Quarc: curves, not corners

Free to play — no ads, no subscriptions, no loot boxes. Can you master the learning curve?

Curves change everything.

QUARC is a falling block puzzle game in which every piece is built from concave and convex arcs, from circles to four-pointed stars. Match the curves so they fit together neatly and filled rows will disappear. But when curves collide instead of matching, or leave impossible holes, it's a recipe for disaster.

That simple idea pulls the classic block puzzle genre into new territory where nothing looks familiar. No more stacking squares and rectangles edge-to-edge. In QUARC, you're reading the contour of the surface you have already built, and finding the piece that belongs.

No subscriptions, no ads, no loot boxes — ever.

FIVE WAYS TO PLAY Classic: endless, and it steadily gets faster. Zen: endless, and it never speeds up. The quiet, relaxing one. Stay as long as you like. Sprint: clear sixteen rows as fast as you can. A race against the clock. Survival: at first, every piece fits somewhere. As your score climbs, fewer and fewer fit anywhere. Survive. Challenge: a brand-new pre-filled board every day to surprise and exasperate you. The same board for everyone, and it resets at midnight UTC.

ON THE BOARD Golden pieces fill the gaps that ill-fitting curves leave behind. Bombs blast a piece out of midair when the shape you were given is the one shape you cannot use. A streak of ten perfect landings in a row slows the whole game down.

GAME CENTER Four leaderboards — Classic, Sprint, Survival and the daily Challenge. See where you land.
