In Churning Seas is a hypnotic, physics-based arcade/puzzle game filled with lore. It features two different game modes which will challenge your ability to quickly make clever decisions under pressure (in "Build" mode), and to carefully plan the short and long-term consequences of your actions (in "Crystallize" mode).

• "It's hard to express how wonderful this hypnotic and unusual building/physics game is..."

In Churning Seas features two game modes "Build" & "Crystallize":

In "Build mode", you'll use your reflexes to cleverly build the highest island possible by staking up random rocks. Using some shapes as levers and others as counterweights, thinking fast, and strategically spending sparse special-effect tokens, your goal is to build a safe, sound structure and climb as high as possible before the ever-rising seas catch up on you.

In "Crystallize mode", you'll instead have all the time you need to plan how to use the laws of physics to best combine specifically numbered rocks into their highest possible value. As you progress, the simple rules to crystallize rocks will soon lead to a thrilling tension.

In both cases, please do note that hostile seas are no joke. They will test your sharp reflexes, clever planning, and determination.

Tiny stories!

Everything people have said in the reviews is true, the game is simply wonderful.

My favorite part of the game is when your island finally falls, you get a blurb of a plot, which are sometimes funny but mostly interesting to read.

Love it!

'In Churning Seas' is simply beautiful. Both game modes are fantastic and each requires a different strategy. My favorite is the crystallize mode. It's similar in gameplay to 2048, but the addition of physics makes it completely unique and much more fun. The game's atmosphere, music, graphics... this is a winner!

Excellent all around

All those glowing reviews quoted in the app's description – yeah, they're all true.

The only thing I would add is that it also has surprising replay value since each build can be infinitely different.

Just don't start singing Dolly Pardon/Kenny Rogers duets in your head. If you do, you *won't* be able to stop.
