If you are hosting a party where you have aged invitees, then you will have to be careful to plan the fringe activities for D&D for them meticulously. The activities for the elderly can vary a lot. You will have to consider their abilities and their interests before you plan out the fringe activities for D&D. The senior’s strength level should also be considered before you choose a game or an activity. It’s definitely beneficial to be engaging some social interaction with the aged invitees!
Trivia games

If you have guests who like to learn and then to recall the stuff, then a trivia game could be an exciting fringe activity for the seniors. You could Google to make a list of the various questions that you would want to ask. To make the activity a little relaxed, you could try out facts or fiction instead. All that you need to do is to check out some weird things and read them to the audience. The players will have to decide if what you said is a fact or a fiction.
Word games

You may want to play activities that let the aged to brainstorm. Word games could be fun for the aged. Here the host will give out a category, and the guest will have to list down things that fall under the category. So it could be “flavors of ice cream,” and the guests will have to list down all the “flavors of ice- cream” that he remembers. This will be time-bound. The player who can list down the maximum names is declared the winner.
Bingo

If it is a fringe activity for the seniors, then you cannot go wrong with it. For this, you need to have large printed cards and also make sure that the markers are easy to hold. The aged will be able to mark the numbers easily. The prices could be customized to fit the theme of the event or the interests of the group.
The aged like to reminisce

To play this activity, you will have to get some popular recordings from the era your guests would know of. Play a part of the song, and then the player who guesses the song right will win. You may also twist it a bit to let the player write down the names of the song or play the fringe activity as a team.
Guess the photo
This is another exciting game that the elderly guests are sure to enjoy. For this, you will have to ask your guests to bring their childhood photos with their names written on the back. The host will then place the picture on a board and put a number under it. The guests will go around and try to guess whose photo it is. The one who can write the maximum right answers is awarded the price.
Here are some ideas of fringe activities that you can arrange when you have senior invitees on your list. The games should be such that they are easy to learn and are also exciting to play. You may also want to customize the fringe activities for D&D as per what suits your guests. Like for example, if there is a fringe activity that involves writing on paper, then you may choose to do it verbally if possible. In addition, you can add on some Quality Corporate Gifts which they would definitely love, show them appreciaiton and sincerity!
