SeaSim is a board game released in 2004 for 2 players, 30 minutes per game, and ages 10 and up. It was designed by Corné van Moorsel.
EAT THE MOST FISH! In the Sharks Sea, a lagoon at the Palantic Ocean, red and yellow sharks compete for the largest fish populations. Maneuver smartly and swim fast to eat the most fish! Both players are a type of sharks. You try to make your 'family' of 3 sharks (yellow or red sharks) the healthiest by having them hunt their desired type of fish (white, grey and brown fish). The goal is to attain a high health level, where health is the number of fish you ate less 1 (for the energy used to hunt). The populations of the 3 different types of fish grow during the game, so one needs to foresee and maneuver towards the larger fish populations to be in the right place at the right time. Optional rules include a Virus that makes the fish sick (and adds no health to a shark), an Orca which competes with the shark to eat fish, and a Current which sweeps fish around the lagoon.
SeaSim supports 2 players according to the catalogue. This is the publisher’s listed player count, so the game is designed for exactly that number of participants. Variants for other group sizes, if any, are described in the rulebook of your edition, so check it before setting up a different configuration.
The listed playing time for SeaSim is 30 minutes. This is the publisher’s estimate for a full game. The actual duration depends on the group, the player count and familiarity with the rules: first sessions usually run longer, while experienced groups often finish faster. Setup and teaching time are not included in this estimate.
The catalogue lists SeaSim for ages 10 and up. This is the publisher’s recommendation and reflects reading demands, rule complexity and small components rather than theme alone. Younger players can often join with help from an adult, so check the age guidance on your edition and consider your group’s experience with board games.
SeaSim has a complexity rating of 2.2 out of 5 from BoardGameGeek players, which makes it a medium-light game. The rating reflects how much rules knowledge, planning and decision-making a typical game demands. Expect a longer first teach for heavier games, and use a preparation guide before game night.
