... likes playing something ['something' is usually a noun, but one cannot play a phone, and one cannot play a TV, or play a computer.
People do play:
games (e.g., card games),
sports (e.g., football),
musical instruments (e.g., piano).]
So, in your example the preposition with is required, e.g.,
- play with your dog
- play with your computer
- play with your friends
- play with your teammates
Hope this helps....
