Well. Greater scores

can be obtained by ‘Quick-Dropping’ the tetromino - the higher

 the Quick Drop, the higher the score.

Once 10 lines have been completed, the level will increase and

 the game will speed up noticeably. This will continue to a point

 where it reverts back to slower speeds. As you continue further

 into the higher levels, you will see the start position of the

tetromino becomes lower - the Well top has been lowered!

The game ends when a tetromino is placed in a position above

 the Well top.

BEEBRIS+

Gameplay is similar to the normal BEEBRIS mode but with the

addition of new polyominoes for extra difficulty. These new

shapes do not tessellate quite as easily as the regular

 tetrominoes. To offset this there is another special single-block

 - the Bomb! This block will complete the line of blocks it falls to

even if the line is not complete!

ARCADE

This is similar to regular Beebris mode with some additions -
there are now 4 level types:

Normal
As with the regular game of Beebris, the object is to make
10 lines to advance to the next level.

Progressive Advance
The same as a Normal level but occasionally the game will
move all blocks in the Well upwards and insert a random
line at the bottom.

Random Blocks
The same as a Normal level but occasionally the game will
insert a new block into the well at a random position.

Pre-Built Well
The same as a Normal level but the Well will contain a
pre-selected pattern of blocks to start the level off with.

ARCADE+

The same additions to Beebris+ apply here - new
polyominoes and the Bomb!
