Read the full game description
Koi is a serene but purposeful tile-placement game about constructing an ornamental pond in layers. Each turn, players choose between meditating—drawing cards, gaining coins, and acquiring koi—or working through a Sensei ability to add transparent tiles and features to the developing habitat. Overlapping water, bridges, lanterns, and fish create a genuinely three-dimensional tableau, but each attractive choice must also serve the current objectives. Contracts and end-game bonuses reward deliberate patterns, while an open market makes timing and valuation matter. Because the available objectives and developing ponds differ from game to game, an elegant visual arrangement is never quite the same strategic puzzle twice. The solo mode keeps the core planning intact, and multiplayer interaction remains gentle but meaningful through shared drafting pressure. Koi is approachable, tactile, and unusually photogenic, yet the action economy and layered placement leave satisfying room for foresight.
