1. When upgrading vehicles on the home screen， the system will recommend the most cost-effective tier to purchase. Therefore， avoid manually buying high-tier vehicles from the shop early on. Save your diamonds for upgrading vehicles when you hit a roadblock later in the game. 2. Manage your resources wisely. Gold coins are relatively easy to obtain and should be your primary currency for vehicle upgrades in the early stages. Additionally， when you need to leave the game idle， purchase vehicles to fill your garage. Every five seconds， vehicles parked in the garage generate coins corresponding to their level， allowing you to earn a decent income while AFK. 3. Within levels， start on lanes 2 or 3. You can switch to lanes with more boost strips at any time. To ensure you clear the level， the most important thing is to drive on the boost strips as much as possible. 4. Balance diamond collection with level completion. On tracks， it‘s often impossible to maximise both boost strips and diamond collection simultaneously. Therefore， if you start with substantial initial momentum， prioritise collecting diamonds—even if they aren‘t on boost strips. Conversely， if your opening momentum is low， focus on completing the level to secure the resources from the completion reward.
