Hide and seek
Next to tag, hide and seek is probably one of the most basic kid games out there. It can be played indoors or outdoors and is easily adaptable for lots of ages and playing areas.
Marshmallow toss
A game invented by my very own mother for our family nights when I was growing up. It’s a simple tossing game (kind of like a bean bag toss) you can set up with things you have around the house (marshmallows, muffin tins, you know).
Hot or cold
A really simple hide-and-seek type game. It’s a good kind of quiet, not-too-disruptive game for little kids involving hiding an object and giving clues to help players find it.
Newspaper
Here’s a fun game group you can use as a get-to-know-you game, or just to play with friends or family. Involves speed, memory, and usually laughter. It works well for lots of age groups, too.
Telephone
Telephone is a fun game for kids. Players whisper a phrase to each other and laugh as the phrase is misunderstood and repeated incorrectly.
