For age 10, I recommend
Dr gravely and stargazer - they are not that difficult compared to others

Any of the exit game series, but choose the lower difficulty ones for a 10 year old

Werewolf escape game - they will need some help, but this one is a lot of fun - combination lockboxes to open, etc

Escape room series - these are not very hard and use a decoder box. I think they are ok, but not particularly original

I would avoid desckcape and unlock escape games - they are more of a card based game and not a good intro.
Of the above, I like the exit game series the best - they are very clever, but the werewolf game has all the fun gadgets.
