The deposit behind the headline
Spinfin pairs a recorded 350% bonus up to A$10,000 with 500 free spins. Its distinguishing feature is the gap between a generous percentage and the substantial deposit needed to approach that ceiling.
If 350% applied uniformly to eligible deposits, reaching A$10,000 in bonus credit would require roughly A$2,857. That illustration explains the scale; it does not establish that the promotion uses one deposit or a single rate.
Five hundred spins are a separate calculation
The spin count cannot simply be added to the cash figure. Five hundred spins at different stakes would produce very different nominal packages, even before game restrictions and treatment of winnings enter the comparison.
For this package, the useful questions concern allocation: whether spins arrive together or in instalments, which games receive them, and whether their winnings create another wagering balance alongside the deposit bonus.
Evidence and editorial boundaries
Editorial analysis of supplied promotional claims, not a customer test. No account was opened, money deposited, games played or withdrawals measured. Offer currency and availability were not independently confirmed. The regulator source explains Australian rules; it does not verify this brand.
