Gather the friends at one place. You will know the talent and skill level of each of your friend as you have been together for quite long so divide all of them in a manner that they are separated by their skill and speed. You can make four groups consisting of speed, skill, know-how about the sport and goalies. Take one player from each category and make a team of four players; three of them will play on the sand pitch and one of them will be a goalie.
See the number of teams that are made at the end of the division. Use numbering method to decide which two will play first and who to follow. Use any part of your body to control the ball except your feet. You can keep the ball with you for just three seconds. Make a referee from the third team or outside party who will keep the check on fouls. You can also take just three steps when you have the ball with you; after that you will have to pass it to your teammate or it will be counted as a foul play.
Use your body to block player and your strength to keep them away from intercepting the pass or do that to intercept the pass. If you think you can get the ball behind the goal line, just go for it or make a smart move by dodging the goalie.
