Energy Coin

A small spark. A bright idea. Welcome to Energy Coin, a colorful logic puzzle where every pulse changes the network. Your goal is simple: make every node glow. Finding the right sequence is where the discovery begins. THREE SIGNALS TO EXPLORE Each type of node sends a different pulse: • Green flips itself and its horizontal and vertical neighbors. • Blue flips itself and its diagonal neighbors. • Red flips every node in its row. A pulse switches glowing nodes off and dark nodes on. Watch how the signals interact, experiment with different combinations, and bring the whole circuit to life. LOOK BEFORE YOU PULSE Turn on Preview to see which nodes your selected signal will affect. Send the pulse when you are ready, undo a move, or ask for a helpful hint. DISCOVER TEN CIRCUITS Explore ten puzzle stages that introduce larger networks and different signal combinations. Revisit completed circuits to improve your best move counts. KEEP THE ENERGY FLOWING Try the daily frequency for a new starting arrangement each day, or visit the Workbench to experiment with fresh circuits beyond the main stages. PLAY AT YOUR OWN PACE • Preview each signal before making your move. • Use hints, undo, and restart whenever you need them. • Track completed circuits and your best results. • Resume an unfinished puzzle with saved progress. • Adjust tap sounds, touch feedback, and motion. • Play offline without an account. Choose a node, send a spark, and discover how one small change can light up the whole network.
