Quarko turns fourteen ideas from science and mathematics into fourteen separate games: light and mirrors, charged fields, living cells, logic grids, illusions your eye builds on its own. Offline, no time limits, barely any reading.


Nothing here is a reskin. Each game is built on its own idea, with its own board, art, level campaign and Endless mode.
Every one of the fourteen opens the same way, so you never relearn the menu.


The Daily Observation pulls a single board from any of the fourteen games. Same puzzle for everyone, once a day.
Quarko is built for two minutes on a platform or two hours on a couch, and it does not care which one you pick.


Yes. All fourteen games are free to play, campaign and Endless included. There is one optional purchase, Quarko Complete, which lifts the hint limit and doubles the daily reward. It is never required to finish a level.
No. The science is the raw material, not the homework. Nothing is explained with formulas, and every board can be read by looking at it.
Yes. Every generator only hands out boards that can be solved, so there is never a dead board.
Completely. Generation, solving and progress all happen on your device.
No level ever runs out of time, and Endless has no clock at all. Two campaigns do count seconds for their stars: Spectile rewards a quick solve, and Sortropy rewards keeping the gate open as briefly as you can.
