If you are looking to escape from a traffic jam, what could be better than playing a traffic management simulation game? (not if you’re the driver of course: don’t play this game if you’re driving, actually!!!). Traffic can create stressful situations, but with Traffix 3D, the effect is the exact opposite: you will feel pleasure simply by tapping and holding your finger on the screen and letting the cars pass through the traffic lights. Traffix 3D is actually a game derived from a Premium title powered by Infinity Games: Traffix, but it provides new mechanics, 3D graphics, 100+ cities, dozens of new vehicles and a newly developed atmosphere inspired by the minimalism from the premium version. Unlike the Premium Version, Traffix 3D is 100% free! The goal of Traffix 3D is the same as the Premium Traffix game: Avoid accidents, but at all cost. If you let a single car crash, then you will need to restart the level. You pass the level after safely delivering to their destination a specific number of cars. In other words, you must keep both cars and pedestrians happy. Lastly, you should build your car collection! There are 3 ways to unlock cars: By getting in-app currency: You can win coins by passing the levels successfully. These coins allow you to unlock rare cars. By finding keys during the gameplay and unlocking classic cars from their garages By mysterious ways that will unlock you some Crazy Cars! You will be travelling between different cities from New York, Roma, Berlin, Palermo or Seoul. More cities will be added: Feel free to drop us an e-mail if you want your city to be featured in the game.

Verdict

The call

The clearest difference is review sentiment: Open Piano at 75% against Traffix 3D's 25%. Open Piano also leads on in-app purchases (none vs 9) and ads (none vs shown). Traffix 3D's advantage is rating (4.5 vs 4.0) and ratings volume (1.4K vs 3). On price, update cadence and device support there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Traffix 3D holds the better App Store score, 4.5 against 4.0. That said, the two scores are not equally well evidenced: Traffix 3D has 1.4K ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 25% of Traffix 3D's written reviews are positive against 75% of Open Piano's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Traffix 3D ships an update monthly, Open Piano every 6 weeks. Both last shipped on October 24, 2026.
