Whenever it gets boring for you.
I think you should stop playing at about 15.
Nine.

Ha! 8.
Don't be silly, theres no age you should stop playing the NDS! I know people of all ages that play the DS. It's less of what age to stop playing the NDS but what age to stop playing certain games. My mum's best friend who is around 36 loves her DS to peices and i don't see it as a bad thing at all. I'm addicted to my DS and I'm 14.
The age you stop playing ds is when you're 11.
u should lean away from them at age and stop them by age 4
you have to stop playing little league at age 12. but you can play juniors (13-15) or seniors(16-18)
From my personal perspective during the later teenage years your child should stop playing Tinkerbell, the age range you should play with Tinkerbell is from 5-14 years of age, but you can play Tinkerbell when you 15 because its a transition year to adulthood. Tinkerbell is also played with by children of all genders.
when you feel it!
38
I don't see why not. There is no age that one should/has to 'stop' playing with toys against their own will.
