Leviathan Wilds is a board game released in 2024 for 1–4 players, 45–90 minutes per game, and ages 10 and up. It was designed by Justin Kemppainen and its main mechanics are Variable Player Powers, Hand Management, and Square Grid.
Long ago, the once-gentle leviathans lost their minds and tore the world apart. After generations of hiding and struggle, humanity discovered that the frenzied leviathans can be restored. Climbers willing to take the risk must explore the wilds and work together to remove a series of binding crystals to heal the leviathans roaming the world. In Leviathan Wilds, 1-4 players will confront these colossal beings, with each creature being depicted across the spread of a spiral-bound storybook that makes up the game's board. The book also forms the basis of a connected campaign mode built around the game's story, with each of twenty included scenarios estimated to last around 45 minutes. Tougher difficulty levels are also available for added replayability. Each character's deck of multi-use cards is unique, allowing them to climb, jump, and glide around the board in different ways. The number of cards left in the slim deck represents their grip on the leviathan's body; if the deck runs out, the player loses their grip and begins to fall down the board until they're able to reach a rest space, which resets their deck. Moving onto rest spaces also provides a way to regain one's grip without falling. Other spaces reduce a character's health or grip or they increase blight, a status that reduces their overall hit points. The leviathan has its own deck of cards, which triggers various effects at the beginning of a player's turn, from targeted attacks that reduce health to effects that move players between spaces or loosen their grip. As the game progresses, the leviathan gradually gains "rage", which intensifies the effect of its event cards. Players' characters can move around a square grid overlaid on the creature's body by spending action points — the number being determined by a card played at the start of their turn — and their remaining hand of ability cards to reach the crystals and reduce them to zero. Victory is achieved by reducing all crystals, which vary in strength, to zero.
Leviathan Wilds supports 1–4 players according to the catalogue. This range comes from the publisher’s listed player count, so the game can be set up for any group size within it. Some setups, rules and scoring details may still vary by player count, so check your edition’s rulebook for the exact configuration.
The listed playing time for Leviathan Wilds is 45–90 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 Leviathan Wilds 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.
Leviathan Wilds has a complexity rating of 2.6 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.
