Killuke

Killuke is a quiet, tactile puzzle about making shapes fit. Each level gives you a handful of geometric pieces and an empty silhouette to fill, and your task is to slide, rotate and flip the pieces until they nestle together perfectly inside the outline. It starts with gentle, obvious fits and grows into satisfying little geometry problems where every piece has exactly one place it belongs — the moment the last shard clicks in and the silhouette lights up is genuinely lovely. The handling is designed to feel good. Drag a piece to move it, spin it with a smooth rotation, mirror it with a tap, and feel it snap cleanly into place when it sits right. Pieces glow softly when correctly placed, gently resist overlapping, and the board checks your solution against real geometry, so a completed shape is always truly complete rather than approximately so. There's no timer and no failure — just you, the pieces, and the shape waiting to be filled. There's plenty to work through. Dozens of hand-built silhouettes span easy to hard tiers, grouped into themed sets of figures and abstract forms, with your progress and best solutions saved as you go. A relaxed hint will settle one piece into its spot when you're stuck, an undo lets you experiment freely, and a free-play tray lets you arrange the pieces into your own creations. Wrapped in an animated title, a calm palette and its own button styling, Killuke runs completely offline with no account and no ads, in English and Estonian. Whether you want a five-minute wind-down or a long, absorbing solve, it turns a scatter of shapes into the small, repeatable pleasure of everything fitting exactly where it should.
