🎮 About Waterpark Tycoon
Waterpark Tycoon is a Roblox tycoon where you build out a waterpark across themed slide and pool sections, stack Cash income from visitor entries, and unlock harder-to-build attractions across gated upgrade steps.
explosion! drops a 2x Cash Boost (30 minutes) and grandopening! drops a 2x Cash Boost (30 minutes) as the two active drops in the panel right now.
Cash Boosts double your park income during the boost window, so stacking both codes back-to-back gives you a full hour of doubled Cash to fund a big slide or pool expansion.
