Common Questions

Tower Defense Simulator FAQ

Is Tower Defense Simulator free to play?

Yes. Tower Defense Simulator is a free Roblox experience developed by Paradoxum Games. Optional Robux gamepasses and bundles speed up progression, but they are not required to play or to clear the standard modes.

What is the latest Tower Defense Simulator code?

The most recent code listed on the official Roblox page is 2MILLION, which grants the Mercenary Pursuit skin. Redemption availability is confirmed in game, so check the codes page before your next match.

Can you play Tower Defense Simulator with 5 players?

Standard matchmaking runs up to four players, while the lobby party system allows a group of six. A five-player party has to split into smaller squads to enter a standard elevator.

Which Tower Defense Simulator mode is the hardest?

Hardcore, Voidcore and the toughest Insane maps are the most demanding content. Hardcore changes early income and adds Blighted enemies, so it depends on a coordinated loadout rather than raw tower levels.

How do you get gems in Tower Defense Simulator?

Gems come from specific modes, events and challenges rather than ordinary coin farming. The gem farming pages cover the current routes and the towers those routes require.
