Secret skill

Secret or hidden skills are skills that a Sim can gain with practice but will not appear in the interface. Cleaning is a secret skill in The Sims. There are several secret skills in The Sims 2 and The Sims 3.

The Sims

 * Cleaning
 * In The Sims, Cleaning is a hidden skill that's mostly used by the maid, community lot janitors, Servo and Bonehilda. All playable Sims and Townies have Cleaning skill, even if it's zero. However, the skill doesn't appear in the Control Panel. It cannot be changed or improved within the game, unless Sims use an object that has been hacked to affect Cleaning. Some third-party character-editing programs may allow the player to edit a Sim's Cleaning skill.

The Sims 2

 * Study
 * If a household member who is a teen or older offers or is asked to Help with a child's or teen's homework, that Sim will be able to learn how to study. This usually takes one homework session, and the child/teen being helped and the helper will each get a memory when it is completed. Then, the child or teen Sim will be able to complete homework much quicker.


 * Chess
 * Sims who play chess regularly will have more chances of winning against other Sims


 * Yoga
 * Sims who have three or more Body points get the "Do Yoga" self-interaction. Yoga is not only a skill in its own right, but doing yoga builds fitness and Body skill. However, skill at doing yoga is related to Body skill, not yoga experience. Unlike many Body-building activities, yoga does not cause a fast drop in the Hygiene meter. Also, if Seasons is installed, yoga does not raise a Sim's temperature.


 * Painting


 * The more paintings a Sim paints, the more he/she will be paid for them &mdash; even if (especially if) he/she has already maxed his Creativity.


 * Writing
 * One Writing skill point is gained whenever a Sim completes a novel. Like the Painting skill, the higher the Writing skill, the more a Sim's novels will sell for.


 * Meditation
 * Meditation is a skill that Sims from teens on up acquire if they have three or more Logic points and eight or less Playful. (Note that if a Sim's Playful score is exactly 8.00, he or she will be able to meditate.) While a Sim meditates, their motives; such as Energy or Hunger do not decay; neither does their Aspiration bar. This makes meditation useful to "save" a Platinum mood for later, such as for a promotion. It can also be useful for sick Sims, pregnant Sims, and Sims who wake up in the middle of the night. If a Sim meditates for a certain amount of time, they could learn to teleport. Meditation takes half a Sim hour to begin and up to another half an hour to stop. (It takes less time to stop if the Sim is not levitating.)


 * Dancing


 * This is a hidden skill that involves Sims getting better at the activity of dancing. Sims who are at the bottom end of the skill have very entertaining actions and moves. Teen Sims that achieve a high level in the dancing skill can qualify for the §1000 Tsang Footwork Award. A Sim with a relatively good Dancing skill has access to the social "Entertain. . . Bust a Move", which is available to use on Sims at a relatively low Lifetime Relationship of 20-30 and increases lifetime relationship by one or two points.


 * Pool
 * A skill learned by playing pool/billiards. Teens can receive the Phelps-Wilsonoff Billiards Prize of §1000 for having a high pool skill. The better a Sim is at the Pool skill, the more likely he is to succeed at Hustling pool.


 * Tai Chi


 * Sim can learn Tai Chi in Takemizu Village. Most locals there have already learned Tai Chi. Doing Tai Chi will drain hunger but fill up energy. When mastered, doing Tai Chi will build up Body skill. Tai Chi increases Fitness enthusiasm.
