1Codon Builder β€” Base Pairs in DNA
Choose a sequence of 3 base pairs to synthesize the matching amino acid. Click a slot to clear it and fill it again.

2Amino Acid Inventory
Collect amino acids by synthesizing codons. Different properties are color-coded β€” you'll need every type for more complex proteins.

3Synthesize Proteins
Combine amino acids into proteins β€” just like at the ribosome. Green ingredient = you have it. Red = still missing. Proteins are consumed when you create animals.
4Create Animals
Combine the right proteins to create animals. Each animal briefly appears in its natural habitat when created. The more complex the animal, the more proteins it needs.
🧬
Unlock the Chimera Generator!
You've created an animal β€” now you can freely combine appearance proteins and use AI to create your own fantasy creature. No biological rulebook, no boundaries between species.
