Key Parameter Settings Explained
Claw Strength (Grip Force)
Controls how tightly the claw grips prizes. Adjusted via the VR2 potentiometer on the mainboard or through the parameter menu. Higher values = stronger grip. Always test with a prize after adjusting to confirm the setting is appropriate for your prize type and size.
Game Time
Sets the duration of each play session β from coin insertion to claw drop. Shorter game time increases machine throughput; longer game time improves player experience. Typical settings range from 30 to 90 seconds depending on machine type and venue.
Coin Settings
Configures the number of coins or credits required per play, and the coin pulse signal. Ensure the coin acceptor pulse setting matches the mainboard's expected input to avoid credit errors.
Prize Probability (Win Rate)
Sets the probability of the claw maintaining full grip strength on a given play. Lower probability = weaker grip on most plays, with full strength only on winning plays. Adjust to balance player satisfaction with machine revenue targets. Check local regulations before adjusting win rate settings.
Return Strength
Controls the claw grip strength during the return journey (after picking up a prize). Setting this too low causes prizes to drop before reaching the chute. Setting it too high makes the machine too easy to win.
Tips for Operators
- Always test after adjusting β run several test plays after changing any parameter to verify the result before returning the machine to service.
- Document your settings β keep a record of your parameter values for each machine so you can restore them quickly after a power reset.
- Match claw strength to prize weight β heavier prizes require higher grip strength settings. Adjust separately for machines with different prize types.
- Check coin acceptor calibration β if credits are not registering correctly, recalibrate the coin acceptor before adjusting mainboard coin settings.
Compatibility Note
This parameter menu applies to the classic claw crane machine mainboard model shown in the image above. If your mainboard looks different, do not apply these settings β contact us to identify the correct parameter guide for your model.
