How to play Star Battle

Bring your attention to one round of Star Battle. Place one star in each row, column and region, with no touching stars even diagonally. Look at what changes after your first action. Read the objective before making your first input. Use the example below to understand a decision.

Solve ten 6×6 puzzles with one star in every row, column and region. These boards use the one-star rule.

Review a difficult moment

When a decision goes wrong, compare it with the common mistake described below. Start again only when you intend to leave the current round. Use the example to check your reasoning.

Your goal

Place one star in each row, column and region, with no touching stars even diagonally. An attractive position is not enough unless the goal is met. Check the rules when you are unsure.

Step by step

1. Tap to place a star, mark a cell or clear it.
2. Respect fixed starter stars.
3. Check rows, columns and coloured regions.
4. Check puzzle verifies the final arrangement.

Controls

Click or tap squares or graph edges. Number boards include a digit pad. Undo reverses the previous change; Check puzzle validates the solution. Use the control method described here for this activity. Avoid pressing the same control repeatedly while a move is being processed.

A useful example

A placed star rules out all eight neighbouring squares. Focus on why the action is allowed, not only its outcome. Keep the controls nearby.

Watch out for this

Different rows do not make diagonal neighbours legal. Compare the situation with the worked example. When a decision goes wrong, compare it with the common mistake described below. Start again only when you intend to leave the current round.
