Strategy

Start by spotting the highest values. Those are your priority targets. Connect them to the smallest neighbors first – the drop‑off is biggest that way. Keep an eye on parity; odd numbers need an even partner to disappear cleanly. When you hit a dead end, backtrack and try a different link direction. Each level adds new node layouts, so adapt your pattern‑recognition on the fly. Master the rhythm, and the puzzles melt away.
