Prison Base Tycoon

Prison Base Tycoon is a competitive tycoon game by Fat Whale Games that combines passive base-building with active player-vs-player raiding in the same session. Players construct a prison facility to generate Cash, then arm themselves and attack rival bases sharing the same server. With over 172 million visits since its 2019 launch, it is one of the most enduring PvP tycoon titles on Roblox.

The session splits cleanly between two activities that feed each other:

• 🏠 Click tycoon nodes to build prison cells, guard posts, and administrative buildings that raise passive Cash income
• ⚔️ Spend accumulated Cash at the armory to buy weapons and raid other players' bases for more Cash
• 💰 Cash is the sole currency - no secondary currencies, no rebirth system, just a straight climb
• 🎭 Servers hold only 6 players, making combat encounters frequent rather than rare interruptions
• 💼 Joining the Fat Whale Games group grants a free weapon and extra movement speed - a real combat edge
• ⏳ Tycoon autosaves between sessions so all building progress carries forward

Economy is all Cash - earned passively from built structures and actively from successful raids. Group membership provides a free weapon and speed bonus that gives a meaningful advantage in early-game raids.
