Tetrinet is a multiplayer tetris variant. On this tetris variant,
two players must compete, trying not only to clear lines, but at the same time,
attack the opponent with Block Powers! Just don't say I didn't warn
you: this game is extremely addictive.
This incarnation of Tetrinet is programmed for the MSX platform,
and the complete game, including graphics and music, has only 4kb!
How to Load
This game is meant to be run from the MSX BASIC environment. Insert the disk
containing TETRINET.BIN in your drive, and then type:
If you're using an emulator, you will need to create a disk image before
playing. The recommended emulator for MSX beginners is
BlueMSX. To play Tetrinet in this emulator,
first you need to create a Windows Folder containing only the TETRINET.BIN file.
Then start BlueMSX and press Right ALT+F9. This will open the "Insert Directory"
menu. Select the folder where you placed the TETRINET.BIN file and start emulation.
After this, just type the BLOAD command above.
The game screen
Before you start to play, familiarize yourself with the game screen:
Two players play at the same time, player 1 controls the right field, player 2
controls the left field. Right below the playfield you can see the Block Powers
each player has stored. On this example, player 1 has the R power, and player 2
has no block powers available.
In the center of the screen, each player has a NEXT field, displaying what
will be the next block. Right below the NEXT field, each player has a log space,
each time a block power is used on the player, the name of the power will
be displayed there.
The game can be played with keyboard or joystick:
|Player 1||Player 2|
|Move block left||Cursor left||Joy 1 left
||A||Joy 2 left|
|Move block right||Cursor right||Joy 1 right
||D||Joy 2 right|
|Move block down||Cursor down||Joy 1 down
||S||Joy 2 down|
|Rotate block||Cursor up||Joy 1 up
||W||Joy 2 up|
|Drop block down||Spacebar||Joy 1, Button A
||Caps Lock||Joy 2, Button A|
|Power Select||M||Joy 1, Button B
||Tab||Joy 2, Button B|
When there is a Block Power available, you have three possible commands:
- Use the power on yourself: Press the Power Select button,
and while keeping it pressed, press the down button.
- Use the power on your opponent: Press the Power Select button,
and while keeping it pressed, press the up button.
- Discard the power: Press the Power Select button,
and while keeping it pressed, press the drop button.
If you want to abort the game, just press CONTROL+STOP. Pressing CONTROL+STOP
while in the intro screen returns you to the MSX BASIC environment.
Just like in the original tetris, you can pile up your blocks,
and if one or more lines are filled, they will be removed from
your playfield. Try to remove more than one line at a time,
since this will send lines to your opponent!
- Clearing two lines from your field: adds one line to your opponent
- Clearing three lines from your field: adds two lines to your opponent
- Clearing four lines from your field: adds four lines to your opponent!!
Also, for every line you remove from your playfield, one of your blocks will turn
into a Special Block. These blocks are white and have a letter inside. If you
manage to clear a line containing a Special Block, it will be added to your
Block Powers collection, just below the playfield.
You can use these Block Powers on yourself or in your opponent. Each
Block Power has a different effect:
- A: This is the Add Line block. It will add
a "junk line" to the player's field that
- C: This is the Clear Line block. It clears
the line closer to the bottom in the
- N: This is the Nuke block. This removes all blocks from a
playfield, giving the player a "fresh start".
- R: This is the Remove block. It removes 10 random blocks from
a player's field.
- S: This is the Switch block. This switches your playfield with
your opponent. If either of
the fields' block stack is over 16 blocks
high, the stack will be lowered.
- B: This is the Basic block. It removes all Special Blocks from
a player's field.
- G: This is the Gravity block. It takes all the blocks
on the field and "pulls" them all towards
the bottom of the field, eliminating any
gaps in the blockstack.
- Q: This is the Quake block. This causes each of the lines of blocks
on a player's field to randomly shift left
or right or not at all.
- O: This is the Bomb block. This is the block bomb, when used on a
player, it clears 3x3 portions on their
field anywhere there are 'o' blocks.
Any blocks that were in the 3x3 areas
are scattered around the field.
Use your imagination and extract the most of the Block Powers!
- Add Line is usually sent to your opponent, to make his field higher.
However, you can use it on yourself, in the beginning of the game, to collect
Special Blocks faster!
- Clear Line can be used like this, too: when your opponent is about
to get a Special Block, clean his line!
- If you see your oponent is about to Switch fields, mess up
your own blocks using Remove or Quake, so he will get a
- If your opponent is about to send a Bomb to you, you can
use Basic on yourself and remove the threat!
There are many possibilities, you can think up a new strategy for yourself!
This game was programmed by Ricardo Bittencourt. The main music was
designed by Alex Sato. The original version of Tetrinet was created
by St0rmCat. This manual was revised by Cyberknight and
This game requires an MSX compatible computer with 16kb of RAM. The game
adapts itself for 50Hz or 60Hz, so the music will be always played at the
same speed. Special care was taken to preserve the BASIC environment,
so you can return to BASIC after playing, without even losing the program
you were working on. This game was programmed in Assembly, and portions of
it have been superoptimized.
No penguins were harmed during the making of this game. Enjoy Tetrinet and have fun!
