Friend boost
+5% Power per friend
A simple estimate is Base Power × (1 + 0.05 × friends). Treat it as an estimate until the result matches the current in-game counter.
Kick Ball to Space Friend and Premium Boosts
The creator description states +5% Power per friend and +10% Power for Premium. It does not publish a friend cap, stacking order, rounding rule, or Premium price on the game page.
Premium boost
+10% Power
A separate estimate is Base Power × 1.10. Do not claim the friend and Premium effects multiply or add together until the UI proves the order.

Server updates, caps, and rounding can make the visible result differ from a simple formula.
