Perspective

The game

Perspective is an anamorphic De Stijl puzzle: translucent red, blue and yellow slabs hang scattered through 3D space, and your job is to herd them — position by position — until, from your one fixed viewpoint, they line up into a perfect flat Mondrian. Each slab has a dashed ghost outline showing where it must land; release it close enough and it snaps home opaque with a chime while coloured particles burst. Ten compositions, a camera that slowly drifts on its own, and coloured shadows that only disappear once every slab is aligned. It is patience, depth perception and a little spatial algebra.

How to play

• Click / tap / Enter / Space to leave the title; ten tableaux (compositions) await.
• Drag a floating slab directly with the mouse or finger, or click a colour chip in the black panel and slide its X (left-right), Y (down-up) and Z (near-far) sliders — the sliders are the precision instruments.
• Arrow keys / WASD nudge the selected slab; release a slab (or let go of a slider) near its dashed ghost outline and it snaps in with a chime when the match is close enough.
• Watch the ALIGNMENT percentage and the "n OF 3 SNAPPED" counter tick up; press R to reshuffle the current composition, T or the DRIFT button to freeze the wandering camera, P / Esc to pause.
• Align every slab and the whole picture snaps opaque, the camera eases back and ALIGNED flashes; solve all ten to complete the gallery against your run time.
