Controls
Use the on-screen controls with a mouse or touch. A careful first action helps you become familiar with the layout. Avoid pressing the same control repeatedly while a move is being processed.
Work through an example
Tapping the centre changes five cells. Tapping a corner changes three. Diagonal neighbours are not affected. Apply the same reasoning to the position in your own round. Notice the change in the playing area.
Check this before moving on
An unlit tile can still be tapped; it may be necessary to solve the board. Read the feedback to see why an action did not have the expected result. Read one step at a time and try it on the playing area. Match the instruction to the control you use.
