How to play

Tap the left or right half, swipe, or use the lane buttons and arrow keys to switch currents.
Arrows on top show each lane: ▲▲▲ is fast, ▼ is a back-eddy that pushes you back. They reshuffle every few seconds and flash first.
Be in the lane of each golden shell as you reach it to build the streak. Keep out of boat shadows: each one costs a life.

When the arrows start flashing, look at the new arrangement before moving. One early lane change saves two late ones.

Switch a sea turtle across fast and slow currents to reach every shell checkpoint and dodge passing boat shadows.
