Plan backward from the core
The final peg must sit on the gold core, not merely anywhere on the board. Preserve a route that lets the last outside peg jump into it.
AYE.GG / PEG-STRATEGY PUZZLE
Peg Reactor
Jump over pegs. Clear the chamber. Land the final piece on the core.

Remove every peg except the one on the core.
Choose a peg, then a glowing empty socket two spaces away. The jumped peg disappears. Jumps are orthogonal only; U undoes and Escape clears a selection.
Campaign progress stays on this device.
How to solve Peg Reactor
Avoid isolated pegs
A peg with no neighbor cannot move. Before taking an attractive jump, check that the landing pattern still gives every remaining cluster a way to reconnect.
Fifty escalating chambers
Early 5 × 5 boards teach clean chains. The campaign grows through 6 × 6 and 7 × 7 chambers with up to 29 pegs. Every level is generated from a complete reverse solution, so it can be cleared without guessing.
