Block Ins is a spatial puzzle game that challenges you to fit a set of shaped blocks perfectly into a defined grid space. Each level presents you with a fixed outline and a collection of pieces — your job is to figure out the orientation and arrangement that allows every piece to fit without overlap or empty gaps. Early levels introduce you to the mechanic gently; later ones require you to try multiple configurations before finding the solution.
Drag blocks from the tray onto the grid. Most blocks can be rotated — use the rotation button or keyboard shortcut to change orientation. Try to place the largest, most irregularly shaped pieces first, as they have the fewest valid positions. Smaller pieces can usually fill in remaining gaps more flexibly.
