How to play

If you are new to this website, this is a good place to start.


The basic principle of Worldwide Combos is that you need to fill the lines of the grid with blocks. Once a line is filled, is disappears, preventing you from topping out.

When you play, you use one block at a time. You can do the following moves with it.

  • Move the block left or right (with left and right arrow keys).
  • Move the block down quicker (with the down arrow key) or instantly (with the space bar).
  • Rotate the block clockwise (with the up arrow key), counterclockwise (with the x key), or 180° (with the c key).
  • Put a block aside, or "hold" it (with the Caps key). If you already used this since the begining of the game, then your current block is replaced that the one you were "holding", otherwise you get the next piece.

When you play, your side should look like this:

A nice screenshot should appear here.

  1. your country flag, your username and your rating (1000 if there is no rating);
  2. your field
  3. your current block, which is falling down every second;
  4. your current block's ghost, in order to help you see where it's going;
  5. the block you are currently holding (assuming you are holding one);
  6. the number of times your opponent was knocked out;
  7. the number of lines you sent;
  8. informations about what you did (see "Sending lines" below)
  9. your upcoming blocks (your next block is the one at the top, and so on);
  10. the remaining time.

Key binds

The key binds that were given above are actually the default key binds. It is possible to change these, in the Game Settings. You may access these settings from the Dashboard (bottom-right button).

Speed tunings

When you try to move to the left, right or bottom, and hold down the key, your block first moves one row or column, then after a while, the block starts moving at a higher rate. These are the Delay and Repeat rates. As for the key binds, you may customise them in the Game Settings. You are asked to enter the values in milliseconds.

Note that reducing delay and repetition rates can help you play faster, but setting values too low can lead to loss of control and a bad fall of your blocks (which is usually annoying).

Sending lines

The number of lines that are sent is computed as follows. Note that scores below are cumulative.

Basic line clears

NameLines sent

Please note, that clearing a single line does not send lines to the opponent.


NameLines sent
T-Spin Mini1
T-Spin Single2
T-Spin Double4
T-Spin Triple6

When you place a T-like block in a way such that three of the block's "corners" are already occupied by another block that was already there before, then you make a T-Spin. A T-Spin Mini is a T-Spin that doesn't clear any line.


Number of combosLines sent

A k-combo is made, when you clear lines with k+1 consecutive blocks. A 1-combo doesn't send lines.


NameLines sent
B2B T-Spin Mini1
B2B T-Spin Single1
B2B T-Spin Double2
B2B T-Spin Triple3
B2B Quadruple2

A Back-to-back is made, when two consecutive line clears are made in the same way, provided this way of clearing lines is one of the five ways that are listed above. Please note, that it is not necessary to make these two line clears with two consecutive blocks.

How to win

The winner of a game is be the player who was knocked out the less.

In case of a tie, the winner is the player who sent the most lines to his opponent.

If there is still a tie, then we consider the height of the highest block in each player's grid. The player who has the lowest such block wins.

If there is still a tie, then nobody wins.


As said before, there are two distinct rankings: the solo ranking and the multiplayer ranking. For both of them, you need a valid account to be in.

Both ratings are similar to an Elo rating. Yet, the outcome of the game is 1 or 0 if or only if you win or lose by a sufficient amount of KOs. The outcome will be at least 0.8 if you win by at least 1 KO, 0.7 if you win because of the number of sent lines, 0.6 if you win with the numbers of KOs and lines sent being equal.

Please note that, winning a match doesn't guarantee that your rating change will be positive.

There is also a ranking based on tournament results. You gain points according to your ranking on every tournament you take part in. These points fade one year after the tournament has ended.

Frequently Asked Questions

How can I change my key binds and my speed tunings?

In your dashboard, click on "Settings", which is the button on the bottom in the main menu.

In the ghostbuster mode, my opponent freezes and gets knocked out alone.

It happens sometimes, sorry for the inconvenience. Keep in mind that if you keep playing until the end, then you will win. ;-)

In the multiplayer mode, my opponent's grid does not display correctly.

This is a bug that has not been solved yet. However, scores and match results are updated correctly whatever you may see. Sorry for the inconvenience!
