Seven Circuit

Seven Circuit - a puzzle where segments of a decorated circuit lie across a square grid and every tap turns the selected segment ninety degrees. A red node sits on the left edge of the board and a green node on the right, and each level is finished when a continuous line of pipes runs from one node to the other. Straight pieces, elbows and three-way pieces are mixed with empty cells, and only the segments already joined to the red node stay lit, so the shape of the route is visible while it is being assembled. Every turn takes one move from the counter above the board, the level closes the moment the two nodes are linked, and the round is over as soon as the counter reaches zero with the line still broken. Points are added for each completed level and for the moves left over at that moment, so a shorter solution counts for more. The board grows every few levels, from a small grid up to seven cells per side, and the number of scattered pieces grows with it. A pause panel opens at any time during a level and holds resume, restart, exit to the menu and a hint that sets one segment of the route into its correct position for a few moves. When the moves are gone, a result panel shows the score of the round next to the best result kept on the device. The stats screen collects the number of rounds played, the levels completed, the best and the average score and the total time in the game, and all of it stays between launches. Settings hold a vibration toggle, a toggle for screen effects, three difficulty steps that change the starting board size and the move budget, and separate resets for the best result and for the whole progress. A short rules screen is reachable from the menu and describes the same flow in a few lines.
