Here there's no skill involved either. It's not that you have some time to catch as many ducks as possible and if you're good at it you catch more. It's that the 10 € give you the right to catch e.g. 3 ducks, so you spend the time that you need to catch 3 ducks (typically for a 7-year-old like 20 seconds, smaller kids take some more but still not long) and then you look at the score below the ducks, which is totally random. So yeah, quite similar to the claw machine although at least they don't have the farce that you could win an iPhone (Actually you can buy more ducks to get higher scores, so the prizes need to be linear. I have seen parents spend like €50 for their kid to get a toy that could be at most €10).
