Ragdoll Stack!

Ragdoll Stack! is a physics-based obby on Roblox by solo developer SammyBnuuy with a single clever hook: spawn ragdoll characters, stack them on top of each other, and use the combined height to leap over progressively taller walls. With 121.9 million visits since its June 2021 launch, it has found a large audience in the casual physics-platformer space on Roblox.

The game progresses through 9 levels of increasing wall height, each requiring taller and more carefully balanced ragdoll towers:

• 🗺️ Stack ragdolls vertically to build platforms high enough to clear the current level's wall
• 🗺️ Ragdolls grow larger as you beat more levels, making them easier to climb but harder to balance
• 💎 Nine structured levels with escalating wall heights rewarding persistent stacking skill
• 🎭 Sandbox mode removing all level objectives for pure freeform ragdoll physics
• 🎭 Up to 20 players per server for cooperative or competitive tower-building
• 🗺️ Single-session design with no persistent currency or progression save between sessions

Economy and progression are minimal by design - this is a physics toy more than a grind game. Ragdoll size grows as a visual and mechanical reward for level completion, giving returning players a satisfying size advantage in the sandbox. No gamepasses or badges exist, keeping the experience entirely free.

Ragdoll Stack! occupies a lighter niche than deeper physics sandboxes like Ragdoll Engine or Ragdoll Simulator, offering a tightly focused stacking puzzle loop that plays well in short sessions or with a small group of friends on the 20-player servers.
