🧬 CRISPR Complete Guide
Transform your horses into genetic masterpieces. This complete CRISPR tutorial covers unlocking the lab, extracting DNA, editing critical genes, and creating the perfect racing specimen.
What is CRISPR in Horsey Game?
CRISPR is the genetics lab that lets you directly edit your horse's DNA. Instead of relying on random breeding outcomes, you can precisely control traits like speed, stamina, intelligence, and physical characteristics to create the ultimate racing machine.
Each horse has the potential to become a work of genetic art - who are you to deny them of this right?
Step 1: Unlocking the CRISPR Lab
The CRISPR genetics lab starts without power. You need to restore electricity before you can use any of the equipment.
How to restore power
- Follow the power cables from the lab to the power plant location.
- Find the hamster wheel inside the power plant.
- Place a horse into the wheel (crocodiles work great for this).
- The wheel will start turning and restore power to the lab.
- Return to the CRISPR lab - it's now ready to use.
Pro tip: Throw a couple of crocodiles into the wheel for reliable power generation.
Step 2: Extracting DNA
Once the lab has power, you can extract DNA from any horse to analyze and edit its genetic code.
DNA extraction process
- Place your horse onto the examination table inside the lab.
- Use the dial in the middle of the machine to set it to "DNA EXTRACT" mode.
- Pull the lever on the side of the machine.
- The machine will extract DNA into a beaker.
- Click the computer and select "COPY" to copy the DNA sequence to your clipboard.
The DNA will be copied as a text sequence that you can paste into editing tools. Keep this sequence safe - it's your horse's complete genetic blueprint.
Step 3: Using the Online CRISPR Tool
The community has created a powerful online tool that makes gene editing much easier than doing it manually.
How to use the editing tool
- Visit the Horsey CRISPR Tool
- Paste your horse's DNA sequence into the input box.
- Click "Analyze Genome" to populate all the gene helixes.
- Enable "Auto-copy on edit" so changes are automatically copied to your clipboard.
- Edit individual genes by clicking on them and changing the base pairs.
- Copy the modified DNA back into the game.
Optional: Merge All
You can select "Merge All" to use the first strand as the source of truth. This makes traits more predictable and editing easier, but it may change your horse's current characteristics. Use this at your own risk, but it's recommended for serious optimization work.
Step 4: Critical Genes to Edit
These are the most important genes for creating a competitive racing horse. Start with these before experimenting with other traits.
Old Age (Helix 2)
Set to: A or T
Prevents degradation with age. This is critical for long-term performance.
Brain Spastic (Helix 3)
Set to: T or C
Prevents random spasms during racing. Essential for consistent performance.
Muscle Use (Helix 3)
Set to: C or G
Gives optimal body-wide force multiplier for racing speed.
Break Force (Helix 5)
Set to: T or G
Controls stamina drain rate. These values give infinite stamina.
White Is Lethal (Helix 6)
Set to: C, G, or A
When active, white-coated offspring die at birth. Disable this to prevent breeding failures.
Leg Strength (Helix 9)
Set to: C
Affects leg force. C is ideal for racing performance.
Teeth Shape (Helix 13)
Adjust based on desired diet
Directly affects what food the horse eats. Change this to control their diet (most players prefer herbivores).
Narcolepsy (Helix 19)
Set to: A, T, or C
Prevents random sleeping during races. Critical for competitive horses.
High Intellect (Helix 19)
Disable unless you want stubborn horses
High intelligence makes horses stubborn and they may even open rival yards. Disable for obedient racers.
Locomotion Sync (Helix 19)
Set to: T
Keeps limbs coordinated during movement. Essential for smooth racing.
Speed Factor (Helix 19)
Set to: T
Directly affects speed. T gives the best racing results.
Spinal Locomotion (Helix 19)
Set to: C or G
Controls spinal movement. C or G are the safest values for racing stability.
Step 5: Advanced Experimentation
Once you've mastered the critical genes, you can experiment with other traits to create unique horses.
Experimental modifications
- Change the leg tag to modify leg type (wheels work surprisingly well for racing)
- Adjust body size and proportions for different racing styles
- Modify coat colors and patterns for aesthetic preferences
- Experiment with exotic traits from cross-species breeding
The online tool provides descriptions for most genes when you hover over them. Use these to understand what each modification will do.
🏆 Perfect Specimen Template
Here's a proven genetic template for an elite racing horse. This specimen is essentially a racecar that runs on hay.

⚠️ About the Bio Hacker NPC
You may encounter an NPC called the Bio Hacker who offers genetic modification services. Most players report poor results from this character, even after purchasing the RAM upgrade.
Community consensus
The Bio Hacker produces unpredictable and often garbage results. You have much better control using the CRISPR lab and online editing tool yourself. Save your money and skip this NPC.
FAQ
How do I unlock the CRISPR lab?
Follow the power cables to the power plant, place horses or crocodiles into the hamster wheel to restore power, then return to the lab.
What is the most important gene to edit first?
Start with Old Age (Helix 2) set to A or T to prevent degradation, and Brain Spastic (Helix 3) set to T or C to prevent random spasms during races.
Should I use the Bio Hacker NPC?
Most players report poor results from the Bio Hacker even with RAM upgrades. The online CRISPR tool gives you much more control and predictable results.
What does "Merge All" do in the editing tool?
It uses the first DNA strand as the source of truth, making traits more predictable. This may change your horse but makes editing much easier in the long run.
