What This Game Is
Flip is a self-contained logic puzzle built around one clear objective. Each new board gives you a fresh problem to solve, so it works well for quick sessions and repeated play.
Flip groups of squares to light them all up at once.
How to Play
This game can be played with either the keyboard or the mouse. Left-click in a square to flip it and its associated squares, or use the cursor keys to choose a square and the space bar or Enter key to flip.
Most puzzles in this collection reward deduction more than speed. Focus on the most limited choices first, use the clues to narrow the board, and avoid guesses unless the puzzle mode clearly expects them.
Beginner Tips
- Start with the area that has the strongest clue or the fewest legal options.
- Use marks, notes, or temporary indicators if the puzzle supports them.
- Try to preserve flexibility instead of committing too early when multiple moves look possible.
- If the board gets messy, restart a fresh puzzle and apply what you learned from the first run.
