57DBadger is a vertical endless block-dropping puzzle mobile game that combines block placement with line-clear scoring. Players move falling blocks left and right and rotate them; holding rotate turns them in reverse, soft drop speeds descent, hard drop locks immediately, and one block can be held in reserve. A pale ghost outline shows the landing position, and the next three blocks can be previewed. Filling a row clears it, each row scores one point, multiple rows score by row count, and dropping itself awards no points. Every eight points increases the level, and falling speed gradually accelerates. Rotating a T-shaped block into a narrow corner achieves a T-spin, still scored by lines cleared. The round ends when the stack reaches the top and a new block cannot enter. Easy to pick up yet strategically rich.
