Disclaimer! I'm not looking for the answer, so no need to solve it. Just some help.
In this website here I have tried many times to no avail. I don't know what I am getting mixed up on. So far I have this
Five children have decided to have an ice cream for a snack. Each child has bought a cone with two different flavors at a different time than the others. With the help of the clues, could you figure out at what time each child has eaten his ice cream and its flavors?
Just one child, George, has bought an ice cream with two fruits flavors. He has bought it before Steven but one hour after Luc.
Philip has chosen either watermelon or vanilla as first flavors and coconut or chocolate as second.
One child has chosen hazelnut as first flavor and chocolate as second. He has bought his ice cream one hour before than Steven.
The child who has bought his ice cream at 4.00 pm, has chosen pistachio as second flavor but neither vanilla or watermelon as first.
Steven has chosen strawberry as second flavor. The child, who has bought his ice cream at 6.00 pm has chosen coconut flavor.
None of the ice creams have been chosen together with chocolate and strawberry.
There are two things that you've missed out on right away. The first is something you can deduce before you even read the first clue:
"Each child has bought a cone with two different flavors" - the bottom square shows the relationship between first and second flavors. You can immediately rule out chocolate-chocolate, etc.
Then from the first clue:
You can make some deductions about when Luc could have bought ice cream. Also, since George bought ice cream before Steven, 5 PM is not an option for Steven.
One additional meta hint - having an entire section empty (in this case the 1st flavor vs 2nd flavor section) indicates that you should go back through the information you've been given and double-check what deductions can be made for that section.
