Are claw machines rigged?

From the people who sell a real coin-op claw machine for the home, with its settings menu open.

Short answer: mostly, yes, but not the way people think. On many modern claw machines the claw isn't too weak by accident. The owner sets how hard it grips, and how often it grips hard enough to hold a prize. Most plays get a grip that can lift a prize but not carry it. Every so often, on a schedule the owner picks, the claw grips at full strength. That's the play that wins.

We know because we sell one. Below is the actual menu from the control board in our machine.

The settings that decide whether you win

Press a button on the control board inside the cabinet and a menu comes up on the little screen. These are the settings that matter. "Board default" is how the board comes from the factory; an arcade owner can change any of them.

Setting	Range	Board default	What it means for you
Winning Cycle	1–999	10	One strong grip every this many plays. At 10, nine plays out of ten get a grip that can't carry a prize all the way.
Winning Mode	Fixed / Random	Fixed	Fixed: the strong grip comes on a steady count. Random: it lands somewhere in the cycle.
Bottom Grip Force	1–50	40	How hard the claw closes on the prize. This is why it looks like it grabbed it fine.
Top Grip Force	0–50	12	How hard it holds while lifting and at the top. Much weaker. This is where the prize slips out.
Return Weak Grip	0–40	13	How hard it holds on the way back to the chute. The wobble-and-drop just before the hole.
Winning Grip Force	1–50	40	The grip on the scheduled winning play. It stays strong all the way back.
Drag Back Probability	0–99	1	Chance the claw lets go on purpose, even when it's holding the prize.
Guaranteed Win Mode	Off / On	On	A guaranteed-prize feature the owner can switch on or off.

So "rigged" is the wrong word for most machines. Nobody is secretly cheating. The machine is doing exactly what it was set to do. It's closer to a slot machine with a joystick than a pure test of skill.

So is it skill or luck?

Both, but in a specific order. The schedule decides when the claw is strong enough. Your aim decides whether you use that strong grip. A perfect drop on a weak play still loses. A sloppy drop on the strong play can still lose too. That's why the same machine feels impossible one minute and easy the next.

How to win a claw machine (given how they work)

Watch before you pay. If the machine runs a fixed cycle (the board default on ours) and someone just won, the next strong grip is probably a full cycle away. If people have been losing on it for a while, the strong grip is getting closer.
Pick the prize, not the machine. Go for prizes that sit loose on top, aren't wedged in, and are close to the chute. The less distance the claw has to carry it, the less the weak grip matters.
Aim for the middle of the prize's weight, not its middle by look. A plush with a heavy head needs the claw over the head.
Look from the side as well as the front before you drop. From the front you can only judge left and right.
Set a budget before you start, and stop when it's gone. On a cycle of 10, a run of nine losses is the machine working normally.

When you own the machine, you set the odds

All of these settings work the other way at home. On our own machine you can switch on free play, set the strong grip to every play so the kids win every time, or turn it up to arcade-hard for game night with friends. Ours ships set up for home play, easy to win and with commercial prize control off. Every setting is changed with the joystick and the Start button.
