Christmas Lights

Rotate the Wires and Light Up the Whole Christmas Tree!

Someone tangled up the Christmas lights again — and it's your job to fix them! Christmas Lights is a cozy holiday puzzle where the power comes from a lightning bolt at the bottom of the screen, and a string of scrambled wire pieces stands between it and the bulbs. Click or tap any piece to rotate it. Turn the right pieces the right way, and electricity flows step by step through the circuit until every single light glows. When the whole board sparkles, you've won!

The rules take about ten seconds to learn, but the puzzles get delightfully tricky. Every wire piece is a small section of the circuit — a straight bit, a corner, a junction — and each one can face several directions. One wrong turn and a whole branch of lights stays dark. The fun is in tracing the flow: where does the power enter this piece, and where does it need to go next? It's the same kind of logical thinking engineers use, wrapped in twinkling holiday colors.

Here's what makes it exciting: the clock is ticking. Your solving time is recorded from the moment you start, and when the last bulb lights up you can submit your score to the online leaderboard. Fast fingers and a clear head can push you up the rankings against other players — so once you've solved a board, try again and see how many seconds you can shave off.

Christmas Lights is a great pick for kids who enjoy brain teasers, and it quietly sharpens useful skills: spatial reasoning, planning ahead, and working carefully under time pressure. It's calm enough for a quiet December afternoon but competitive enough for a family speed-run contest. Who in your house can light the tree fastest?

If circuit-style puzzles are your thing, there's plenty more to untangle in our collection of puzzle games — or chase another leaderboard in Block Drop. The game is free, runs right in your browser, and works on computers, tablets, and phones. The lights are waiting... time to bring back the holiday glow!
