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.
There is a key for every action that is defined above. These key binds can be viewed and edited in the Settings.
When you play, your side looks like this.
When you try to move left, right or down, and hold the key, your block first moves by one line or one column, then after some amount of time the block starts moving at a higher rate. Theses rate are defined by the Delay and Repeat values. As for the key binds, you may customise them in the Settings. Values have to be filled in milliseconds.
Note that, putting lower delay and repeat rates may help you play faster, but putting too low values may result in losing control and misdropping your blocks (this is usually annoying).
Handicap types are made to make your survival harder. In Multiplayer and Ghostbuster modes, handicap lines are sent when your opponent makes specific line clears. In Survivor and Elite Survivor modes, handicap lines appear at regular time intervals.
There are three handicap types, but according to what you are playing you might or might not change the current handicap type. In Survivor and Elite Survivor modes, the handicap type is always handicap with holes. In Ghostbuster mode, the handicap type is either solid handicap or handicap with bombs. In Quickplay mode, the handicap type is always handicap with holes. In Custom rooms, the handicap type can be anything, and it is determined by the room creator.
In games modes else than Survivor and Elite Survivor, incoming lines are visible on the bar which is located on the grid's right. Handicap lines only appear after the next block has been placed. If you clear lines while you had incoming lines, the handicap lines do not appear, and according to the number of lines you should have sent to the opponent, part of them are removed. The remaining ones might still appear after you place the next block, if you don't clear any line at that time.
When you top out for any reason, all the handicap lines on your side are removed.
Solid handicap basically consist of filled lines. Since it is not possible to clear them in the normal way, in order to get rid of them one has to clear lines on their side. Then, while that player was handicap lines at the bottom of the grid, lines that should be sent to the opponent are not sent and are replaced by handicap line removals.
Handicap with holes are lines with 9 slots out of 10 that are occupied. Such lines are cleared in the same was as usual lines are. The hole's positions are determined randomly. However, when several lines are sent by placing one block, all these lines have their hole at the same position.
Handicap with holes are filled lines, but one of the 10 slots contains a bomb. Such lines are cleared by placing a block right above the bomb's position. The hole's positions are determined randomly. However, when several lines are sent by placing one block, all these lines have their hole at a different position.
The number of lines that are sent is computed as follows. Note that scores below are cumulative.
|Combo count||Lines sent|
|B2B T-Spin Mini||1|
|B2B T-Spin Single||1|
|B2B T-Spin Double||2|
|B2B T-Spin Triple||3|
The anti-stalling system is made to avoid people not play in order to not being KO'ed.
