ShiftLumen

ShiftLumen is a calm spatial block puzzle played on a 4x4 grid. Each round presents a target outline made of cube cells. Your task is to take blocks from the piece pool, rotate them in 90-degree steps, and place them so they fill the target shape exactly, with no overlaps and no cells outside the outline.

Chapter mode offers 15 hand-tuned levels that gradually introduce additional block shapes. Early levels use single cubes so you can learn the controls. Later levels add dominoes, L-shaped pieces, T and S blocks, and finally pre-placed fixed blocks that reduce the space you have to work with.

Infinite challenge mode generates a fresh, solvable puzzle every round, drawing from the full set of block shapes so no two runs feel the same.

Every placement costs one move. A correct placement refunds that move, while an invalid one does not. You start each round with 12 moves. Complete the shape to score: ten points for finishing plus two points for every move left. Win five rounds in a row to unlock Extreme mode, which raises the move limit to 15 and expands the block set, with a round score capped at 30.

A statistics screen tracks your highest remaining moves, total score, fastest completion time and current win streak. Sound feedback is synthesized on the device and can be toggled in settings.
