Hey, That's My Fish! may look like a simple children's game, what with it's cartoony penguin playing pieces, but like an iceberg, there's a lot going on beneath the surface.
In essence, it's an area-denial game, with players moving their penguins about a disintegrating ice floe trying to gather up the most fish, and it's is a lot of fun. The quick play time also means that even if fate or poor strategy sees you definitely behind the 8 ball, you won't have to wait long before it's over and a new game can begin.
Fish! is better with more players, but is still loads of fun with just 2. It's family friendly, providing enough depth for adults to enjoy, while kids will probably enjoy the aesthetics and not be overly phased by the score. Its replayability is reduced by the time-consuming and fiddly set-up (arranging 60 hexagons randomly in 8 rows can be tiresome), but not enough to detract from the enjoyment. And for those with more games than shelf space, the game box is nice and compact.
Overall, a fun and casual game with something to appeal to most people.
