FRAC — A different dimension

FRAC — A different dimension

Make space. Find your flow.

A spatial falling-block puzzle inspired by Frac (1990), reimagined for your browser. Move, spin and tip simple blocks inside a three-dimensional well. Complete an entire horizontal layer to clear it, and rotate your view to find the next fit.

Your well, your challenge

• Six well sizes, from a compact starter well to a wide basin and a narrow shaft, plus custom dimensions.
• Simple bars, flat squares, cubes and solid rectangular blocks. Optional small corner pieces add variety.
• Small pieces lead the mix: each shape's draw weight is inversely proportional to its occupied volume squared. The biggest blocks are rare surprises.
• Marathon for score chasing; Practice for a gentler pace with undo.
• Rotatable camera, top-down view, landing guide, hold and upcoming-piece previews.
• Keyboard and on-screen touch controls for desktop, tablet and phone.
• Interactive tutorial, local saves, records and replay support.

How to play

Fill every cell in a horizontal layer to clear it. Keep the stack below the top of the well.

Keyboard: Arrow keys move; Q/E spin; A/D and W/S tip; Space drops; C holds. Drag the well or use the view buttons to rotate the camera. Open How to play for all controls and Settings to remap keys.

Touch: Use the on-screen movement, rotation, hold and drop buttons. Drag the well to change your view. Fullscreen is available from the camera controls.

Runs directly in a modern browser with WebGL. No download or account required to play. Progress is stored locally in your browser; export a backup from Settings to keep a copy.
