DropLab is a match 3 puzzle game. Drop bugs on the grid to create rows and columns of 3 or more bugs with matching colours. These will be vaporised and the bug juice will fill the test tubes at the bottom of the screen. Click and hold the left mouse button anywhere on the grid to begin dropping and then drag to drop four or more bugs. Release the mouse button to drop the bugs onto the grid where they will follow the arrows. Match rows or columns of the same colour to remove them from the grid and fill the test tubes. Fill all the test tubes to complete each level.
