Around 6-7 months ago, the AJ speedrunning community had this realllly slow was of getting gems. Basically, you camp in Jamaa Township and play Jamaa Derby. This method gets around 1.5 gems per second (if done perfectly with good RNG!) Then, I came around with a pretty shoddy run, but my method was significantly better than the previous record, the record was lowered from around 9.5 minutes, to 3.5 minutes. Then, I had another run and got a 3:04 3k gems and 10:19 5k gems. After that, coltranepop came around with their superior internet and almost got a sub 3. Now, everybody here just does the Training Grounds thing to get there very fast. But, there may be certain hidden areas that give around 500 gems for finding them, such as in Return of the Phantoms, hard difficulty. Or, in Meet Cosmo, hard difficulty. I will put some mathematical calculations in to see whether one method or another is better. There are a lot of ways to get gems, so this will be very tedious and will take a long time. If you have any ideas on how to get gems fast, please tell me. Thanks! - Leafeon
You should make Animal Jam Codes disabled for sure by the way some more tips about getting gems fast? Thank you in advance!
If you're a good color-matcher, Best Dressed (land ver) takes some time, but it can score you big gems!
It's not the best for speedrunning, admittedly, and I don't speedrun any of the Gem categories, but for normal gameplay, it's been my go-to game for quick gems! Same goes for Best Guess, if you're not as good at quick design and more an animal-smarts person. If more people played Temple of Trivia, it would also apply.
