5Quick answer
Level 21 uses a support arches made from Stone, Wood. Its 8 targets reward a low opening shot and patience between impacts.
Shot-by-shot plan
- Use shot one on the lowest stone element nearest the shared center.
- Remove the lowest shared support and wait for gravity before cleaning up. Watch all 8 targets before firing again.
- Keep the final 4 reserve shots for anything left near an edge.
Why this works
The support arches concentrates weight through a small number of contact points. Removing the stone path transfers that weight sideways, so gravity does more work than a direct hit on every target.
Common mistakes
- Firing again while the support arches is still moving wastes the 9-ball budget.
- Aiming high can leave a stable base and force an avoidable cleanup shot.
