RULES VIDEO
A polished engine-building strategy game where you become the director of a marine research institute, exploring the deep sea and running research projects. Each round, players raise four core skill tracks (Navigation, Exploration, Scholarship, Solidarity), using an active disk to act each turn and hiring skilled researchers to strengthen their engine. It's a high-end strategy Euro that delivers the joy of claiming unknown ocean tiles first and chaining hired researchers' unique abilities into explosive synergy within a limited number of actions.
※When you don't want the dead silence that comes from players sinking into deep, calculating thought over action-disk math and track synergy, or when a gamer who wants boisterous, party-style needling and interaction — direct sabotage and backstabbing with lots of laughs — ends up at the table.

Scores by situation
New faces+−
♡☆☆☆☆ [Underwhelming/entry barrier] The polished components and ocean theme are appealing, but explaining how the four tracks interlock, researcher hiring abilities, and action-disk cycling takes at least 10-15 minutes. For total newcomers or a casual couples' hangout, just grasping this tight engine-building system is already a fairly big hurdle.
Close friends+−
♡☆☆☆☆ [Study-hall vibes] Not a good fit for a close-friends session, since the core is quiet deep-thinking as everyone calculates their own track efficiency and researcher combos. There's almost no biting, shouting dopamine tension — it's far more likely to turn into a quiet study room where everyone's absorbed in designing their own board.
Strategy+−
♡♡♡♡☆ [Proven advanced strategy] A top-tier, well-made game for intermediate strategists who want to squeeze out tight yet satisfying optimization over 60-90 minutes. There's real brain-tickling catharsis when an engine built in a previous round meshes with the next to produce rich action combos, and the varied scenarios give it excellent replayability.
Couple+−
♡♡♡☆☆ [Quiet healing] Aside from competing over tile claims or shared project goals, there's no harsh interaction that directly chips away at or wrecks an opponent's engine. It's solid for couples who want to spread out at the table and sit face-to-face, each smartly and peacefully cultivating their own impressive research base in a calm battle of wits.
Duel+−
♡♡☆☆☆ [Mostly skill, some luck] The two-player rules are cleanly tuned, so tight one-on-one maneuvering works well. Still, since it's a Euro strategy structure built around meticulous engine construction and long-term tempo management, the setup weight and playtime are a bit much if you're hoping for a light bet or a quick, dramatic showdown.
Gateway+−
♡♡♡♡☆ [Recommended gateway] An exemplary game that shows off the fun of 'action disk management' and 'track-driven engine building' in the cleanest, most textbook way possible. The sense of accomplishment once you fully grasp the rules is substantial, making it the perfect stepping stone for eager, elite beginners who've played some lighter games and want to build engine-building fundamentals before moving on to serious heavyweight Euros.
