For players (2-4), it is important always to stay active, because the action only ceases when the cockroach was really trapped. But then it is also almost back over again. In 15 - 30 minutes can man see time fly, because the game makes you forget something like sense of time. It also has potentially addictive, because you can still get to play a round.
Personally, I would say that game is suitable from 4.5 to 8-9 years, then the court is too small and the repeat too often. The good thing is, however, the small electric cockroach one can also use it for much else. With a few Lego bricks here are no limits.
All in all highly recommended :)
The game is easy to learn and simple as well as younger players to huge fun with it.
