Read a demolition attempt against its allowance.
Check the remaining supply
Knock Balls PRO describes throwing balls at structures, a limit on the allowed throws and a claim that saved balls count double at the next level. Read the actual allowance and objective before taking a shot. A dramatic collapse is useful only if it satisfies the current task within the rule the game presents. The source does not document a particular structure layout or scoring formula.
Observe what one impact changes
After a throw, inspect which parts of the structure moved and what remains. Use that feedback before repeating an identical action automatically. A visually central block is not guaranteed to be a weak point, and an unusual shape does not prove a specific physics interaction. The mouse-and-touch field does not supply a full aiming guide, so follow the actual prompt.
Verify the carryover claim
If you finish with balls unused, read the transition and next-level display to understand how the game applies the advertised benefit. Do not assume it means a universal bonus multiplier or permanent stock. This article offers no tested demolition sequence or guaranteed way to save every throw. It keeps the present allowance and the claimed future effect separate, so a deliberate shot can be evaluated from both the visible remaining structure and the resources actually recorded.
