The best online observation games

1. Huntaz
Our game: searching real streets
Huntaz is an observation game set in the real world. Each hunt takes you to real locations in Google Street View with treasure chests hidden around them. To find them you have to look properly: down side streets, around corners and along the pavements, while the clock runs.
Every chest you open adds Huntaz Points. Play a Quick Hunt alone, test yourself on the Daily Hunt that every player gets the same day, or search as a team in Scheduled Multiplayer and Sponsored Multiplayer hunts, where a chest counts once for the team, whoever spots it.

4. WorldGuessr
Reading real scenes
Street View guessing is observation at its most demanding: the language on a shop sign, the side of the road cars drive on, the shape of a bollard or the colour of the soil can all tell you where you are. WorldGuessr drops you into a real scene and scores you on how close your guess lands. It is free and supported by ads.

How to get better at observation games
Good spotters are not born with better eyes; they look more systematically. A few habits help in every kind of observation game:
- Scan in a pattern. Sweep left to right and top to bottom instead of letting your eyes jump around.
- Check the edges. Changes and hidden items often sit near borders and corners, where attention drops.
- Change your distance. Zoom out to see shapes and zoom in to check details.
- In real streets, read everything. Signs, number plates, road markings and plants carry information.
- Turn around. In Street View the thing you want is often behind you. Look all the way round before moving on.
- Take short breaks. Fresh eyes spot what tired ones miss.
Look closer
Observation in real streets
Spot-the-difference pictures are designed to be searched. Real streets are not, which makes finding something in them more satisfying. In Huntaz the treasure chests sit in real places, so every hunt trains you to notice what most people walk straight past.
Start with a Quick Hunt to get your eye in, then try the Daily Hunt and see how you compare.

Do observation games use real places?
Some do. Street View games such as WorldGuessr, Geobingo, Hide and Seek World and Huntaz use real places. Spot-the-difference and hidden object games usually use illustrations.

Sources and how we checked
We checked each game's own website on 27 October 2026 for how it plays, what is free and what needs an account or payment. Games change their features and plans often, so check the official site before you rely on any detail here.
Geotastic builds its pages in the browser with JavaScript, so we checked its official Geobingo, help and donations pages as published and indexed rather than by loading the live app. Its details are the most likely to have changed.
