Spark Grid: Neon Circuits

Rotate tiles, light every bulb, and keep red and blue from touching. A fresh neon puzzle every day, 150 levels to master, and no ads. Can you solve it under par?

Rotate. Connect. Light it up.

Spark Grid is a glowing neon logic puzzle. Tap tiles to rotate the pipes, send power from the source to every bulb, and watch the whole circuit come alive. Easy to learn in seconds, deeply satisfying to master.

A NEW PUZZLE EVERY DAY Every day brings a fresh Daily Circuit, the same puzzle for every player. It starts gentle on Monday and gets tougher through the week, with Sunday as the ultimate challenge. Solve it every day to build your streak, and compare your time on the Game Center leaderboard.

150 LEVELS TO MASTER Work your way through 150 levels that slowly introduce new ideas:

• Locked tiles that can't be rotated. Use them as clues.
• Two-colour circuits. Red bulbs need red power, blue bulbs need blue.
• Short circuits. If red and blue touch, both go dark, so keep them apart!
• Bridges that let red and blue cross without touching.

PLAY SMART, EARN STARS Every puzzle has a par. Solve it in par moves or fewer to earn all three stars. Stuck? Use a hint to fix one tile, or undo and reset as often as you like.
