About this game
Without a timer. No rush. Just you and the grid.
How to play
The number on the node is how many pulses it still needs to receive. Clicking on a node sends an impulse to all neighbors above, below, left and right.
The node itself does not change from its click. The node that has received everything you need indicates that it is ready. It is also possible and often necessary to click on a ready-made node with ✓: it does not change from its click and remains ready, and distributes an impulse to its neighbors as usual. It's not the click itself that's dangerous, but the click from a neighbor that will burn out from an extra impulse.
If the node gets an extra boost, it will burn out and show ✕.
On a light profile, the first burnout is forgiven, then not.
The goal is to bring all the nodes of the field to readiness. The order of clicks is not important: it only matters how many pulses each node has received.
