What is Hot Wheels TechMods?

Hot Wheels TechMods is a game where you build your own cars from the ground up. Build them using different materials like rubber, steel, or glass. Use the remote control to drive your car around the world.

You can play three different modes. In the first mode, you drive around the world using the app. The goal is to collect all the coins and reach the finish line.

The second mode is similar to the first one. The goal is to collect the coins and get to the finish line.

The third mode is a little different. You have to find the treasure.
