Locked — Puzzle Game

Locked is a well-crafted puzzle experience that blends traditional brain-teasers with occasional obstacle-course elements. The focus remains on solving cleverly designed puzzles across 60 stages.

Players must navigate from point A to point B while interacting with environmental elements such as stones, buttons, ropes, and hazards like lava. The game is short but highly creative, making it perfect for players looking for a complete experience in a single session.

Armless Detective

Armless Detective is one of the most polished and visually impressive puzzle games on Roblox. In this game, you take on the role of a detective tasked with identifying the correct suspect by analyzing clues scattered throughout the map.

The game features high replayability, as each session randomizes both the evidence and the culprit from a pool of 20–24 suspects. Multiple maps and regular updates ensure that the experience remains fresh.

Key Details:

  • Suspects: 20–24 (randomized)

Currently featuring two chapters, each one culminates in a boss fight that must be completed to progress. Additional chapters are planned, expanding the experience further.

This is a game best played without prior knowledge, as its unpredictability is a core part of the fun.
