Cognitive Rondo: From My Book The Science of Rondo

10v2 Rondo in a 10×10 Yard grid. Their are 6 pairs of colors. Players are not allowed to pass to the same color player. To add difficulty have players wear four different colors (3 players each wearing same color), the same rules applies. Add another cognitive level by having one player in the grid holding a tennis ball. As the rondo is being played the players must toss and catch the tennis ball continuously in any order. This rondo is game is layered with cognitive challenges.
