I went to replay this as an adult yesterday (British version). I have not played this game in several years. I have not played the British version before. The Cluefinders 3rd Grade remains a stable favourite of mine to this day. The voices are quite less creepy than the American version.

I was never a smart kid, so I never was able to complete this as a 3rd grader, 4th grader.. OK UNTIL I WAS PROBABLY A TEENAGER OR ADULT.
I always preferred the Monkey Kingdom as the Goo Lagoon creeped me out and just was not my cup of tea.

How I found the games:
{GOO LAGOON}
TWIN SPIDERS was so horrifying to me as a child. I would always avoid this game as much as possible because it terrified me. Seeing it again yesterday, I still feel uncomfortable with it. Game play is still hard for me...
Crabalock attack: I loved this one. I think because I have always preferred word games. I don't recall needing help for this.
Attack-nids: I found this one far too hard. When I went through and played it yesterday, I STILL COULDN'T SEE THE DIFFERENCE.
Moths and Fleas. GROSS. I never liked this as a kid and find it hard it hard to see what they want me to do to this day.
Worms Day Out: Mum would help me with this one. It's cute but kinda icky to pick up the worms. I found it hard playing it yesterday.
River of the Goo Creature: always needed mum's help. I struggled a bit yesterday playing this, even on easy level. (I believe I have dyscalculia)
Goo Falls: I rememebr struggling for years with this but then mastering it maybe in my teen years. Playing it yesterday, I lost several beettle bags. The patterns are hard for me to see.

{Monkey Kingdom}
Address Stones. Never some help on easy level as a kid. As an adult I had to cheat on hard level. I HATE MATHS
The Queen's Calendar: so-so for me as a kid but I always needed help with this entire PC game. On hard level I did ok yesterday.
The Pit and the Vines: always needed help. I cheated yesterday.
Monument: Yeah, always needed help with this too. I couldn't be botehred reading what it said so picked up anything.
Treausre Chest: far to hard for me as a child. I played the British version yesterday, so money was different. I picked up anything.
Chasm of snakes: another maths one, so I needed help with this too. I picked up anything yesterday.
The Rings of Fire: This one drove me nuts but for some reason I actually enjoyed it, despite needing help. I cheated yesterday as I can't do maths.

{jungle canopy}
Where are you: I am not good with geography so I always needed help. I was able to do ok with it yesterday, but in the past as an adult I found it difficult.
Birds on vacation: this game is very nostalgic to me and my mum. We LOVED IT because of the cute birds. I always needed help, didn't find it hard on hard yesterday.

{lost city}
The Chamber of Order: This game was fun for me as a kid. I never found it too hard on easy level. As an adult on hard it was OK but I struggled a bit.
The Chamber of Vision: I KIND OF liked this as a kid but you have to have a keen eye to see the frames and some of the order frames don't make sense. I tried it yesterday with a frog's life cycle and wasn't sure why one frame went before another. I never liked this one.
The Chamber of Structure:. I HATED THIS AS A KID and still do to this day. On hard level I struggled yesterday and had to put it back on easy.
The Chamber of Illusion: found this one ok as a child on easy, still needed help but it was kinda fun. I liked how it was a lava lamp. I played on hard yesterday and despite getting one or two wrong, it was ok to play
The Chamber of Knowledge: This game annoyed me as a kid, I'd avoid it. I am sure it had more tiles to arrange, not just four??? I played it yesterday on hard and I made mistakes. SHows how dumb I am right?
Bottomless Pits of Doom: The final game. I always needed extensive help with this. The first 2 levels are ok to pass, but after that were too difficult for me. I tried it yesterday and it seems I haven't changed. The red andgold levels were too hard for me. I had to keep getting snagnets. I thought I'd not be able to complete the gold stage. It wasn't that I didn't understand the gameplay, it was how to place them right. I wasn't sure how to store the pieces when the storage bay was filled up.

Overall a VERY nostalgic game for me. Me and mum INTO MY ADULTHOOD would make jokes about the snagnets and sneezeberries. You have to be a very bright child to be able to play this on your own. Sadly, I was never that kind of child.
