Drag is an easy to understand, yet hard to master puzzle game for iOS and Android devices. The game is about trying to select the marked fields using the commands:
Every level has a unique set order and amount of commands which must be used in given order. When you drag a square using your mouse on a computer, you make a selection. With your finger on your device, this is exactly what you need to do. You can undo a performed command using the half arrow button underneath the provided commands.
If a level seems to hard, hints can help you out or you can skip and save the level for another time, sometimes the right idea will come to mind later!
