Detective Adventure Game - Harry Quantum 3: Cheese Carnival

Rating: 8.7/10 - 293 votes

Show off your super sleuthing skills in another fun detective adventure with this enigmatic private investigator. Harry Quantum 3: Cheese Carnival is a challenging and quirky analytical thinking puzzle and hidden object-themed game for older kids / teens where you must collect and combine items in order to solve the head-scratching mystery of the missing carnival goers (and to find some delicious green cheese for your alien buddy).

Harry Quantum’s world sure is filled with wacky characters, odd scenarios, and tricky brain teasers. Playing as the skilled detective, you must uncover the mystery by clicking on various interesting objects, combining items to make tools, and generally getting up to some top-class snooping around!

Sharp eyes, good logic, smart strategy, and sheer tenacity are essential skills required here as you move between game areas, trying to unlock different elements and mysteries. Ok Harry, it's time to live up to your detective hero status, and get into the thick of the action.

How to Play: This game currently does not work on IE11, but should work for you on Chrome, Safari, Firefox, and Microsoft Edge.

At the beginning of the game, Harry is informed that there are people going missing from the nearby Cheese Carnival. Harry’s alien sidekick requests that you go to the Carnival and obtain proof, as well as some green cheese (Apparently, green cheese is a preferred delicacy in outer space!).

Using your computer mouse or touchpad, you must click on any interesting items in each scenario / game area. These items may be able to be ‘collected’ in the found items area at the bottom of the game screen (For example, Harry needs a carnival ticket from his office before he can go to the carnival).

Trial and error are part of making progress. Keep clicking, and trying to combine items until you can move forward in the case. In some instances, you may, for example, have to play mini-games in order to win prizes. Make sure to click on anything or anyone that looks interesting, and carefully read the messages that pops up. You never know when a clue might present itself!
