Node Cycle Puzzle

Find the pattern. Clear the circuit. In Node Cycle Puzzle, every move changes three connected nodes, and every board has a logical solution. HOW IT WORKS Each node has three states: OFF, ONE and TWO. Tapping a node changes that node, its neighbor to the right and the one below it. Each affected node cycles OFF → ONE → TWO → OFF. At an edge, only existing neighbors change. Your goal is to leave every node OFF. A SIMPLE SOLVING METHOD Start in the top-left corner and look at that node's current state. If it is OFF, move on. If it is ONE, tap it twice to cycle through TWO to OFF. If it is TWO, tap it once to reach OFF. Then move to the right and repeat. When you finish a row, start at the left of the next row. Keep going until you clear the bottom row. Each move may change nodes to the right or below, so judge a node when you get to it. Nodes you already cleared stay OFF. For example, imagine these three rows: ONE OFF TWO / ONE ONE TWO / OFF TWO OFF. Tap the top-left twice, the top-middle once, and then the center once. All nine nodes turn OFF. The in-game How to Play guide shows the starting board and walks through these moves.
