It's a hot summer and you see a new family just moved in across the street and you know what that means, boxes! You round up your friends and a giant bag of water balloons. You quickly split into teams, start stacking boxes, and fill your water balloons because everyone knows its time to Fortify! Use the variety of boxes (Cards) to create a closed wall around your Base. The larger you make it the more friends can fit inside. The more friends you have the faster you can build or the more water balloons (Dice) you can toss at your opponents fort. Roll well and land your water balloons on boxes, rival friends, and ultimately their base to claim the day and the pride of the neighborhood!
