Play

Sims and pets can play with each other without the use of additional objects in The Sims series. Some activities require a certain relationship score to become available. Playing always requires at least two Sims and will boost both the fun and social motives.

The Sims 2
Sims of all ages can play with each other, although Sims will reject most play interactions until they have developed a good enough relationship with the initiating Sim. In addition, some play interactions are only available for children. Most activities will only grant a moderate boost to relationship when the interaction ends, although some activities will provide a steady, continuous boost to relationship. Sims will typically stop playing when their fun meters are full, or if their other motives drop too low.


 * Punch U - Punch Me: Sims will take turns punching each other in the upper arm until one Sim rubs their arm in pain or after a random number of punches, after which they will switch places. Sims with a higher body skill are able to take and deliver stronger punches. If a Sim with a high body skill is playing with a Sim that has a significantly lower body skill, they may deliver a very strong punch to the arm.
 * Play Catch: Sims will pass a baseball back and forth between each other from a distance. Sims with a higher body skill are less likely to drop the ball when catching. If a Sim with a high body skill is playing with a Sim that has a significantly lower body skill, they may throw the ball very hard at them, causing them to drop it.
 * Toss Football: Similar to playing catch, except Sims will use a pigskin football instead of a baseball.
 * Pillow Fight: Sims will have a playful pillow fight with each other. When a pillow hits a Sim, visible feathers will fly, although they do not have to be cleaned up. Sims will play in one location for a period of time before chasing each other around the room to continue the fight in a new location.
 * Tickle: One Sim will attempt to tickle the other Sim in numerous places.
 * Red Hands: Sims will play red hands and attempt to slap the other Sim's hands before they can pull them away.
 * Kicky Bag: Sims will produce a bean bag and pass it between each other with their feet, continuing until one Sim lets the bag touch the ground. Sims with a higher body skill are better able to keep the bag in the air. Multiple Sims can join in this activity depending on the amount of space available, and other Sims can spectate.
 * Water Balloon Fight: Sims will find a large, empty spot outdoors and throw water balloons at each other. Multiple Sims can join in this activity depending on the amount of space available, and no water puddles will form as a result. If Seasons is installed, having a water balloon fight will greatly lower the temperatures of the participants.
 * Rock, Paper, Scissors: Sims will play stone, paper, scissors with each other. If a Sim wins, they will gain one relationship point with the loser, while the losing Sim loses a relationship point with the winner. If both Sims tie, both Sims will gain a relationship point.
 * Show Off: Can only be done by child Sims with other children, or to older Sims. Sims can choose to demonstrate a headstand, a cartwheel, or a somersault. If the other Sim has a positive relationship with the initiating Sim, they will cheer and the stunt will be successful; otherwise, they will boo, and the initiating Sim will stumble and fail the stunt.
 * Mary Mack: Can only be done between children. Sims will sit down and play a singing-clapping game, similar to Concentration 64.
 * Cops N Robbers: Can only be done between children. Sims will run around the lot and pretend to have shootouts and duels with finger guns.
 * Swing Around: Can only be done by older Sims to children. The older Sim will pick up the child by their hands and then swing them around themselves.

Pets
Sims can play with dogs and cats as well. Much like other Sims, pets may reject the interaction if they have a poor relationship with the initiating Sim, or if they are in a bad mood. Pets may also autonomously ask to be played with.

Interactions available for dogs:
 * Razzle: Sims will tease the dog by waving their hands around its head.
 * Fetch: Sims will toss a stick for the dog to bring back. Sims may occasionally tease the dog by pretending to throw the stick and hiding it behind their back.

Interactions available for cats:
 * Cat Teaser: Sims will produce a feather duster and tease the cat with it.
 * Toss in Air: Sims will pick up the cat and toss it playfully into the air. Cats may occasionally vomit after being played with this way.
 * Finger Wiggle: Sims will wiggle their finger in front of the cat and try to get it to scratch it. Occasionally, Sims will get cut while playing,.
