The boys ripped open the package before UPS was even out of the driveway. Thank you to Hasbro for providing us a B-Daman Break Bomber Battlefield Set. Simple setup. 3 and 5 year old were figuring it out right away. Loved that the magazine holders held all 10 marbles. The game was fast paced and actually worked. Each time we launched marbles we were knocking "blocks" out which is a plus because often younger kids aren't as successful in games. My boys changed up the rules a little sometimes and the winner was whoever had the least amount of "blocks" scattered on their side of the battlefield. Overall this game would be a great idea for a birthday gift when invited to a party. Hours of fun. My young boys loved it. My husband and I also took a few turns at it.
