Sunken Treasure: Picks That Unlock a Second Round of Picks

The bonus in this underwater slot resolves in two stages, and the second is stocked by what you found in the first. Blue and Red Jewels discovered during the treasure chest picks open a separate Jewel Pick Feature once the initial dive concludes.

That linkage means the chest round is doing two jobs at once. It awards its own prizes, and it determines whether a second pick round happens and how well supplied it is. A player selecting chests is therefore not only chasing immediate rewards but building towards something that follows.

The jewel values are worth knowing before the picks begin. Blue Jewels are worth up to a hundred times the bet and the rarer Red Jewels up to five hundred times, so a Red discovery during the chest round is worth considerably more than a Blue one even though both merely qualify you for the same second feature.

The chest round itself scales with the trigger. Depending on how many Ships opened the round, players select three, four or five treasure chests, each hiding either five free games with tripled prizes or an instant reward of up to ten times the triggering bet.

That branching is worth noting. Five free games at triple prizes and an instant ten times bet are not comparable outcomes, so a player receiving several instant rewards has a very different round from one receiving several free game allocations. With three to five picks available, the mix is where most of the variance sits.

Free games can also be retriggered during the bonus round.

A Diver symbol works as the wild, substituting for all others except the scattered Ships, which open the bonus once three or more appear.

No official volatility rating is listed. A random jackpot can strike on any spin regardless of denomination, adding unpredictability on top of the two pick stages. The listed top award runs to 40,000 times your bet per line.

Sunken Treasure suits players who enjoy a bonus that builds across stages and who will value a Red Jewel discovery for what it unlocks later rather than judging picks only on their immediate reveal. Anyone treating the chest round as self-contained will miss that its jewels determine the value of everything that follows.
