Peet Sneak is an action-adventure, dungeon crawl and strategy puzzle game with the sneaky stickman character Peet from the popular Peet A Lock and Peet Around games. Peet recently heard about a luxurious place that has secret hidden bathrooms that feature toilets with golden seats protected by patrolling security guards wearing black suits and sunglasses. Peet needs to go and won't allow anything to stop him from reaching his goal. He tasks the player with directing his movements through a maze of objects to bypass or stop the guards and reach one or more keys to unlock a bathroom on each floor of the building.
The player directs Peet around wooden crates, flower pots, desks and other objects. They prompt him to sneak stealthily around corners and hide in alcoves. They must often form strategies and solve problems to help him reach each bathroom. If Peet makes it to a bathroom, the player receives a selfie of Peet on a toilet. If Peet is captured by a guard, he has an embarrassing accident.
Peet Sneak assists the player by providing them with clues along the way. For example, it's safe for Peet to sneak through an area if a guard's head is green. A red head means danger. As with many maze games, the player also enjoys a top-down view of a floor, which makes it easier for them to see where they need Peet to go to stay away from the guards.
