Garage upgrades

Use boosts, missions, and gear to speed up progress.

Coins and diamonds help you expand faster. Offline earnings keep progress going while you are away, and boosts, lucky spins, daily missions, and equipment upgrades give more ways to power up your garage.

Boosts

Trigger extra power when a wave needs more damage right now.

Lucky Wheel

Spin for extra resources and keep the upgrade cycle moving.

Equipment

Improve car damage and turn your front line into a stronger wall.

Wave pressure

Each merge helps your defense survive longer.

The board rewards fast decisions: keep lower cars merging, move stronger units forward, and spend your earnings before the next enemy rush arrives.
