A great game that can be played is an adult birthday party scavenger hunt. This one is different because guests decipher riddles and clues based on streets and neighborhoods to get them to the right place!
The teams will have a blast trying to out-hunt each other! We did this for a 50th birthday so the clues were geared towards an age range of those who were kids in the 1950's and teens in the 1960's.
Teams are separated into different groups, usually 4 per team. The teams are each assigned a car and driver. Each teams starts at different times to ensure no cheating or following.
Each team gets the same list of tasks that must be completed. For instance, you have to solve a riddle that yields the name of a street. Ward (as in Ward Cleaver, from Leave it to Beaver) is a street in our neighborhood - and the clue was Beaver's pop.
Many clues/tasks require that you get something - picture or free item - to prove that you went there and actually completed the task. You could have participants go to a park and complete a tic tac toe game and take a picture.
You could have the team all get out of the car and make a human pyramid and take a picture. If you live near the beach, you could have the team bring seaweed back. If you live out near a wooded area, you could make the teams have to bring back a pine cone.
Because each team starts at a different time, it is hard to know who wins until the very end - which makes the game that much more fun! No one gives up because they think they are behind.
The people who set up the game then check all of the work - make sure all of the tasks are completed (if tasks are not completed, time can be added to the total). Its like a scavenger hunt but in a car.
I love this adult birthday party scavenger hunt idea. I have personally played and everyone had a great time. The game is timed so the first team to complete the tasks and return wins. Each game is different and takes some thinking to win. It brings together all personality types to work together for a common goal.
