Using the Hot Wheels Monster Truck Arena Smashers Car Jump Challenge Playset is easy and fun. First, take the included 1:64 scale HW Demo Derby and the two crushable cars. You can start by practicing mini flips on the dump - truck bed. When you're ready, aim for a major flip to topple the tower of crushed cars. Look for the designated smash spots to aim at for maximum destruction. You can also use the slam launcher to send the HW Demo Derby to the top of the crushed - car tower. If you have other Hot Wheels Monster Trucks Arena Smashers sets, connect them to build a full arena. Just note that each set is sold separately and availability may vary. The colors and decorations on the cars and the playset might be different. When playing, make sure to hold the cars firmly in your hands to feel the power of the action. As for maintenance, keep the playset and cars clean and dry. Avoid dropping the cars from high places to prevent damage. This set is suitable for kids 4 years old and up, so adult supervision might be needed for younger kids.
