Follow the steps for Chess Online
Take a moment with Chess Online before moving to another game. Checkmate the opposing king. Keep the game area visible while you use its controls. Begin with the local / basic computer mode shown on the page. Choose a clear next step rather than rushing through the instructions.
Play on one device with a friend or against the basic computer opponent. Repetition and the fifty-move rule trigger an automatic draw here; there is no internet matchmaking or tournament clock.

See the idea in action
Castling cannot pass through an attacked square. Apply the same reasoning to the position in your own round. Verify the rule before continuing.
Keep this in mind
The computer is a small search opponent, not a rated engine. A different version of the game may use a different rule. After a move, check what changed. Decide which rule explains the new state before acting again.
