Atlantris

Below the surface, bubble-shaped tetrominoes drift through an aquatic board. Atlantris trades plain bricks for a water-themed puzzle field, with each piece made from four small squares. A slow drop speed leaves room to plan placement and chase a higher score.

How to play?

Guide each four-block figure into the stack, filling rows evenly across the board. Complete a full horizontal line to remove it and add points. Use the button on the right side to switch the falling figure during play. That extra swap cuts down awkward placements and helps push your record higher for a score worth sharing with friends.
