Shock Panel

Shock Panel is a type of panel that appears in the puzzle game Tetris Attack. Their appearance is gray with a white exclamation mark.

This type of panel is rarer than the regular panels. When a player matches three of these in a line, they send a Shock Block to their opponent which makes any Garbage Blocks on top of it unbreakable. Players can also match more than three of these at a time. If they match four of these, they send two Shock Blocks, and if they match five, they send three. They only appear in VS modes.
