One of the most important β and most misunderstood β settings on any claw crane machine is claw strength. Too weak, and players feel cheated. Too strong, and prizes fly out too easily. Getting it right is the key to a satisfying gameplay experience, whether you're running a home arcade or a commercial setup.
In this guide, we'll walk you through exactly how to adjust claw strength, what affects it, and how to find the perfect balance.
What Controls Claw Strength?
Claw strength is determined by two main factors:
- Voltage/current settings on the motherboard or control board
- Claw spring tension β the physical springs inside the claw mechanism
Most DIY claw machine kits allow you to adjust both. Understanding which one to tweak first will save you a lot of trial and error.
Method 1: Adjusting via the Motherboard Settings
Most modern claw machine motherboards have a built-in settings menu where you can control:
- Grab strength (initial grip when the claw closes)
- Hold strength (grip maintained while the claw rises)
- Drop strength (how much the claw relaxes before dropping the prize)
Steps:
- Power on your machine and enter the operator settings menu (usually by holding the service button for 3β5 seconds)
- Navigate to Claw Settings or Strength Settings
- Adjust Grab Strength β start at 80β90% for home use
- Adjust Hold Strength β typically set 10β20% lower than grab strength
- Save settings and test with a prize
π‘ Tip for hobbyists: Start with grab strength at 85% and hold strength at 70%. This gives a satisfying grab without making it too easy.
π‘ Tip for operators: Many operators use a "weak claw" cycle β the claw grabs at full strength every 3rdβ5th play. This is adjustable in the motherboard settings and helps balance player satisfaction with profitability.
Method 2: Adjusting the Physical Spring Tension
If your motherboard settings are maxed out but the claw still feels too weak (or too strong), the issue may be with the claw springs.
Steps:
- Power off the machine
- Open the top panel to access the claw mechanism
- Locate the tension springs on each claw finger
- To increase strength: tighten the spring or move it to a higher tension hook
- To decrease strength: loosen the spring or move it to a lower tension hook
- Power on and test
β οΈ Note: Always adjust springs evenly across all claw fingers to ensure a balanced grip.
Common Claw Strength Problems & Fixes
| Problem | Likely Cause | Fix |
|---|---|---|
| Claw drops prize immediately | Hold strength too low | Increase hold strength in settings |
| Claw won't close fully | Spring tension too loose | Tighten springs or increase grab voltage |
| Claw crushes prizes | Grab strength too high | Reduce grab strength to 60β70% |
| Inconsistent grip | Uneven spring tension | Re-adjust all springs equally |
