Deep Sea Adventure: Boost Board Game

One More Dive. One More Ruin.

There's a moment in every dive where greed takes over — where you tell yourself you'll grab just one more relic before heading back up. Deep Sea Adventure: Boost sharpens that moment into something almost unbearable. The oxygen is draining, your pockets are heavy, and the other divers are slowing everyone down. Now, with three new custom dice in the mix, even your best-laid plans can unravel in ways you never saw coming.

What It Is

From Oink Games — the Japanese publisher known for packing enormous fun into tiny, beautifully designed boxes — Deep Sea Adventure: Boost is an expansion to the beloved original that layers in three new dice alongside the base game rules. Each die features unusual number combinations: 0 & 3, 1 & 3, and 1 & 2. These aren't standard dice, and they don't behave like standard dice. Movement becomes harder to predict, tension spikes earlier, and the collective oxygen supply disappears faster than anyone expects. The core premise remains gloriously cruel: every relic you pick up slows the whole group down, and if you don't make it back to the submarine before the air runs out, your treasure sinks to the bottom with you.

This version of the game includes the Boost dice and is designed for 2 to 4 players, making it a tighter, sharper experience than the original six-player version — every decision lands harder when there are fewer people to blame.

Who It's For

Deep Sea Adventure: Boost is a light-to-medium game that plays in around 30 minutes, making it an easy pick-up for game night without demanding the whole evening. It suits players aged 8 and up, works well as a couples game, and shines as a devious filler between heavier titles. If you already love the original and want a fresh mechanical wrinkle, the Boost dice deliver exactly that — genuine unpredictability without overhauling what made the game great in the first place.

Features & Highlights

Oink Games is known for exceptional production quality in compact packaging, and this entry is no exception. The three new custom Boost dice are the centrepiece — physically distinct and mechanically meaningful, not just a cosmetic addition. The game retains the satisfying tactile experience of passing around tokens representing your hard-won (and quickly lost) loot, and the Boost variant plays cleanly with the existing rules rather than replacing them. If you're new to Deep Sea Adventure, this version gives you the base experience and a fresh twist in one small, shelf-friendly package.
