How to play Star Battle

Try Star Battle at your own pace and keep its objective in view. Place one star in each row, column and region, with no touching stars even diagonally. Use the example below to understand a decision. Begin with the solo mode shown on the page. Look at what changes after your first action.

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

A careful first round

Before your first action, say what you are trying to achieve. Then compare the result with the goal. Refer to the controls when needed.

Your goal

Place one star in each row, column and region, with no touching stars even diagonally. Keep that objective in view throughout the round. Return to the instructions when a step is unclear.

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. Make sure you are interacting with the game rather than the surrounding page.

A useful example

A placed star rules out all eight neighbouring squares. Apply the same reasoning to the position in your own round. Consider the next action carefully.

Watch out for this

Different rows do not make diagonal neighbours legal. Read the feedback to see why an action did not have the expected result. Watch the feedback after an action. A message can explain whether the input was accepted or whether a rule needs attention.
