Game Overview
A sprawling cartoon laboratory becomes an enormous black-and-white puzzle board, with 100 tiny mice concealed among its pipes, machines, shelves, cables, and bizarre scientific clutter. 100 Hidden Mice is a relaxed-looking but deceptively demanding hidden-object adventure built around careful observation rather than reflexes or action. Its hand-drawn style gives every corner personality, turning a single oversized location into a dense visual joke packed with odd details. The mood is playful and cozy, yet the challenge can become surprisingly intense once the obvious rodents are gone.
The objective is simple: scan the laboratory and click every mouse before the final count reaches 100. What makes that task difficult is the way the artwork uses overlapping props, dense linework, tiny silhouettes, and mischievous placements to disguise each target in plain sight. Progress comes from patience, concentration, and learning how the artist hides shapes within the environment, not from upgrades, combat, or complicated systems. Sessions work well in short bursts, but the large scene also invites players to settle in and methodically inspect every shelf and shadow.
Unlike many hidden-object games that shuffle through several themed screens or surround searches with a story campaign, this one commits to one enormous illustrated setting and lets its visual density carry the experience. The monochrome presentation is more than a stylistic choice: without bright colors to guide the eye, players have to rely on outlines and pattern recognition, making each found mouse feel earned. It suits fans of casual search-and-find games such as Hidden Folks, as well as achievement hunters looking for a compact challenge, though newcomers should expect a tougher hunt than the cheerful art initially suggests. Anyone who enjoys slowing down, studying detailed artwork, and uncovering absurd secrets in a static scene finds a satisfying little brain-teaser here.

Check that extraction completed and your PC meets the system requirements. Note any error message before choosing a fix. If it identifies a missing runtime, install the required DirectX components or Microsoft Visual C++ Redistributable from Microsoft.
My antivirus is blocking the game — is it safe?
