Take the time to consider the demographics of your audience when you are planning your indoor team building games. Age, sex, background, and many other factors play into the development of any exercise that you plan. You want to have balanced exercises where everyone is entertained and comfortable. If your audience is adults you don't want to plan an exercise that is too juvenile, and if your audience is younger children you want to make sure that they comprehend any exercise that they participate in.
Account for the size of your audience with respect to your indoor team building games. This is crucial because you don't want to have exercises that are hard to follow or instruct because the group is too large. You can also lose people's attention very fast this way, so choose games that are appropriate for the amount of people in attendance.
Gather as many ideas for games as possible from every source that you can, and then narrow them down according to steps one and two. You can look any place for inspiration that you feel will be helpful. Some possibilities are the internet, libraries, magazines, and also by talking to other people to get input, especially people who have experience creating and hosting indoor team building games.
Personalize the ideas that you have and make them your own. After you've finally settled down on a few ideas for indoor team building games, then put a personal spin on them and really adapt them to your specific setting. For example, if you are in a corporate setting then add in some relevant steps and content that is in line with your company's mission statement or motto. If you are planning games for children or young adults you could add some pop culture references to keep them entertained and the mood light and fun.
Get some input from people outside of the target audience prior to playing your indoor team building games live. This is a really important step because you can get feedback and make any necessary changes before going live with them.
Have fun, relax, and don't worry if they don't go exactly as planned. Most people are very forgiving of people leading games like this and they realize all the preparation that has gone in. If people don't understand a step or there is a small hiccup don't sweat it, just work through it and have fun.
