Sandris is a Tetris-style block-puzzle game similar to Sandrix. Instead of attempting to create lines with solid blocks, as seen with Tetris, the player attempts to create and remove irregular wall-to-wall bands of colored sand using polyomino block shapes. To win, they need to achieve the highest score and level possible.
Against odd-cut stone block walls, the player directs the positions of polyomino shapes that drop into a container from above. They can rotate a block or direct it to move left or right. They can also speed up the block's descent. When it hits the bottom of the container, it turns into a pile of sand. When another block hits the pile, it also falls apart into sand grains.�
Sandris requires the player to think outside the box. The player's goal isn't to create horizontal lines. Instead, they must connect the same color of sand, even if only by a few grains, from one wall to the other one in any final shape. As a result, they must consider how sand acts naturally in the world. Instead of staying in a shape, for example, sand spreads out. The grains tend to roll down piles either in a large flow or grain by grain.
If the player fails a level, they must try to achieve the highest score from scratch. That said, they can continue to play from their last unlocked level.
