Kill The Lights!

Kill The Lights! is a puzzle game in which you toggle blocks in patterns to turn off all the lights. Clicking a block changes its state and the states of other blocks around it, according to the selected pattern. In Normal mode, you solve the puzzle without interruptions; in Arcade mode, a computer opponent turns blocks on while you try to turn them off.

Shapes and game types

The puzzles use four shapes: Plus, X, Plus Across The Board and X Across The Board. You can play them in either of two game types:

• Normal: turn off all the lights without interruptions.
• Arcade: face a computer that uses bombs in different shapes to hinder your progress.

Arcade challenge

Arcade mode has six difficulty levels, from Very Easy to Literally Impossible. You can use three special moves, which you purchase with moves earned during play. You can accumulate up to 25 moves to spend on them:

• Turn Off Row: turns off every block in one row.
• Turn Off Column: turns off every block in one column.
• Toggle 1: toggles one block on or off.
