TOFTI Star Circuit

TOFTI Star Circuit is an original logic game about repairing a network of light in a dark sky. Each square contains an energy path pointing in one or more directions. Tapping a square turns that piece clockwise. The level is complete when energy from the yellow source star reaches every piece and the whole sky lights up. The rule takes one tap to learn, while the larger boards ask you to think several turns ahead and keep track of more than one branch at once.

The journey contains twenty levels. The first four use a 4 × 4 board to introduce corners, straight paths and terminal stars. Later 5 × 5 and 6 × 6 networks add longer branches and closed loops. The final four levels expand to 7 × 7 and require several areas to be read together. Every level is available from the beginning; no advertisement, account or payment is needed to continue. Each puzzle begins as a connected target network, then its pieces are rotated independently to make a guaranteed solvable arrangement.

A link works only when the ends of two neighboring pieces face each other. Pieces supplied by the source glow turquoise and yellow, while parts still waiting for energy remain muted. This makes it possible to read both the shape of an individual tile and the part of the network that is actually working. Hint turns one incorrect piece to its target direction, and Undo restores the state before the last turn or hint. The theoretical shortest turn count appears on screen; finishing close to it and using fewer hints earns a better star result. There is no timer, life system or in-game purchase.

The interface rearranges itself for phones, tablets and computers. Play with simple taps, a mouse, or arrow keys and Enter. H, U and N are shortcuts for Hint, Undo and Refresh. Best star results, sound preference and the most recently selected level remain only in this browser when local storage is available. The game code, circuit illustrations, cover artwork and short synthesized sounds were created for TOFTI. The package has no outside game provider, advertising SDK or externally loaded runtime files.

How to play

The yellow star is the energy source. Tap a circuit square to turn that piece one quarter-turn clockwise. Make the ends of neighboring paths face each other, then connect every square into one light network beginning at the source. The level ends when every piece is supplied and no energy end is left open.

Glowing turquoise paths are connected to the source; muted paths are not connected yet. Shortest is the theoretical minimum number of taps needed to turn all pieces to their target directions. Hint corrects one wrong piece. Finish without hints and close to the shortest count to earn three stars. Undo restores the previous action, while Refresh returns the current level to its original scrambled arrangement.

Choose any of the twenty skies from Levels. On a keyboard, move with the arrow keys and turn the selected square with Enter or Space. H gives a hint, U undoes and N refreshes. The sound button mutes the synthesized effects. Reloading restarts the open puzzle; your best star results remain in this browser.
