How to play
Close every word circuit
Every side is a word. Read it in the direction of its arrow: the bright corners supply its first and last letters, and the empty circles in between need letters from the charge bank.
Drag a letter into an empty node, or tap a letter and then its destination. A completed word seals its rail with power. There is no timer and no penalty for trying a different arrangement.
Use Spark whenever you want a nudge. It highlights one candidate letter and its destination, without placing it for you.
One expanding circuit
From a square to a dodecagon
Each Circuit contains nine linked shapes: 4-gon, 5-gon, and onward until the final 12-gon. Finishing one shape reforms the board for the next, so the puzzle grows in both size and rhythm as your circuit charges.
Letters can repeat across different words, but each individual charge-bank tile has one exact place. The shared corner letters turn every correctly sealed side into the start of the next one.

Common questions
FAQ
Which direction does a side read?
Follow its arrow. Each word starts at one bright corner and ends at the next, even if that means reading right-to-left or upward on the page.
Can I move a letter after placing it?
Yes. Until its word seals, move a tile to another empty circle or return it to the charge bank. Sealed rails stay locked because they are already correct.
What does Spark reveal?
Spark pairs a candidate letter with the node where it belongs. It is a visual clue, not an automatic solve, and you may use it as often as you like.
