Electrical crossword

How to play

Use the numbered Across and Down clues to fill the white squares. Each answer is one word. Shared squares belong to both answers, and black squares separate the words.

Tap a square to select its word; tap the same square again to switch between Across and Down at a crossing. Tap a clue to jump to its first square. Type letters on your phone keyboard or computer, use Backspace to erase, and use arrow keys to move on a computer.

Check word checks the selected answer; Check puzzle checks every square. Squares that need another look are highlighted. Reveal fills every answer and shows the answers list. The timer starts with your first letter and stops when every answer matches. Share your result when you finish.

About Electrical

Circuit, current and safety words from electrician basics.

Every layout is generated and checked by code. Clues are question stems from the verified bank, and answers are single words from the correct options. A checker reads every Across and Down run from the finished grid, checks its answer and confirms that all the words connect. A topic page and seed always give the same puzzle; New puzzle changes the seed. The daily mini changes at midnight UTC.

Tips

Start with a clue you know, then use its crossing letters to narrow the other answers. The number in brackets tells you how many letters to enter.

A criss-cross layout has black squares around the interlocking words. Work through both clue lists, and use the highlighted clue above the board to keep your place on a phone.
