Today's switchboard
โ
can you switch them all off?
โ 1Switchly is a free daily lights-off logic puzzle. Everyone gets the same board of lights each day, with some of them switched on. Your job is to switch every light off in as few taps as you can.
Tapping a light flips it, and also flips the lights directly above, below, left and right of it. Lights that were on go off, and lights that were off come on. Tapping the same light twice puts everything back, so the order of your taps doesn't matter, only which lights you tap. Each day has a par: the fewest taps that can possibly switch the board off, worked out exactly by a solver. Undo takes back your last tap for free, and Restart puts the board back to the start without costing anything. The board is 5ร5 with a par of 4 to 6 from Monday to Thursday, and 6ร6 with a par of 7 to 9 from Friday to Sunday.
Switch everything off in par and you earn 12 points. Any tap that isn't needed has to be cancelled by tapping the same light again, so extra taps always come in pairs: finishing two over par earns 10, four over earns 8, then 6, 4 and 2 at ten over. Once you're past ten over par without finishing, the day is over, and you'll get a warning before your last move. Stuck? The helper lights up one tap from a shortest solution from wherever you are, but it halves the day's score and is only available until you're three taps over par.
Your play streak counts the days in a row you've played, and your solved streak counts the days in a row you've solved the puzzle. Play seven days running and you earn a 7-point bonus, or 14 points if you solved all seven. Miss a day and the streaks start again. A new puzzle arrives every day at midnight UTC.
