My daughter (age 7) was given the princess one of these when she broke her arm and could do it one handed, which was great. So I bought this jungle one for her cousin (boy aged 7) and he really enjoyed it too. Hard enough to take some time to do (1 hour per picture minimum if you leave a 7 year old to do it on their own), requires a bit of concentration which is good for them, and provides a lasting picture for the bedroom wall to feel proud of. Reckon you could do it in car too if trying to find things for long journeys. Suggest ages 5 to 8 depending on concentration ability. Need to be able to read numbers obviously. Am about to buy more for Christmas presents for godchildren!
