How to play Boltborne
1. Find the first release
Only empty holes uncovered by every remaining plate can receive a screw. The round parking hole below the board starts open. A screw still holding any plate can be selected.
2. Move, then release
Choose a screw and a clear destination hole. The screw stays in that destination for the rest of the attempt. Every plate with no screws left falls away, revealing its holes. Plates can share a screw hole.
3. Leave enough space
Removing part of a plate can fill your available holes before that plate releases. If no legal transfer remains, the workshop is blocked. Undo a move or restart. You win only when all plates are released.
Controls and progress
Tap holes, or use arrow keys to focus a hole and Enter or Space to select it. U undoes and H shows a verified next transfer. Hints mark a source and destination; they do not play the move. Each of the 12 workshops keeps its own progress in this browser.
